Description
ROLL OF PLUGS OF SPHAGNUM
The present disclosure relates to Sphagnum, in particular to a roll of plugs of Sphagnum.
Sphagnum is a genus of moss. It is a lower plant, or a non-vascular plant, and is an example of a bryophyte. It is often referred to as peat moss and typically grows in the wild in peatlands or wetlands. Examples of suitable habitats for Sphagnum include bogs, such as raised bogs and blanket bogs, moors, mires, and fens. Sphagnum has a particularly high capacity for maintaining water in its hyaline cells. As such, in its natural environment, Sphagnum typically grows in wet conditions such as in peatlands. Such environments are often harsh with poor environmental conditions such as temperature, wind, and rainfall, which each can contribute to difficulty in growth and establishment.
Peatlands around the world are formed when lower layers of Sphagnum decay to form peat, while the upper layer continues to grow on the surface. As a result of this, carbon is stored within the peat while the actively-growing upper Sphagnum continues sequestering carbon dioxide from the atmosphere. Peatlands cover approximately 3% of the land on the Earth's surface, but store over 500 Gigatonnes of carbon -more than all other vegetation types combined. However, due to adverse impacts on the peatlands (e.g. industrial pollution, drainage -particularly for agriculture, and peat harvesting) the actively-growing upper Sphagnum has been eroded (or is now absent) in many peatlands, thereby exposing the peat to the atmosphere. This absence of surface Sphagnum enables carbon to be released from the peatland. This is a pressing environmental issue, and damaged peatlands now contribute around 6% of global anthropogenic carbon dioxide emissions. As a result, there is a pressing need for effective peatland restoration and methods of effectively growing Sphagnum for restoration purposes. Conventional methods of peatland restoration typically involve translocafing Sphagnum from other sites including peatlands, which is clearly not sustainable. Moreover, translocating Sphagnum is sub-optimal and results in poor establishment and growth. Sphagnum can also reproduce via spores, but the abundance of spores of Sphagnum is often very low in the wild, and at most sites reproduction via spores is limited, and in any case is limited to a specific and narrow window of time in the year. As such, propagation via spores is often impractical.
Peat is also used as horticultural growing media. As this peat is harvested from the wild, this damages peatlands and ultimately exacerbates carbon emissions. There is a growing demand for alternatives to peat in growing media, and Sphagnum itself has been identified as a key peat alternative. Therefore, there exists a need for an effective and sustainable source of Sphagnum for the purposes of harvest, such as for growing media.
The present disclosure seeks to address one or more of the above problems Aspects of the invention are set out in the independent claims and preferred features are set out in the dependent claims.
According to a first aspect of the present disclosure, there is provided a roll of plugs of Sphagnum, comprising: a plurality of plugs of Sphagnum, wherein the plurality of plugs of Sphagnum comprises between 15 and 25 plugs of Sphagnum, and wherein each plug of the plurality of plugs of Sphagnum comprises: a plurality of strands of micropropagated Sphagnum plants, wherein the plurality of strands comprises between 50 and 250 strands; wherein the plurality of strands has a mean length of between 4 cm and 10 cm; wherein each plug has a dry weight of between 0.1 g and 1 g; and wherein each plug has a water content by weight of at least 90 %; and a substrate for wrapping the plurality of plugs of Sphagnum, wherein the substrate comprises a sheet having an unwrapped area comprising a length of between 200 cm and 300 cm and a width of between 5 cm and 10 cm; wherein the plurality of plugs of Sphagnum is arranged along the sheet; wherein each plug of the plurality of plugs of Sphagnum is spaced from an adjacent plug of Sphagnum on the sheet along the length of the sheet when unwrapped; wherein plurality of plugs of Sphagnum is wrapped by the sheet to form the roll of plugs of Sphagnum; and wherein the roll of plugs of Sphagnum comprises a width of between 5 cm and 10 The inventors have developed the roll of plugs of the present disclosure which provides an optimum system for packaging plugs of Sphagnum. The roll of plugs is optimised for ease of handling and for maximising growth ability by exerting an ideal compression. The width of the roll determines the ultimate size of the roll, and within the context of the defined number of plugs distributed over the substrate, this characterises a compression of the plugs. This improves the survivability of the plugs and increases the success of planting the plugs of Sphagnum, such as for peatland restoration. The plugs can be planted, such as on damaged peatlands, in order to restore the vegetation. This reduces carbon emissions from degraded peatlands, and further sequesters additional carbon through photosynthesis. Additionally, this restoration increases biodiversity and supports the ecosystem of the peatland.
Given the defined properties of the plugs, including the size and weight of the plugs, the width of the roll thus determines a compression force on each plug. In particular, in order to provide a roll of the defined width, the set number of plugs need to be wrapped with a particular tightness defining a compression. The compression defined by the roll of plugs not only securely packages the plugs, but provides an unexpected technical effect of increasing the survivability of the plugs. In particular, by providing the defined width of the roll, an optimised compression of the plugs is provided which retains water content without damaging the plug. In more detail, the maximum width of the roll ensures that the plugs are sufficiently compressed to minimise evaporation and avoid the plugs drying out. This increases the success of planting by reducing the risk of the plugs drying out during transit or storage. In addition, the minimum width of the roll ensures that the plugs are not over-compressed, thus avoiding damage to the plants. As such, the roll of plugs provides an optimal compression for increasing the survivability of plugs of Sphagnum.
The roll of plugs provides a particularly optimised arrangement for the plugs having the defined properties. In particular, plugs with between 50 and 250 strands, a mean length of between 4 cm and 10 cm, and a dry weight of between 0.1 g and 1 g have a particular resilience to being compressed without damage (e.g. crushing or breaking strands), and therefore these plugs can undergo the resulting compression from the roll of plugs without damage.
