Description

本発明は、シカや熊などの動物による食害から、山林の樹木を守るための保護具に関するものであり、より詳しくは、樹木の根元部分を防護して前記食害から樹木を守るための保護具及び当該保護具を利用した樹木の根元保護方法に関するものである。   The present invention relates to a protector for protecting forest trees from food damage caused by animals such as deer and bears, and more specifically, protector for protecting the root part of a tree and protecting the tree from the damage. And a tree root protecting method using the protective equipment.

従前より、様々な鳥獣害による農業や林業への影響は甚大なものであり、近年は自然環境や気候の大きな変動等の影響から、前記影響は更に深刻なものとなっている。   The impact on agriculture and forestry due to various birds and beasts has been enormous for some time, and in recent years, the impact has become more serious due to the effects of natural environment and large changes in climate.

その一つとして、シカによる樹木の食害の問題がある。日本全国の山林で、スギやヒノキ、マツなどの樹木の樹皮がシカによって食べられ、或いはシカの角こすりによって剥がされるという被害(これらをまとめて「樹皮食害」と呼ぶ)が非常に深刻な問題となっている。   One of them is the problem of tree damage caused by deer. In Japan's mountain forests, the damage that bark of trees such as cedar, cypress and pine is eaten by deer or peeled off by deer horn rubbing (collectively called “bark feeding damage”) is a very serious problem It has become.

樹皮食害を受け、樹幹の一部でも樹皮が剥がれた樹木は、当該樹木内に腐朽菌が進入して材質を悪化させてしまうので、樹木の商品価値が極端に下がってしまう。また、幹の全周にわたって樹皮が剥がされるなど、被害範囲が大きい場合には、当該樹木が枯死してしまう。したがって、このような樹木に対する食害は、林業経営者らにとって非常に重大な問題である。   Trees that have suffered bark damage and have had their bark peeled off even in part of the trunk of the tree will degrade the material due to the entry of decaying fungi into the tree, resulting in a drastic reduction in the commercial value of the tree. In addition, when the damage range is large, such as when the bark is peeled over the entire circumference of the trunk, the tree will die. Therefore, such damage to trees is a very serious problem for forest managers.

このような樹皮食害に対する対策としては、シカを殺処分にしたり、樹皮食害の発生する区域全体をフェンスで囲って野生動物が侵入できないようにしたり、忌避剤を樹木に塗布したり、あるいは樹木(樹幹)の周囲にさまざまな障害物を巻きつけたりして、樹皮食害の回避、低減が試みられてきた。   Countermeasures against such bark damage include killing deer, fencing the entire area where bark damage occurs to prevent invasion of wild animals, applying repellents to trees, or trees ( Attempts have been made to avoid or reduce bark damage by wrapping various obstacles around the trunk.

しかしながら、殺処分については現状殺処分が間に合っておらず、樹皮食害は減っていない。また、自然との共生という観点からは、殺処分というのは好ましい手段とは言い難い。また、樹皮食害の発生する区域全体をフェンスで囲う方法では、長大な距離にわたってフェンスを延長する必要があり、コスト及び手間が膨大となる。さらに、忌避剤については効果持続期間が短く、また、すぐに鹿は当該忌避剤に慣れてしまう場合も多いので、やはり樹皮食害の低減には至らないというのが現状である。   However, as for the killing, the current killing is not in time, and bark damage has not decreased. Further, from the viewpoint of coexistence with nature, it is difficult to say that killing is a preferable means. Further, in the method of enclosing the entire area where bark damage occurs with a fence, it is necessary to extend the fence over a long distance, and the cost and labor are enormous. Furthermore, with regard to repellents, the duration of effect is short, and deer often become accustomed to the repellents at once, so that the current situation is that it does not lead to reduction of bark damage.