The roll of plugs is particularly advantageous because of the defined water content of the plug. The plugs each have a water content by weight of at least 90 %. This provides an optimum water content, which means the plugs have a high tolerance to drought. This is advantageous as it increases the shelf life and survivability of the plug, minimising the risk of drying out during transport and storage. Given the size of the plugs and the water content, the water retention is optimised, and even if the outer surface dries out, the inner portions can survive. The roll of plugs is particularly synergistic with plugs having this water content because the compression reduces the water loss. As such, the plugs arranged in the roll have improved survivability as the high water content can be retained due to the compression, and drying out is avoided Providing a roll with an outer width of between 5 cm and 10 cm provides an unexpected technical effect of increasing the survivability of the plugs through preventing evaporation due to the compression, which is further enhanced and optimised with plugs having a water content of at least 90 °AD.
The sheet has a length and a width when unwrapped. The length is preferably the dimension along which the sheet is wrapped. The width is preferably perpendicular to the length. Preferably, the sheet is rectangular. The width may be referred to as a height of the sheet, because when the sheet is wrapped to form the roll, this dimension forms the height of the roll.
The plugs are arranged on the sheet. Preferably, the plugs are arranged to align a length of the plug with the width of the sheet. In other words, the plugs lie across the width of the sheet. The plugs are thus preferably arranged in a row extending along the length of the sheet. When the sheet is rolled, the plugs are rolled around their width (perpendicular to their height). This slightly compresses the plugs in their width, but not their length. This has been found to minimise damage to the plugs compared to compressing their length.
The plugs are spaced from adjacent plugs along the length of the sheet. This means that adjacent plugs do not contact each other. Due to the substrate being rolled around the plugs, the substrate is arranged between the layers of the roll and therefore between layers of the plugs. This avoids contact between the plugs on different layers of the roll. Moreover, due to the spacing between plugs on the sheet, this avoids contact between adjacent plugs. This makes it easier to remove each individual plug, for example for planting. The spacing of the plugs thus avoids the plugs clumping together, making them difficult to separate. It is preferable for the spacing between plugs to be as small as possible whilst ensuring that there is enough substrate to wrap each plug to separate the plugs by the substrate and avoid contact between plugs. This makes it easier to separate the plugs for improved planting, especially on remote peatlands where planting is often performed in harsh weather conditions and may require wearing gloves (often multiple layers of gloves), which makes handling difficult. Improving ease of handling is therefore crucial.
The width of the roll is between 5 cm and 10 cm. The width of the roll is preferably the dimension perpendicular to the height of the roll. The height of the roll is preferably the dimension aligned with the width of the sheet. In other words, the length of the sheet is wrapped around the plugs increasing the width of the roll. The height of the roll is generally constant as it is defined by the width of the sheet. The plugs are generally aligned so that the lengths of the plugs are arranged through the height of the roll. It is preferable for the plugs to be slightly compressed. This reduces the size of the roll so that it is easier to handle. This is especially important when plugs are planted in remote locations such as peatlands. The compression also helps keep the plugs fresh as evaporation of water is reduced and the water content can be maintained. By providing a width of the roll of between 5 cm and 10 cm, this optimises the size of the roll and the compression of the plugs. It has surprisingly been found that a roll with an outer width of between 5 cm and 10 cm optimises the survivability of the plugs by preventing evaporation, and this has surprisingly been found to be further optimised with a water content of the plugs of at least 90 To.
The combination of the number and length of strands of Sphagnum, and the weight and water content of the plug provides a plug of Sphagnum optimised for rapid growth. Coupling this with the Sphagnum being micropropagated leads to further growth potential for the plug. The rapidly growing plug is resilient and allows for fast and effective coverage of Sphagnum when the plug is planted on an area, such as for peatland restoration. The plug can be used as an effective form of peatland restoration as the survival rate of Sphagnum is increased compared to previous methods (e.g. translocating wild Sphagnum).
Moreover, the initial establishment of Sphagnum when planted increases due to fast growth rates of the plug. Meanwhile, desired long-term results of effective Sphagnum cover can be provided, which is important in assessing the success of peatland restoration. Translocating Sphagnum from other sites results in poor survival rates, slow or unsuccessful establishment, and poor long-term growth. The plug of the present disclosure provides an improved form of Sphagnum which is more resilient and can lead to better growth and quality.
The plug is sustainable because it can be produced efficiently without significant damage to donor sites. In particular, because the Sphagnum is from a micropropagated source, damage to donor sites is minimised. For instance, translocating Sphagnum from other sites can require large amounts of donor material and can thus cause damage to the donor sites.
The plug of the present disclosure provides an improved form of Sphagnum which is more sustainable. Due to its rapid growth rates, less Sphagnum is required for restoration compared to translocated material, which in turn means even less Sphagnum is harvested from donor sites for comparable restoration effects.
As used herein, the term "plug" preferably refers to a unit of Sphagnum. In particular, the plug of Sphagnum may be referred to as a clump or cluster of Sphagnum. The plug is preferably a collection of strands of Sphagnum. A conventional plug plant is typically a small seedling plant with roots holding a small amount of growing media. Plug plants are generally grown in plug cell trays. However, Sphagnum does not have roots and thus does not have roots which penetrate and hold growing media. Thus, the plug of Sphagnum preferably substantially does not include growing media. Instead, the Sphagnum grows on the surface of the growing media, but can easily be removed from the growing media.
In some examples, the substrate may be a wrapping. For example, the substrate may be a wrap. The substrate may be a film. For example, the substrate may be made from plastic. In other examples, the substrate may be made from paper.
In some examples, the substrate is wrapped around the plurality of plugs of Sphagnum. For example, the substrate may be wrapped around each plug of the plurality of plugs of Sphagnum so that the plurality of plugs of Sphagnum is wrapped by the substrate to form the roll of plugs of Sphagnum.
In some examples, the sheet has a thickness of less than 1 mm, preferably less than 100 pm, more preferably less than 20 pm. For example, the sheet may have a thickness of between Sand 20 pm. In some examples, the sheet is a film.
In some embodiments, the plurality of plugs is arranged between layers of the sheet forming the roll. Each plug may be arranged between two concentric layers of the sheet.
In some examples, the substrate can be rolled along its length encompassing the plugs between layers of the roll.
In some examples, the plurality of plugs comprises between 18 and 22 plugs of Sphagnum. In a most preferred example, the plurality of plugs comprises 20 plugs of Sphagnum. This provides an ideal number of plugs for planting.
In some examples, the length is between 225 cm and 275 cm. In a preferred embodiment, the length is 230 cm and 250 cm. This length is particularly preferable where the plurality of plugs comprises 20 plugs.
In some examples, the width of the sheet is between 7.5 cm and 10 cm.
In some examples, the plugs can be arranged generally equally spaced along the length of the sheet.
In some examples, adjacent plugs are spaced from each other along the length of the sheet by at least 5 cm. The spacing may preferably be measured as the distance between the midpoint of adjacent plugs along the length of the sheet.
In some embodiments, adjacent plugs of the plurality of plugs are spaced from each other along the length of the sheet by between 5 cm and 15 cm.
Preferably, adjacent plugs are spaced by between 6 cm and 14 cm, more preferably between 7 cm and 13 cm, even more preferably between 8 cm and 12 cm. This ensures the spacing is minimal to avoid multiple wrappings over a single plug, whilst ensuring there is sufficient substrate to wrap each plug and avoid contact between plugs. For example, the plug may have a width of typically around 4 cm to 6 cm. When compressed, the plug may have a compressed width of typically around 6 cm to 8 cm. To account for this, and typical variations in compressed width, providing such a spacing ensures that there is a gap between adjacent plugs, even when considering the width of each plug.
In some examples, the plugs have a length of between 5 cm and 10 cm. Preferably, the plugs have a length of between 6 cm and 9 cm. This means that the length of the plugs can generally correspond to the width of the sheet and thus the height of the roll. This avoids excess sheet material which does not support the plug, while avoiding excess plug height which is not supported by the sheet material and protrudes from the roll.
In some examples, the width of the roll is between 6 cm and 9 cm, preferably between 7 cm and 8 cm. This width is particularly preferable where the plurality of plugs comprises 20 plugs as it defines the appropriate compression.
In some examples, the roll is generally cylindrical. The width of the sheet forms the height of the roll. The width of the roll may be referred to as the diameter where the roll is generally cylindrical, but it will be appreciated that the cross section may not be perfectly circular. The width may be defined as the largest distance in the width dimension. In other words, the width may be the largest distance in the axis perpendicular to the height of the roll.
In some embodiments, the plurality of strands comprises between 62 and 225 strands. This has been found to optimise the number of strands to increase the number of growing points without making the plug too large and cumbersome.
In some examples, the plurality of strands comprises between 55 and 240 strands.
Preferably, the plurality of strands comprises between 60 and 230 strands. More preferably, the plurality of strands comprises between 65 and 220 strands. Even more preferably, the plurality of strands comprises between 70 and 210 strands. Most preferably, the plurality of strands comprises between 75 and 200 strands In some embodiments, the plurality of strands has a mean length of between 6 cm and 9 cm. This has been found to optimise the length of strands to increase the amount of Sphagnum and its resilience without making the plug too long and cumbersome.
In some examples, the plurality of strands has a mean length of between 4.5 cm and 9.5 cm.
Preferably, the plurality of strands has a mean length of between 5 cm and 9 cm. More preferably, the plurality of strands has a mean length of between 5.5 cm and 8.5 cm. Even more preferably, the plurality of strands has a mean length of between 6 cm and 8 cm.
In some examples, at least 50 % of the strands of the plurality of strands have a length of between 4 cm and 10 cm. The percentage of strands is preferably the percentage by number of strands. In some examples, at least 50 % by dry weight of the strands of the plurality of strands have a length of between 4 cm and 10 cm. In this case, strands having a length of 4 cm to 10 cm form at least 50 % of the dry weight of the plurality of strands.
In some examples, at least 50 % of the strands of the plurality of strands have a length of between 1 cm and 20 cm, preferably at least 75 %, more preferably at least 90 %.

In some examples, each plug of Sphagnum has a width of less than a length of the plurality of strands of the plug. In some examples, each plug of Sphagnum has a width of less than a length of a longest strand of the plurality of strands.

In some embodiments, each plug has been cultivated in vivo. As used herein, cultivating "in vivo" preferably means cultivating outside of laboratory conditions, such as outside of in vitro, tissue culture, or micropropagation conditions. For example, after growing micropropagated Sphagnum, the Sphagnum may be transferred to and grown in vivo such as in a greenhouse to form the plug. In particular, the micropropagated Sphagnum may be cultivated in vivo to form the plug. Preferably, the plug is cultivated in vivo for at least one month, more preferably at least two months, even more preferably at least three months. Preferably, the plug is cultivated in vivo for less than twelve months, more preferably less than nine months, even more preferably less than six months.
In some examples, each of the plurality of strands of Sphagnum have been cultivated together in vivo. In some examples, the micropropagated Sphagnum has been cultivated in vivo.
In some embodiments, each plug comprises a plurality of species of Sphagnum. In other words, each plug may comprise multiple different species of Sphagnum, such as different strands of different species. In other examples, each plug may be single species, but different plugs within the roll are different species. This allows multiple species to be planted with a single roll. Providing multiple species within a single plug additionally allows for planting multiple species with each plug, further increasing the biodiversity.
In some examples, the plurality of species may include one or more species selected from: Sphagnum papillosum, Sphagnum palustre, Sphagnum capillifolium, Sphagnum medium, Sphagnum subnitens, Sphagnum cusp/datum, Sphagnum denticulatum, Sphagnum fallax, Sphagnum fimbriatum, Sphagnum squarrosum, Sphagnum tenellum, Sphagnum russowii, Sphagnum fuscum, Sphagnum angustifolium, Sphagnum australe, Sphagnum centrale, Sphagnum compactum, Sphagnum imbricatum (austinii), Sphagnum inundatum, Sphagnum pulchrum, and/or Sphagnum cristatum.
In some examples, the plurality of species may include one or more species selected from: Sphagnum papillosum, Sphagnum palustre, Sphagnum capillifolium, Sphagnum medium, Sphagnum subnitens, Sphagnum cusp/datum, Sphagnum denticulatum, Sphagnum fa//ax, Sphagnum fimbriatum, Sphagnum squarrosum, Sphagnum tenellum, and Sphagnum russowii.