また、樹木の周囲に様々な障害物を巻きつけるという方法においては、例えば、下記特許文献1〜3に記載のものがある。すなわち、下記特許文献1においては、光反射性能を備えた保護テープを樹木の周囲に巻き付けるようにして、樹木を樹皮食害から守るための樹木保護テープ及び樹木保護方法が開示されている。また、下記特許文献2においては、透明または半透明の樹脂シートを、断面四角形以上の偶数角形状の筒体として折り畳み可能とし、その筒体の下端近傍に、切り起こしによって開口部を設け、これにより樹木を保護するようにしたツリープロテクタが開示されている。   Moreover, in the method of winding various obstructions around a tree, there exist a thing of the following patent documents 1-3, for example. That is, Patent Document 1 below discloses a tree protection tape and a tree protection method for protecting a tree from bark damage by winding a protective tape having light reflection performance around the tree. Further, in the following Patent Document 2, a transparent or translucent resin sheet can be folded as an even-angled cylinder having a square cross section or more, and an opening is provided near the lower end of the cylinder by cutting and raising. Discloses a tree protector that protects trees.

さらに、下記特許文献3には、繊維を構成要素とする生分解性を有する網状構造体と、この網状構造体を樹木にセットする、繊維を構成要素とする生分解性を有する紐状締結体とを具備する剥皮被害防護ネットが開示されている。   Furthermore, Patent Document 3 below discloses a biodegradable network structure having fibers as constituent elements, and a biodegradable string-like fastener having fibers as constituent elements, which is set on a tree. A peeling damage protection net comprising:

上記各特許文献に記載の発明によれば、保護テープ等によって物理的に樹皮を覆うので、確かに一定の食害防止効果が得られるものと思われる。   According to the invention described in each of the above patent documents, the bark is physically covered with a protective tape or the like, so that it is considered that a certain damage prevention effect is surely obtained.

しかしながら、山林における樹木の多くは山の斜面に植栽されており、このような樹木を確実に保護するためには、その根元部分、特に斜面の下側に位置する根元部分を好適に覆うなどして保護を図る必要がある。   However, many trees in mountain forests are planted on mountain slopes, and in order to reliably protect such trees, the root part, particularly the root part located on the lower side of the slope, is preferably covered. Need to be protected.

また、樹木の根元部分、特に地表面に現れた根張り部分は、複雑かつ不規則な凹凸形状を有しており、このような根張り部分についても、好適に覆うなどして保護を図る必要がある。   In addition, the root part of the tree, especially the rooting part that appears on the ground surface has a complex and irregular uneven shape, and it is necessary to protect such rooting part by suitably covering it. There is.

しかるに、上記特許文献1〜3に開示された発明は、いずれも樹木の表面を覆う部材を樹木の周囲をその周方向に周回させるようにするものであるが、上記斜面の下側に位置する根元部分や、複雑かつ不規則な凹凸形状を有する根張り部分については、その形状に樹木の表面を覆う部材が沿うこと適わない。そのため、上記特許文献1〜3に開示された保護テープ等によって覆われていない樹木の表面部分が多く樹皮食害の被害に遭っている。上述のとおり、樹皮食害により樹幹の一部でも樹皮が剥がれた樹木は、当該樹木内に腐朽菌が進入して材質を悪化させてしまうので、樹木の商品価値が極端に下がってしまう。それゆえ、相変わらず樹皮食害の損害は甚大となっているのが現状である。   However, all of the inventions disclosed in Patent Documents 1 to 3 are intended to circulate a member covering the surface of the tree in the circumferential direction around the tree, but are located below the slope. About the root part and the rooting part which has a complicated and irregular uneven | corrugated shape, the member which covers the surface of a tree is not suitable for the shape. Therefore, many surface portions of trees not covered with the protective tape disclosed in Patent Documents 1 to 3 are damaged by bark damage. As described above, a tree whose bark has been peeled off even by a part of the trunk due to bark damage causes the decay of fungi into the tree and deteriorates the material, so that the commercial value of the tree is extremely lowered. Therefore, as usual, the damage caused by bark damage is enormous.