In some examples, the plurality of species may include one or more species selected from: Sphagnum papillosum, Sphagnum palustre, and Sphagnum capillifolium.
In some embodiments, the plurality of species comprises Sphagnum papillosum, Sphagnum 30 palustre, and Sphagnum capillifolium.
In some embodiments, each plug comprises at least 15 % by dry weight of Sphagnum papillosum, at least 10 % by dry weight of Sphagnum palustre, and at least 5 % by dry weight of Sphagnum capillifolium.
In some examples, each plug comprises at least 40 % by dry weight of a combination of Sphagnum papillosum, Sphagnum palustre, and Sphagnum capillifolium.
In some embodiments, the plurality of species comprises Sphagnum papillosum, Sphagnum palustre, Sphagnum capillifolium, and Sphagnum medium.
In some embodiments, each plug comprises at least 20 % by dry weight of Sphagnum papillosum, at least 15% by dry weight of Sphagnum palustre, at least 10 °A, by dry weight of Sphagnum capillifolium, and at least 10 % by dry weight of Sphagnum medium.
This represents a particularly preferred embodiment of the present disclosure which provides a resilient, fast-growing, and sustainable form of Sphagnum particularly useful for peatland restoration.
The plugs can be planted, such as on damaged peatlands, in order to restore the vegetation. This reduces carbon emissions from degraded peatlands, and further sequesters additional carbon through photosynthesis. Additionally, this restoration increases biodiversity and supports the ecosystem of the peatland.
Moreover, the initial establishment of Sphagnum when planted increases due to fast growth rates of the plug. Meanwhile, desired long-term results of effective Sphagnum cover can be provided, which is important in assessing the success of peatland restoration. Translocafing Sphagnum from other sites results in poor survival rates, slow or unsuccessful establishment, and poor long-term growth. The plugs of roll of plugs provide an improved form of Sphagnum which is more resilient and can lead to better growth and quality.
The plugs are sustainable because they can be produced efficiently without significant damage to donor sites. In particular, because the Sphagnum is from a micropropagated source, damage to donor sites is minimised. For instance, translocafing Sphagnum from other sites can require large amounts of donor material and can thus cause damage to the donor sites. The plugs provide an improved form of Sphagnum which is more sustainable.
Due to its rapid growth rates, less Sphagnum is required for restoration compared to translocated material, which in turn means even less Sphagnum is harvested from donor sites for comparable restoration effects.
The plurality of strands may comprise a combination of a plurality of species of Sphagnum. It has been found that it is very difficult to establish individual species of Sphagnum in a peatland environment for effective restoration because the environment is very variable. It is not practical to select individual species for a specific environmental niche. Accordingly, providing the plurality of species within a single plug enables greater establishment by the species that thrive in the particular environmental niche in which it is planted. Providing a combination of species results in effective establishment in a variety of niches. By inclusion of a plurality of species within the plug, the plug is more robust and the survival rate of at least one of the species is increased. Different species are adapted to different conditions, and by providing a plurality of species of Sphagnum, it is more likely that at least one species will find its niche. This allows for the distribution of multiple species by planting a single plug. Mixing the species into a single plug is beneficial as a more even carpet can be achieved, whilst planting is simplified -which is especially important in remote locations such as peatlands.
The plurality of species in the plugs may comprises Sphagnum papiHosum, Sphagnum palustre, Sphagnum capillifolium, and Sphagnum medium. This specific combination of species has been found to be advantageous. It has surprisingly been found that the combination of these species results in an improved and optimised plug of Sphagnum. The defined species have beneficial properties of resilience, robustness, and fast growth. This allows for more successful restoration.
These species are robust and can tolerate drought to a higher degree than other species. In particular, Sphagnum papillosum, Sphagnum capillifolium, and especially Sphagnum medium have been found to form a dense clump which allows the plug to withstand dry conditions. The tight structure protects from dry conditions, and leads to greater survival and drought tolerance. This provides an advantage over flush species, or species that prefer wetter conditions, such as Sphagnum fallax, Sphagnum fimbriatum, or Sphagnum cuspidatum. This allows for planting in areas away from wet pools or gullies, and increases resistance to poor conditions. The inclusion of the species in the defined amounts ensures that there is enough of each of the desired species so that each can have the potential to thrive if it fits into a niche. It should be noted that the drought tolerance mentioned is relative to other species of Sphagnum, rather than other types of bryophytes or other plants.
The plug also provides resilience to support more tender species that can be included within the plug. In particular, the provision of the hardier, more drought-tolerant species defined within the plug (especially Sphagnum medium) allows for the formation of a barrier of protection which permits the inclusion of more tender species that otherwise may not be able to survive. This enhances the survivability of all species of the plug, increasing the biodiversity and improving the quality of restoration.
The plug is also quick to establish once planted as the defined species are fast growing. In addition to effective coverage and restoration, the fast growing species (especially Sphagnum medium) of the plug have been found to support slower growing species that may be included within the plug. These species can absorb nutrient quickly which allows more nutrient intolerant species to grow. This can support growth of species adapted to a particular environment, which may depend on micro-topography, hydrology, and nutrient availability.
Sphagnum palustre has been found to be a fast growing and robust species, which forms a slightly looser structure than Sphagnum papillosum, Sphagnum capillifolium, and Sphagnum medium, meaning it is less drought tolerant, but has good survival in low nutrient conditions. This combination of species has been found to complement each other and provide an optimised plug of Sphagnum. In other examples, Sphagnum palustre may be omitted from the plug.
By providing at least 10 % by dry weight of each of Sphagnum papillosum, Sphagnum palustre, Sphagnum capillifolium, and Sphagnum medium, it can be ensured that there is a sufficient amount of each of these species to contribute to the resilience of the plug, and support growth of other species. Accordingly, it has been found that a threshold of at least 10 °/ci provides a sufficient quantity of each of these particular species to establish successfully and form a barrier of protection. In addition, by providing a total of at least 55 % by dry weight of the combination of species (at least 20 % Sphagnum papillosum, at least 15 % Sphagnum palustre, at least 10 % Sphagnum capillifolium, and at least 10 % Sphagnum medium), these species contribute a significant proportion (majority) of the plug to enable the desired properties to be provided. In particular, more than half of the plug is provided by resilient species that can shield other species.
It is particularly advantageous that the plug comprises Sphagnum medium. This is an excellent carbon fixer and assists peatland restoration by forming peat effectively and aiding growth of larger moorland plants. As such, it is particularly desirable for peatland restoration.
Sphagnum medium is also a fast growing species and is particularly robust and resilient to adverse weather conditions. This can increase the survival rate and decrease the time until surface coverage is achieved. Sphagnum medium also promotes fast hummock formation which assists growth of larger moorland plants for enhanced peatland restoration, as well as eventually leading to peat formation. Sphagnum medium has been found to be a particularly resilient and hardy species, providing especially good tolerance to drought due to its fight hummock structure. Surprisingly, this not only increases the survivability of the Sphagnum medium within the plug, but promotes the survivability of the plug as a whole, supporting growth of other species, especially less resilient species.
The inclusion of at least 10 % by dry weight of Sphagnum medium ensures that there is a significant proportion of Sphagnum medium within the plug to provide the desirable properties. The presence of Sphagnum medium at this level provides a higher probability of successful establishment and thus improved results of peatland restoration.
In particular, providing at least 10 % Sphagnum medium means that there is sufficient Sphagnum medium to provide a robust and resilient population of Sphagnum medium within the plug, increasing the chances of successful establishment of Sphagnum medium to provide the desirable properties above. Achieving the successful establishment of Sphagnum medium in turn has the surprising technical effect of forming an effective protective barrier within the plug to support other species, such as more tender species.
Providing at least 10 % Sphagnum medium is also surprisingly advantageous over lower levels of Sphagnum medium. It has been found that if the plug provided smaller amounts of Sphagnum medium, for example as low as 1 °A, or even 5 %, this could lead to relatively poorer growth results because the Sphagnum medium can be deprived of an opportunity to grow, due to domination by other species within the plug, or even other organisms.
Furthermore, if the plug provided less than 10 % of Sphagnum medium, this would reduce the ability of the Sphagnum medium to form a protective barrier. In other words, when there is not enough Sphagnum medium within the plug in the first place, it is unable to establish and protect other more tender species. It has been found that at a threshold of about 10 °/ci, the Sphagnum medium can successfully establish and form a protective barrier. Below this, especially at 5 % or below, and even more so at around 1 % or below, there is simply not enough Sphagnum medium to form an effective barrier. Providing at least 10 '2/0 Sphagnum medium provides protection for the whole plug, improving survivability.
In addition, in combination with the defined size of the plug, providing at least 10 % Sphagnum medium provides a sufficient number of strands of a particular size of Sphagnum medium. This ensures good quality growth and minimises the risk of failure due to damage during transport or during growth. Overall, the at least 10 % Sphagnum medium optimises survivability of the plug.
The combination of species in the plug has been found to be particularly advantageous because these species are effective peat-forming species of Sphagnum. For example, the combination of these species provides optimal peat-forming ability. These species have been found to promote formation of peat layers by fast hummock formation and thick surface coverage. This allows for more successful restoration. Therefore, including each of these species is beneficial as peat may be more efficiently formed than other species.
Sphagnum papillosum, Sphagnum palustre, Sphagnum capillifolium, and Sphagnum medium in combination have been found to be particularly well-suited for their resilience, growth rates, and peat-forming ability. Moreover, micropropagation allows for the axenic cultivation of individual species under controlled conditions. Once it has been established that each culture is disease-free and sterile, the cultures can be combined to mix species together. The plug may provide a plurality of species which can each be micropropagated and then may be combined to form a plug of multiple species. In some examples, the combined species in the plug can be further cultivated to symbiotically support others of the plurality of species. For example, the plug of multiple species can be cultivated (e.g. in vivo, such as in a greenhouse, polytunnel, or other covered area with controlled environmental conditions, or in other cases in uncovered areas such as in a field or on a peatland). This allows the species to be cultivated and support each other for a set period before introduction to the wild when planted. This also ensures the viability and establishment of each individual species.
By providing a sufficient amount of each of these species, the desired advantages of each species can be provided. This allows each of the species to be present in an amount to contribute significantly to growth of the plug when planted. This achieves rapid and effective establishment when planted, and enhances peat-forming ability long term. The plug comprising at least 20 % by dry weight of Sphagnum papillosum means that at least 20 °A) of the dry weight of the plug is Sphagnum papiHosum. In other words, when the plug is dried to remove water, at least 20 % of the weight of the plug when dried is contributed by Sphagnum papiHosum. Equally, at least 15 % is from Sphagnum palustre, at least 10 % is from Sphagnum capillifolium, and at least 10 % is Sphagnum medium. Said another way, the dry weight of Sphagnum papillosum in the plug is at least 20 % of the dry weight of the plug, the dry weight of Sphagnum palustre in the plug is at least 15 % of the dry weight of the plug, the dry weight of Sphagnum capillifolium in the plug is at least 10 % of the dry weight of the plug, and the dry weight of Sphagnum medium in the plug is at least 10 % of the dry weight of the plug.
The plug of the present disclosure is micropropagated. This means that the Sphagnum is clonal. In other words, the Sphagnum can be clonally propagated from a small amount of initial material (explant) and can be propagated to large scales. This allows for the provision of a large amount of Sphagnum without damage to donor sites, which would otherwise be required with translocating Sphagnum from other peatland areas. Accordingly, the plug provides a more sustainable alternative.
The plug being micropropagated preferably means that the Sphagnum has been propagated under controlled laboratory conditions, such as in a culture vessel such as a petri dish, a test tube, or other sterile container. In other words, the Sphagnum may be in vitro Sphagnum.
The micropropagated Sphagnum may have been cultivated using tissue culture techniques. This means that the Sphagnum was grown using clonal tissue culture techniques to produce genetically identical plantlets. This is typically performed in a laboratory by initiating Sphagnum in vitro. This can require only a small amount of wild harvested material, reducing the environmental impact and improving the sustainability of propagating Sphagnum.