尚、この点、上記特許文献1〜3に開示された樹木の表面を覆う部材においても、それを細かく切って張り合わせるなどして、樹木の根元部分の形状に沿うようにすることも不可能ではない。しかしながら、山林に植栽された膨大な数の樹木の一本一本に、そのような手段を講じることは、多大なる労力を必要とし、非現実的である。   In addition, in this respect, even in the member covering the surface of the tree disclosed in the above-mentioned Patent Documents 1 to 3, it is impossible to make it conform to the shape of the root of the tree by finely cutting it and pasting it. is not. However, taking such a measure for each of the enormous number of trees planted in the forest requires a great deal of labor and is unrealistic.

そこで、上記のような課題を克服すべく、本発明者は、食害を及ぼす野生動物の多くが足に何かが絡まるのを嫌うという習性を持つことに着目し、これを利用することによって野生動物を樹木に近づけないようにすることが可能であることを見出した。すなわち、本発明は、野生動物の習性を利用し、簡単な構成で、食害を及ぼす野生動物を樹木に近づけないようにして、樹木の表皮を物理的に完全に覆わなくとも樹幹の樹皮、特に樹木の根元部分の樹皮をシカなどの野生動物による食害から守ることのできる樹木の根元保護具および樹木の根元保護方法を提供することを目的とするものである。   Therefore, in order to overcome the problems as described above, the present inventor has paid attention to the fact that many wild animals that cause food damage have a habit of hating something tangled in their feet, and by using this, It has been found that it is possible to keep animals away from trees. That is, the present invention uses the habits of wild animals, has a simple structure, keeps the wild animals that cause feeding damage away from the trees, and even if the epidermis of the tree is not completely covered completely, An object of the present invention is to provide a tree root protector and a tree root protection method capable of protecting the bark of the root of a tree from damage caused by wild animals such as deer.

上記の課題を解決するため、本発明に係る樹木の根元保護具は、樹木の周囲に巻回可能な周回部材と、前記周回部材から垂下する複数の垂下部材とからなり、前記垂下部材は、柔軟性のある細長いテープ状部材により構成されることによって、風などの外力により揺動するようになされると共に、その先端側が地面を這うように配することが可能なようになされたことを特徴とする。   In order to solve the above-mentioned problem, a tree root protector according to the present invention comprises a surrounding member that can be wound around a tree, and a plurality of hanging members that hang from the surrounding member. By being composed of a flexible and long tape-like member, it can be swung by an external force such as wind, and its tip side can be arranged so as to crawl on the ground. And

本発明に係る樹木の根元保護具によれば、周回部材から垂下する複数の垂下部材を備え、当該垂下部材を柔軟性のある細長いテープ状部材により構成したことで、樹木が山の斜面に立っている場合でも、また樹木の根元(根張り部分)が複雑な凹凸形状を有している場合でも、樹木の根元部分を好適に覆って保護することが可能となる。また、垂下部材が風などの外力によって揺動し、かつその先端側が地面を這うように配されることにより、必ずしも樹木の表皮全体を完全に覆わなくともシカなどは恐れて近づかないので忌避効果があり、これによって樹皮食害を防ぐことが可能となる。すなわち、多くの野生動物は、何かが足に絡まるのを嫌うので、揺動する細長いテープ状部材を警戒して樹木に近づかない。特に、シカなどの偶蹄目の動物は、蹄の隙間に異物が挟まることを嫌うため、地面に這う何本もの細長いテープ状部材が蹄の隙間に挟まるのを恐れて近寄らない。それゆえ、必ずしも樹木の表皮全体を完全に覆わなくてもシカなどに対する忌避効果があるので、樹皮食害を防ぐことが可能となる。   According to the tree root protector according to the present invention, the tree includes a plurality of suspending members that hang from the orbiting member, and the suspending member is formed of a flexible and long tape-like member, so that the tree stands on the slope of the mountain. Even when the root of the tree (the rooted portion) has a complicated uneven shape, the root portion of the tree can be suitably covered and protected. Also, the drooping member is swung by an external force such as wind, and the tip side of the drooping member crawls the ground, so it does not necessarily come close to the entire skin of the tree, but it does not approach the deer, so it is a repellent effect This makes it possible to prevent bark damage. That is, many wild animals dislike that something is entangled with their feet, so they are not close to the tree, being wary of the swinging elongated tape-like member. In particular, since cloven-hoofed animals such as deer do not like foreign objects being caught in the gaps between the hoofs, they are not allowed to approach a number of slender tape-like members crawling on the ground. Therefore, even if the entire skin of the tree is not completely covered, there is a repelling effect on deer and the like, and bark damage can be prevented.

また、本発明に係る樹木の根元保護具において、前記垂下部材は、生分解性樹脂により形成されているようにしてもよい。このようにすれば、いったん設置した樹木の根元保護具を回収する必要がなく、かつ自然環境を害する恐れもない。   Moreover, the tree root protector which concerns on this invention WHEREIN: The said drooping member may be made to be formed with biodegradable resin. In this way, it is not necessary to collect the root protector of the tree once installed, and there is no risk of harming the natural environment.

さらに、本発明に係る樹木の根元保護方法は、上記樹木の根元保護具、すなわち樹木の周囲に巻回可能な周回部材と、前記周回部材から垂下する複数の垂下部材とからなり、前記垂下部材は、柔軟性のある細長いテープ状部材により構成され、風などの外力により、揺動するようになされた根元保護具を用いた樹木の根元保護方法であって、周回部材は、樹幹の根元近傍に周回され取り付けられるとともに、垂下部材は、その先端側が地面を這うように配されるようにしたことを特徴とする。   Furthermore, the tree root protection method according to the present invention comprises the above tree root protector, that is, a surrounding member that can be wound around the tree, and a plurality of hanging members that hang from the surrounding member. Is a method for protecting the root of a tree using a root protector composed of a flexible and long tape-like member and swinging by an external force such as wind, and the rotating member is in the vicinity of the root of the tree trunk. The drooping member is arranged so that its tip side crawls over the ground.

本発明の樹木の根元保護方法によれば、周回部材から垂下する複数の垂下部材を備え、当該垂下部材を柔軟性のある細長いテープ状部材により構成したことで、樹木が山の斜面に立っている場合でも、また樹木の根元(根張り部分)が複雑な凹凸形状を有している場合でも、樹木の根元部分を好適に覆って保護することが可能となる。   According to the tree root protecting method of the present invention, it is provided with a plurality of drooping members that hang down from the orbiting member, and the drooping member is configured by a flexible and long tape-like member, so that the tree stands on the slope of the mountain. Even when the tree has a complicated uneven shape, the root of the tree can be suitably covered and protected.

また、垂下部材が柔軟性のある細長いテープ状部材で構成されており、垂下部材が風などの外力によって揺動し、かつその先端側が地面を這うように配されることにより、必ずしも樹木の表皮全体を完全に覆わなくともシカなどは恐れて近づかないので忌避効果があり、これによって樹皮食害を防ぐことが可能となる。すなわち、多くの野生動物は、何かが足に絡まるのを嫌うので、揺動する細長いテープ状部材を警戒して樹木に近づかない。特に、シカなどの偶蹄目の動物は、蹄の隙間に異物が挟まることを嫌うため、地面に這う何本もの細長いテープ状部材が蹄の隙間に挟まるのを恐れて近寄らない。それゆえ、必ずしも樹木の表皮全体を完全に覆わなくてもシカなどに対する忌避効果があるので、樹皮食害を防ぐことが可能となる。   In addition, the drooping member is composed of a flexible and long tape-like member, and the drooping member is arranged so that the drooping member is swung by an external force such as wind and the tip side of the drooping is crawling on the ground. Even if the whole is not completely covered, deer and the like are not afraid to approach, so there is a repellent effect, which makes it possible to prevent bark damage. That is, many wild animals dislike that something is entangled with their feet, so they are not close to the tree, being wary of the swinging elongated tape-like member. In particular, since cloven-hoofed animals such as deer do not like foreign objects being caught in the gaps between the hoofs, they are not allowed to approach a number of slender tape-like members crawling on the ground. Therefore, even if the entire skin of the tree is not completely covered, there is a repelling effect on deer and the like, and bark damage can be prevented.