Moreover, because the plug is micropropagated, the plug can be clean and free of pests or disease because it is not harvested from the wild. The Sphagnum can be cultivated in controlled environmental conditions to minimise exposure to pests and disease. For instance, as the Sphagnum is micropropagated, the Sphagnum can be grown under sterile conditions (e.g. in vitro, for example in a laboratory). In some examples, the plug can be cultured in vivo under controlled environmental conditions (e.g. in a greenhouse). This can avoid pests and disease compared to growing outside or in the wild. Additionally, this allows the Sphagnum to become more adapted to in vivo conditions and improves the survival and growth compared to planting in vitro material straight outside or in the wild. In other examples, the plug can be cultured in vivo outside (e.g. in a field). Planting the plugs of the present disclosure, for example to restore peatlands, thereby avoids transmitting pests and disease to the restored sites. This can be important to reduce damage to the Sphagnum, but also to other species of plants or animals that are already present or being introduced through the restoration. This also avoids the potential for introducing other (e.g. vascular) plants into restored areas.
Because the Sphagnum is micropropagated, a particular desired species can be more easily selected. A particular species, optionally from a particular location, can be selected, which can be important for restoration and reintroduction purposes. In other cases, particular species that have desirable growth characteristics may be selected.
The plug comprises a plurality of strands of micropropagated Sphagnum plants. An individual plant of Sphagnum grows in a strand. Each strand is a whole plant of Sphagnum. In other words, the strands are preferably not "fragments" of Sphagnum. In other words, the plug of micropropagated Sphagnum may comprise a plurality of micropropagated Sphagnum plants.
The plurality of strands comprises between 50 and 250 strands. This ensures that the plug contains a sufficient number of strands to provide a large number of growing points whilst providing a plug that is not too big and is easily handleable. Providing at least 50 strands within the plug provides a high density of growing points, especially as the Sphagnum is micropropagated and each capitulum provides a rapid source of growth. Moreover, as the plug is micropropagated and has a high density of growing points, fewer strands are needed compared to translocated Sphagnum, for example.
The arrangement of the strands within the plug also increases the chances of establishment compared to providing the same number of strands over a lower density (such as thinly spread over a surface), because the plug together can provide water (including by virtue of its high water content) and nutrients, and can protect other strands from the environment. Therefore, the plug (i.e. strands clumped together) should be differentiated from providing a plurality of strands which are entirely separated from each other and not combined into a single unit. The plug of the present disclosure has been found to optimise the number of strands to ensure optimum survival rate whilst minimising cost and size By providing at least 50 strands, there is a sufficient number of strands of Sphagnum to grow in the event of typical rates of damage or death, taking into account transport and handling.
Additionally, it has been found that provision of at least 50 strands provides an optimum number to provide the desired species, ensuring that there is a sufficient number of each species desired.
Meanwhile, providing fewer than 250 strands ensures that the plug is of a manageable size for handling, which is especially important when the plugs are planted in remote peatlands, often by hand. Reducing the size of the plugs can increase the number planted by a single person in a day, increasing planting efficiency and reducing cost, thereby increasing the accessibility and improving the economics of peatland restoration. In some examples, there may be more strands within the plug. In other words, the plug may comprise a second plurality of strands. In other examples, the plug does not comprise a second plurality of strands. For example, the plurality of strands may consist of between 50 and 250 strands. For instance, the plug may comprise between 50 and 250 strands.
In some examples, each strand of the plurality of strands comprises a stem and a capitulum at the head of the stem. A strand of Sphagnum may comprise a stem which typically has small leaves arranged intermittently along the length of the stem. The strand can also comprise larger branches shooting off from the stem, which may fall off to form a new strand by vegetative reproduction. Sphagnum grows or spreads primarily from new offshoots called innovations. As used herein, the term "innovation" may otherwise be referred to as a "growing point". At the top of the stem, the strand may comprise a capitulum which is effectively a head or cluster of new innovations. The capitulum is the primary growth point of Sphagnum. Unlike higher plants or vascular plants, Sphagnum does not have roots. The head of the stem is preferably the top of the stem in the direction in which the strand grows.
Each strand can individually provide rapid growth. Each capitulum provides a main growth point for the stem, and therefore providing a plurality of (e.g. at least 50) capitula increases the growth potential, and especially increases the establishment ability. By providing micropropagated capitula, it has been found that this further increases the growth potential compared to wild Sphagnum because each capitulum is more juvenile and more readily leads to rapid growth of young shoots. The combination of this with the number of strands optimises the density of growing points, leading to better establishment.
In some examples, some strands of Sphagnum in the plug may not comprise a capitulum (e.g. where a capitulum has broken off). In those cases, such strands may be present in the plug but do not form part of the plurality of strands. In other words, the plug may comprise a second plurality of strands, where each strand of the second plurality of strands does not comprise a capitulum. Preferably, at least 50 % of the strands of the plurality of strands comprise a stem and a capitulum at a head of the stem, more preferably at least 75 %, even more preferably at least 90 %.
The plurality of strands has a mean length of between 4 cm and 10 cm. The mean length is an average length of the strands of the plurality of strands. This can be calculated by dividing the sum of the lengths for all strands by the number of strands. A mean length of at least 4 cm provides an average length of stem which provides improved water holding capacity, resilience, and maturity of the Sphagnum. Together, this can provide a plug of Sphagnum that establishes well and grows quickly. Moreover, because the mean length of Sphagnum is between 4 cm and 10 cm, the plug of Sphagnum has a size which makes it particularly convenient for use. In particular, the plug can be easily handled and planted.
As used herein, the length of the strand is preferably the elongate dimension of the strand when laid out to its full length from the top of the capitulum to the bottom of the stem. Thus, the length of the strand may be considered as the length of the stem including the height of the capitulum. The length is preferably perpendicular to the thickness of the stem. In other words, the length is measured when the strand is preferably arranged straight.