以上のとおり、本発明に係る樹木の根元保護具によれば、周回部材から垂下する複数の垂下部材を備え、当該垂下部材を柔軟性のある細長いテープ状部材により構成したことで、樹木が山の斜面に立っている場合でも、また樹木の根元(根張り部分)が複雑な凹凸形状を有している場合でも、樹木の根元部分を好適に覆って保護することが可能となる。また、垂下部材が風などの外力によって揺動し、かつその先端側が地面を這うように配されることにより、必ずしも樹木の表皮全体を完全に覆わなくともシカなどは恐れて近づかないので忌避効果があり、これによって樹皮食害を防ぐことが可能となる。すなわち、多くの野生動物は、何かが足に絡まるのを嫌うので、揺動する細長いテープ状部材を警戒して樹木に近づかない。特に、シカなどの偶蹄目の動物は、蹄の隙間に異物が挟まることを嫌うため、地面に這う何本もの細長いテープ状部材が蹄の隙間に挟まるのを恐れて近寄らない。それゆえ、必ずしも樹木の表皮全体を完全に覆わなくてもシカなどに対する忌避効果があるので、樹皮食害を防ぐことが可能となる。   As described above, according to the tree root protector according to the present invention, the tree includes a plurality of suspending members that hang from the revolving member, and the suspending member is formed of a flexible and long tape-like member. Even when standing on the slope of the tree, or even when the root of the tree (rooting portion) has a complex uneven shape, it is possible to suitably cover and protect the root of the tree. Also, the drooping member is swung by an external force such as wind, and the tip side of the drooping member crawls the ground, so it does not necessarily come close to the entire skin of the tree, but it does not approach the deer, so it is a repellent effect This makes it possible to prevent bark damage. That is, many wild animals dislike that something is entangled with their feet, so they are not close to the tree, being wary of the swinging elongated tape-like member. In particular, since cloven-hoofed animals such as deer do not like foreign objects being caught in the gaps between the hoofs, they are not allowed to approach a number of slender tape-like members crawling on the ground. Therefore, even if the entire skin of the tree is not completely covered, there is a repelling effect on deer and the like, and bark damage can be prevented.

また、本発明に係る樹木の根元保護方法によれば、周回部材から垂下する複数の垂下部材を備え、当該垂下部材を柔軟性のある細長いテープ状部材により構成したことで、樹木が山の斜面に立っている場合でも、また樹木の根元(根張り部分)が複雑な凹凸形状を有している場合でも、樹木の根元部分を好適に覆って保護することが可能となる。また、垂下部材が柔軟性のある細長いテープ状部材で構成されており、垂下部材が風などの外力によって揺動し、かつその先端側が地面を這うように配されることにより、必ずしも樹木の表皮全体を完全に覆わなくともシカなどは恐れて近づかないので忌避効果があり、これによって樹皮食害を防ぐことが可能となる。すなわち、多くの野生動物は、何かが足に絡まるのを嫌うので、揺動する細長いテープ状部材を警戒して樹木に近づかない。特に、シカなどの偶蹄目の動物は、蹄の隙間に異物が挟まることを嫌うため、地面に這う何本もの細長いテープ状部材が蹄の隙間に挟まるのを恐れて近寄らない。それゆえ、必ずしも樹木の表皮全体を完全に覆わなくてもシカなどに対する忌避効果があるので、樹皮食害を防ぐことが可能となる。   Further, according to the tree root protecting method according to the present invention, the tree includes a plurality of suspending members that hang down from the orbiting member, and the suspending member is formed of a flexible and slender tape-like member.

And this root | turning member 2 is made into a use condition like FIG. 1 by winding and attaching to the circumference | surroundings of the trunk of the tree W. As shown in FIG.

この実施形態における周回部材2は、乳酸系ポリマーを主成分とする生分解性の樹脂材料からなり、細長いテープ状に形成され、柔軟性を備えたものである。この周回部材2を形成する材料は、上記生分解性の樹脂材料のほか、合成樹脂、ゴム、金属などであって、樹木Wの周囲に巻回することが可能な程度に柔軟性を備えていれば、任意の材料を選択して用いることが可能である。ただし、生分解性の材料を用いる場合には、いったん根元保護具1を設置すれば、これを回収する必要がなく、かつ環境への悪影響を及ぼさないので、そのような材料を用いるのが望ましい。   The rotating member 2 in this embodiment is made of a biodegradable resin material mainly composed of a lactic acid-based polymer, is formed in an elongated tape shape, and has flexibility. In addition to the biodegradable resin material, the material for forming the surrounding member 2 is a synthetic resin, rubber, metal, or the like, and is flexible enough to be wound around the tree W. Any material can be selected and used. However, when a biodegradable material is used, once the root protector 1 is installed, it is not necessary to collect it and it does not adversely affect the environment. Therefore, it is desirable to use such a material. .

また、この実施形態における垂下部材3は、周回部材2と同じく乳酸系ポリマーを主成分とする生分解性の樹脂材料により細長いテープ状に形成され、所定の柔軟性を備えたものとなされている。この垂下部材3を形成する材料としては、上記生分解性の樹脂材料のほか、合成樹脂、ゴム、金属などであって、所定の柔軟性を備えていれば、任意の材料を選択して用いることが可能である。ただし、生分解性の材料を用いる場合には、いったん根元保護具1を設置すれば、これを回収する必要がなく、かつ環境への悪影響を及ぼさないので、やはりそのような材料を用いるのが望ましい。   Further, the drooping member 3 in this embodiment is formed in a long and narrow tape shape with a biodegradable resin material containing a lactic acid-based polymer as a main component in the same manner as the rotating member 2, and has a predetermined flexibility. . As a material for forming the hanging member 3, in addition to the biodegradable resin material, a synthetic resin, rubber, metal, etc., and any material can be selected and used as long as it has a predetermined flexibility. It is possible. However, when a biodegradable material is used, once the root protector 1 is installed, it is not necessary to recover it and it does not have an adverse effect on the environment. desirable.

この垂下部材3は、周回部材2から垂下するように構成される。垂下部材3は、接着剤等の取り付け手段によって、周回部材2に取り付けられるようにしてもよいし、あるいは周回部材2と一体的に形成されるようにしてもよい。なお、周回部材2と垂下部材3は、同じ原材料で形成されるようにしてもよく、あるいはそれぞれ別の原材料によって形成されるようにしてもよい。また、周回部材2及び垂下部材3は、例えばいったん使用された梱包用バンドや各種樹脂シートなどを再加工(リサイクル)して使用することも可能である。   The hanging member 3 is configured to hang from the orbiting member 2. The drooping member 3 may be attached to the orbiting member 2 by attachment means such as an adhesive, or may be formed integrally with the orbiting member 2. In addition, the circumference member 2 and the drooping member 3 may be made of the same raw material, or may be made of different raw materials. Further, the circulating member 2 and the drooping member 3 can be used by reworking (recycling), for example, a once-used packing band or various resin sheets.

樹木の根元保護具1は、この実施形態においては、周回部材2を樹幹Wの周囲に巻回するとともに、その両端部2a,2a同士を接着剤により結合して、樹木の根元近くに取り付けられている。周回部材2の内側面、すなわち樹幹の表皮と接する面には、複数箇所に凹凸が形成され、これにより樹幹Wの表皮に対して滑り止めになるようになされている。この滑り止めに関しては、前記のほか、例えば周回部材2の内側面に粘着性の部材を付与するようにしてもよく、或いは周回部材2をゴムなどその長手方向に伸縮自在な部材で構成するようにしてもよい。無論、この滑り止めのための手段は、これらに限られるものではない。   In this embodiment, the tree root protector 1 is attached near the tree root by winding the orbiting member 2 around the trunk W and bonding both ends 2a and 2a thereof with an adhesive. ing. Concavities and convexities are formed at a plurality of locations on the inner surface of the revolving member 2, that is, the surface in contact with the trunk of the trunk, thereby preventing slippage with respect to the outer skin of the trunk W. Regarding the anti-slip, in addition to the above, for example, an adhesive member may be provided on the inner surface of the orbiting member 2, or the orbiting member 2 may be formed of a member such as rubber that can expand and contract in the longitudinal direction. It may be. Of course, the means for preventing slipping are not limited to these.