The plug has a dry weight of between 0.1 g and 1 g. This provides a plug of an optimum size that provides a sufficient mass of Sphagnum to establish well (especially in harsh environments) whilst being easily handleable and convenient to plant. Providing a plug with a dry weight of at least 0.1 g provides improved establishment compared to smaller amounts because the plug has a better water holding capacity than individual strands or fragments, and providing a plug with a single volume better protects the Sphagnum in the centre. The combined plug provides better resistance to environmental factors such as drought, heat, flooding, or extreme cold. The combination of the dry weight with the number of strands and the length of strands defines an optimised plug with a high density of growing points and a large number of capitula within a defined mass. This provides a beneficial number and size of strands for growth whilst ensuring the plug is a convenient size.
The plug has a dry weight of between 0.1 g and 1 g, which means that when the plug is dried it has a weight of between 0.1 g and 1 g. In other words, the dry weight of the plug is the dry weight of the Sphagnum (without water). To determine the dry weight, the plug can be dried to remove the weight of the water the Sphagnum was holding. It will be understood that in use the plug will not have a fresh weight of between 0.1 g and 1 g due to its water content.
The dry weight can be determined by removing all the water held by the Sphagnum.
Preferably, the dry weight is determined by heating the plug until there is no change in weight. This indicates that all water has been fully removed. Preferably, the plug is heated at a temperature of at least 25 °C, preferably for at least 24 hours, more preferably for at least 48 hours. Preferably, the heating is performed in a low humidity environment, preferably at less than 50 % humidity. In one preferred example, the dry weight is determined after drying the plug at a temperature of at least 110 °C for at least 24 hours. For example, the dry weight may be determined after drying the plug at a temperature of 110 °C for 24 hours. For example, the plug may be placed into an oven. By drying the plug at this temperature for this time period, all the water will be evaporated. This is a standard method for measuring the dry weight in the industry.
The plug has a water content by weight of at least 90 %. This provides the plug with sufficient water to support growth of the Sphagnum. This avoids the Sphagnum drying out and encourages initial growth especially in dry conditions. This also provides sufficient water to ensure that any water loss during transport, storage, or other processing is not sufficient to cause damage to the plug before planting. Therefore, the water content can ensure that the water content of the plug when it is planted is sufficient. This can support other strands of Sphagnum within the plug because water can be held by the plug as a whole better than individual strands, fragments, or a smaller plug.
The plug having a water content by weight of at least 90 % means that the plug comprises at least 90 °/ci water by weight. In other words, at least 90 % of the weight of the plug is water.
The water content preferably includes the water held by the plug. This preferably includes water held within the hyaline cells of each strand of Sphagnum and also between the strands of Sphagnum. In other words, less than or equal to 10 °/ci of the weight of the plug is Sphagnum. Thus, the dry weight of Sphagnum of between 0.1 g and 1 g contributes less than or equal to 10 % of the total weight of the plug including water. Said another way, the dry weight of Sphagnum is less than or equal to 10 % of the fresh weight of the plug. The fresh weight is preferably the weight of the plug including the Sphagnum and the water. Alternatively, the fresh weight may be referred to as the wet weight or the harvest weight. Thus, when the plug is weighed without drying, the weight will be the fresh weight, which corresponds to the weight of Sphagnum and water. Once dried to remove the water, the weight will be the dry weight, which corresponds to the weight of Sphagnum without water.
Therefore, the water content can be calculated by measuring the fresh weight of the plug, drying the plug, measuring the dry weight of the plug, calculating the weight of water using the difference between the fresh weight and the dry weight, and calculating the water content as the percentage contribution of the weight of water to the fresh weight of the plug.
Preferably, the water content refers to the water content by fresh weight of the plug. The fresh weight can be the weight of the plug without removing any water, for example immediately after harvest. In other words, the plug may have a water content by fresh weight of at least 90 %. Thus, at least 90 % of the fresh weight of the plug is water.
Accordingly, the plug provides an improved form of Sphagnum which results in faster establishment and resistance to drought.

EXAMPLES
EXAMPLE 1
Plug of Sphagnum Materials and Methods Forty plugs of Sphagnum were provided in accordance with the present disclosure. Individual species of Sphagnum were micropropagated. Strands of Sphagnum for each of these species of Sphagnum were then chopped and mixed together and applied to a growth surface to form forty plugs. The plugs were then cultivated in vivo in a heated indoor greenhouse. The plugs were then harvested to each form a plug, and the plugs were divided into two sets of twenty plugs, which were each rolled into a roll according to an embodiment of the present disclosure. The first roll had a height of 7.5 cm and a diameter of 7.5 cm. The second roll had a height of 7.5 cm and a diameter of 7.0 cm.
Each plug of Sphagnum comprised a plurality of species. The plugs of Sphagnum each comprised the following species: Sphagnum papillosum, Sphagnum palustre, Sphagnum capillifolium, Sphagnum medium, and Sphagnum subnitens.
The plugs of Sphagnum each comprised the following amount of each species: 25 % by dry 15 weight of Sphagnum papillosum, 15 % by dry weight of Sphagnum palustre, 25 % by dry weight of Sphagnum capillifolium, 25 % by dry weight of Sphagnum medium, and 10 % by dry weight of Sphagnum subnitens.
The forty plugs provided forty samples for measurement. After storage in the compressed roll, the forty plugs were removed from the roll for measurement.
For the forty samples, the fresh weight of each sample was measured. The fresh weight was the weight of the plug without removing water. The fresh weight is the in situ weight, and may be referred to as the harvest weight or wet weight. Therefore, the fresh weight is the weight of water following harvest. The fresh weight thus includes the weight of the Sphagnum and the water it is holding. The fresh weight was measured using a scale with a precision of 2 decimal places. The mean fresh weight was calculated for the forty samples using the measured fresh weights.
The number of strands of Sphagnum of eight random samples out of the total of forty plugs was then counted. The mean number of strands was then calculated for the eight samples using the counted number of strands of each sample.
The forty samples were then dried at 110 °C for 24 hours. This removed all the water so that only dry matter content (dried Sphagnum) remained. This provided the dry weight for each sample. The dry weight of the samples was then measured using a scale with a precision of 3 decimal places. The mean dry weight was then calculated for the forty samples using the measured dry weights.