また、周回部材2は、この実施形態においては1本のみの構成としているが、上下2段に(すなわち2本)設けるようにしてもよい(図3参照)し、あるいはそれ以上の本数にしてもよい。その場合、上下2段の周回部材2は、それぞれ別の原材料で形成するようにしてもよく、また別の形状のものとすることもできる。   Further, in this embodiment, the number of the orbiting members 2 is only one, but they may be provided in two upper and lower tiers (that is, two) (see FIG. 3) or more. Also good. In this case, the upper and lower two-stage rotating members 2 may be formed of different raw materials, or may have different shapes.

垂下部材3は、この実施形態においては上述のような構成であり、樹木の根元の形状に沿うようにして変形し、また風などの外力を受けると軽く揺動する程度の柔軟性を備えるとともに、必要以上に揺れない程度の剛性(腰の強さ)を備えているものとなされている。垂下部材3の幅や厚みなどは、前記の条件を満たしていれば任意に設定してよいが、シカなどの動物が嫌がる程度、すなわちシカなどの動物の蹄の隙間に挟まる可能性がある程度に、細く、或いは薄いものとして形成するのが好ましい。   The hanging member 3 is configured as described above in this embodiment, is deformed so as to conform to the shape of the root of the tree, and has a degree of flexibility that allows it to swing lightly when subjected to an external force such as wind. It is supposed to have rigidity (waist strength) that does not shake more than necessary. The width and thickness of the hanging member 3 may be arbitrarily set as long as the above-described conditions are satisfied. However, there is a possibility that the drooping member 3 will be caught in the gap between the hoofs of animals such as deer. It is preferably formed as a thin or thin material.

垂下部材3は、この実施形態においては周回部材2から垂直に垂れ下がる直線状のものとしているが、例えば図4に示すように、周回部材2から斜めに垂れ下がる直線状のものとすることもできる。また、図5に示すように波状(曲線状)のものとしてもよいし、図6に示すような螺旋形状のものとしてもよく、あるいはその他の形状としてもよい。このようにすれば、より野生動物の足に絡まりやすくなり、忌避効果が高くなる。さらに、垂下部材3に忌避剤を練り込んだり、塗布したりするようにしてもよい。すなわち、カプサイシンなど、動物が嫌がる忌避剤を垂下部材3に練り込み、あるいは垂下部材3の表面に塗布したりすれば、より一層有効な樹皮食害の防止が可能となる。また、垂下部材3を野生動物の嫌がる色(例えばシカに対しては黄色など)に着色するようにしてもよい。このようにすれば、より一層忌避効果を高めることが可能となる。   In this embodiment, the hanging member 3 has a linear shape that hangs vertically from the orbiting member 2, but may also be a linear shape that hangs obliquely from the orbiting member 2 as shown in FIG. 4, for example. Further, it may be wavy (curved) as shown in FIG. 5, may have a spiral shape as shown in FIG. 6, or may have other shapes. If it does in this way, it will become easy to get entangled with the leg of a wild animal, and a repellent effect will become high. Further, a repellent may be kneaded or applied to the hanging member 3. That is, if a repellent that animals dislike, such as capsaicin, is kneaded into the drooping member 3 or applied to the surface of the drooping member 3, it is possible to prevent bark damage more effectively. Moreover, you may make it color the hanging member 3 in the color (for example, yellow etc. with respect to a deer) which a wild animal dislikes. In this way, the repelling effect can be further enhanced.

また、垂下部材3は、その先端部分が地面に這うように設置されている。多くの野生動物は、足に何かが絡まるのを嫌うので、複数の垂下部材3が地面を這っている範囲には野生動物が近づかない。特に、上述したように、シカなどの偶蹄目の動物は、蹄の隙間に異物が挟まるのを嫌うため、地面に這う何本もの細長いテープ状部材が蹄の隙間に挟まるのを恐れて近寄らない。それゆえ、必ずしも樹木の表皮全体を完全に覆わなくてもシカなどに対する忌避効果があるので、樹皮食害を大きく減少させることが可能となる。   Moreover, the drooping member 3 is installed so that the front-end | tip part may crawl on the ground. Many wild animals dislike that something is entangled with their feet, so that the wild animals do not approach the range where the plurality of drooping members 3 are crawling on the ground. In particular, as described above, an cloven-hoofed animal such as a deer does not like foreign objects being caught in the gaps between the hoofs, so it is not possible to approach a number of elongated tape-like members crawling on the ground. . Therefore, there is a repellent effect on deer and the like without necessarily completely covering the entire epidermis of the tree, so that bark damage can be greatly reduced.

以上のように構成することで、樹木の根張り部分の形状を問わず、また、樹木が山間部の斜面途中に立っている場合でも(図7参照)、垂下部材3が当該根張り部分を好適に覆い、樹皮食害を防止することが可能となる。   By configuring as described above, the drooping member 3 is suitable for the rooting portion regardless of the shape of the rooting portion of the tree, and even when the tree stands on the slope of the mountain part (see FIG. 7). It is possible to prevent bark damage.

図8は、図1における樹木の根元保護具1の別の使用状態を示す図である。図1の使用状態においては、保護具1の周回部材2を直接樹幹に取り付けているが、図8の使用状態においては、樹木Wの周囲に複数の支柱Pを立設し、当該支柱Pに保護具1の周回部材2を取り付けて、これにより保護具1を樹幹の周りに周回させるようにしている。   FIG. 8 is a diagram illustrating another use state of the tree root protector 1 in FIG. 1. In the use state of FIG. 1, the orbiting member 2 of the protector 1 is directly attached to the tree trunk. However, in the use state of FIG. 8, a plurality of pillars P are erected around the tree W, and A rotating member 2 of the protector 1 is attached so that the protector 1 rotates around the trunk.

また、図9は別の使用状態を示すものであり、樹木の根元近くに本発明の根元保護具1を取り付けるとともに、その上側に従来型の防獣ネットNを設置している。このようにすれば、樹皮食害をより好適に防止することが可能となる。この点、例えば下側に本発明に係る根元保護具1を設置し、その上側に上記特許文献1〜3に記載の保護テープや防護ネットを設置するようにしてもよい。さらに、図10に示すように、本発明に係る樹木の根元保護具1を上下に複数段(図10においては2段)備えるようにしてもよい。   FIG. 9 shows another use state, in which the root protector 1 of the present invention is attached near the root of a tree, and the conventional anti-brain net N is installed on the upper side thereof. If it does in this way, it will become possible to prevent bark feeding damage more suitably. In this respect, for example, the root protector 1 according to the present invention may be installed on the lower side, and the protective tape and the protective net described in Patent Documents 1 to 3 may be installed on the upper side. Furthermore, as shown in FIG. 10, the tree root protector 1 according to the present invention may be provided with a plurality of stages (two stages in FIG. 10) up and down.

以上、本発明に係る樹木の根元保護具について、実施形態を例示して説明したが、本発明は、むろん上述の実施形態に限られるものではなく、本発明の趣旨を逸脱しない範囲で様々に形態等を変更することが可能なものである。   As mentioned above, although the embodiment was illustrated and explained about the root protector of the tree concerning the present invention, the present invention is not limited to the above-mentioned embodiment, and variously in the range which does not deviate from the meaning of the present invention. The form and the like can be changed.