The dry matter content was then calculated as the dry weight of Sphagnum (dry matter) compared to the fresh weight. This was calculated by dividing the dry weight by the fresh weight, expressed as a percentage. The mean dry matter content was then calculated for the forty samples using the calculated dry matter contents.
The water content was then calculated as the weight of water compared to the dry weight of Sphagnum. The weight of water was calculated as the fresh weight (including water) minus the dry weight (without water). The weight of water was then divided by the fresh weight to obtain the water content, expressed as a percentage. The mean water content was then calculated for the forty samples using the calculated water contents. The water content is equivalent to 100 % minus the dry matter content.
Results Figure 1 show a photograph of a plug of Sphagnum of one of the samples of Example 1. The results of the measurements and calculations are shown in the tables of Figures 2 and 3. Figure 2 shows the fresh weight, the dry weight, the dry matter content, and the water content for each of the forty samples. Figure 2 also shows the calculated mean for each.
The mean fresh weight was 7.69 g. The standard deviation was 1.43 g, and the standard error was 0.22 g. The minimum fresh weight was 5.28 g, and the maximum was 12.46 g.
The mean dry weight was 0.482 g. The standard deviation was 0.08 g, and the standard error was 0.01 g. The minimum dry weight was 0.355 g, and the maximum was 0.678 g.
The mean dry matter content was 6.32 %. The standard deviation was 0.55 1%, and the standard error was 0.09 %. The minimum dry matter content was 5.21 %, and the maximum 30 was 7.80 %.
The mean water content was 93.68 %. The standard deviation was 0.55 %, and the standard error was 0.09 %. The minimum water content was 92.20 %, and the maximum was 94.79 %.
Figure 3 shows the number of strands for each of the eight samples. Figure 3 also shows the calculated mean for each.
The mean number of strands was 112.75. The standard deviation was 20.43, and the standard error was 7. The minimum number of strands across the eight samples was 87, and the maximum was 145.
EXAMPLE 2
Growth of plugs of Sphagnum Materials and Methods Trials were conducted in which Trial 1 consisted of control plugs of Sphagnum and Trial 2 consisted of plugs of Sphagnum in accordance with the present disclosure.
In particular, Trial 1 consisted of: 19 % by dry weight of Sphagnum papiHosum, 18 % by dry weight of Sphagnum palustre, 8 % by dry weight of Sphagnum capillifolium, 1 % by dry weight of Sphagnum medium, 8 % by dry weight of Sphagnum subnitens, 8 % by dry weight of Sphagnum cusp/datum, 1 % by dry weight of Sphagnum denticulatum, 30 % by dry weight of Sphagnum fallax, 5 % by dry weight of Sphagnum fimbriatum, 1 % by dry weight of Sphagnum sguarrosum, and 1 % by dry weight of Sphagnum tenellum.
Trial 2 consisted of: 25 % by dry weight of Sphagnum papillosum, 15 % by dry weight of Sphagnum palustre, 25 % by dry weight of Sphagnum capillifolium, 25 % by dry weight of Sphagnum medium, and 10 % by dry weight of Sphagnum subnitens. The plugs of Trial 2 were a similar size as in Trial 1 for valid comparison. Trial 1 and Trial 2 each involved planting twenty plugs in a tray of peat. The plugs were grown in simulated summer moorland conditions for a period of 4 weeks without rainfall and without supplementing with irrigation or nutrients. This simulated planting in a moorland to assess the establishment in poor conditions, especially drought.
Results The results are shown in the photographs of Figures 4 to 7.
Figure 4 shows the control plugs of Trial 1 at the end of the growth period, and Figure 5 shows the plugs in accordance with the present disclosure of Trial 2 at the end of the same growth period. As can be seen, the plugs in Trial 2 has grown much more successfully than Trial 1. The plugs of Trial 2 are much larger and have formed a higher coverage of the tray surface than Trial 1. This demonstrates that the growth of Trial 2 has been much higher than Trial 1, even over a short period. Furthermore, the plugs of Trial 1 are much less green and are whiter, especially at the top of the plugs. In contrast, the plugs of Trial 2 are greener and show less white. This means that Trial 1 has dried out more, whilst Trial 2 has been able to survive the drought conditions more successfully. Figure 6 shows a close-up of a plug of Trial 1, clearly showing the white colour, while Figure 7 shows a close-up of a plug of Trial 2, much greener in colour with less white.
This demonstrates that the plugs in accordance with the present disclosure are much more tolerable to drought. In particular, this demonstrates the significant impact of providing the species in accordance with the present disclosure, especially providing at least 10 % Sphagnum medium. In poor conditions, the Sphagnum medium can survive, protecting the plug and increasing the quality of establishment.
Figure 8 shows a plurality of plugs 102 on a substrate 104 for forming a roll of plugs in accordance with a first embodiment of the present disclosure. The substrate 104 is a sheet, but only part of the sheet is shown. Three plugs 102 are shown, but in the first embodiment plugs 102 are arranged along the sheet. The plugs 102 are generally cylindrical, but as shown in Figures 1 and 4 to 7, may have a variety of shapes. The plugs 102 have a length of around 7 cm and a width of around 5 cm in the first embodiment. The substrate 104 is a plastic wrapping, such as cling film, and has a width of around 7 cm and a length of around 250 cm. The plugs 102 are distributed along the length of the substrate 104 with their lengths generally aligned with the width of the substrate 104. The plugs 102 are spaced apart from each other.
The substrate 104 can then be wrapped around the plugs 102 to roll the plugs 102 up within the substrate 104. The plugs 102 are wrapped around the axis of their lengths. This forms a roll of 20 plugs. The plugs 102 are rolled tightly to securely fix the plugs 102 in place but without damaging the plugs 102. The compression also aids wate retention of the plugs 102 and reduces evaporation. In the first embodiment, once rolled, the roll has an outer diameter of around 7.5 cm, and a length of around 7 cm (corresponding to the width of the substrate 104 and the length of the plugs 102). This provides an ideal compression and forms a roll of
plugs in accordance with the present disclosure.
