Description
本発明は、自生する水生植物を一時的に保管した後に、元の場所または代替場所に移植を行う、水生植物の保管・移植方法に関する。 The present invention relates to a method for storing and transplanting aquatic plants, in which a native aquatic plant is temporarily stored and then transplanted to the original place or an alternative place.
ため池や湿地などの水辺で建設工事を行う場合、希少な水生植物が生育していれば、その移植および保全が必要となる。しかし、希少な水生植物は、生育可能条件が複雑で、これを満足させる環境を人為的につくることが難しい。また、水生植物が希少な場合は、個体数が少なく移植可能な個体が限られ、さらに、遺伝的多様性保全を考慮すると他地域から移植することは避けなければならず、移植の失敗は地域生態系への大きなダメージとなる。 When constructing near water such as ponds and wetlands, if rare aquatic plants are growing, they need to be transplanted and preserved. However, rare aquatic plants have complicated growth conditions, and it is difficult to artificially create an environment that satisfies them. In addition, when aquatic plants are rare, the number of individuals is small and the number of transplantable individuals is limited. Furthermore, considering the conservation of genetic diversity, transplantation from other regions must be avoided, and transplantation failures are regional. It will cause great damage to the ecosystem.
水生植物の保全に関し、例えば、特許文献１には、自然環境下で水が継続的に供給される地点にミズゴケ湿原再生基盤を構築し、このミズゴケ湿原再生基盤にミズゴケを植え込むことによりミズゴケ湿原を再生してなるミズゴケ湿原再生方法が提案されている。特許文献１に提案されている方法は、想定される最高水位と最低水位とに基づいて、生育基盤の高さを調整するものであるが、大雨や少雨等により想定以上の水位変化が起こると、ミズゴケが流出、死滅等する可能性がある。

Have at least.
（採取工程）
自生する水生植物の少なくとも一部を、本発明で使用する浮遊栽培容器に入れる。
水生植物を採取するエリアは特に制限されず、例えば、貴重な水辺生態系が保全されているエリア、水辺での建設工事の工事対象エリア等が挙げられる。特に、工事対象エリアは、開発による自然環境への影響を緩和するというミティゲーションの観点から、本発明の保管・移植方法を適用することが好ましい。
(Collection process)
At least a part of the aquatic plants that grow naturally is placed in the floating cultivation container used in the present invention.
The area where aquatic plants are collected is not particularly limited, and examples thereof include an area where a valuable waterside ecosystem is conserved, an area targeted for construction work at the waterside, and the like. In particular, it is preferable to apply the storage / transplantation method of the present invention to the construction target area from the viewpoint of mitigation of mitigating the impact of development on the natural environment.
本発明で保管・移植する水生植物は、オオミズゴケ等の湿ったところに生える湿生植物、ミミカキグサ、モウセンゴケ等の浅い水際に生える抽水植物、ミズオオバコ等の水中に沈んだ状態で生育する沈水植物、イヌタヌキモやイチョウウキゴケ等の根が水底に固着せずに水面または水中を浮遊する浮遊植物などが挙げられる。 The aquatic plants to be stored and transplanted in the present invention include wet plants such as Ottelia alismoides that grow in moist places, water-extracting plants that grow in shallow water such as Utricularia bifida and Ottelia alismoides, and submerged plants that grow in water such as Ottelia alismoides. Examples include floating plants in which roots such as Ottelia alismoides and Ottelia alismoides do not stick to the bottom of the water and float on the surface of the water or in the water.
本発明で使用する浮遊栽培容器は、外部と水の交換をすることにより、外部の水を取り込み、容器内部に水生植物の生育環境を再現するものである。本発明で使用する浮遊栽培容器の材質は特に制限されないが、水に触れた状態で使用するため、錆びたり腐敗したりすることがない樹脂材料が好ましい。また、浮遊栽培容器を水に浮かばせる方法としては、比重１．０未満の材料を用いる、容器に中空の箇所を形成する、容器に浮きを取り付ける等の方法が挙げられる。 The floating cultivation container used in the present invention takes in water from the outside by exchanging water with the outside, and reproduces the growing environment of aquatic plants inside the container. The material of the floating cultivation container used in the present invention is not particularly limited, but a resin material that does not rust or rot is preferable because it is used in contact with water. Further, as a method of floating the floating cultivation container in water, a method of using a material having a specific gravity of less than 1.0, forming a hollow portion in the container, attaching a float to the container, and the like can be mentioned.
（保管工程）
水生植物を入れた浮遊栽培容器は、水生植物を採取したエリアの水上に浮かべて保管する。
本発明で使用する浮遊栽培容器は、内部に保管する水生植物の種類に応じて水位を調整する。例えば、浮遊栽培容器として底面に穴を設けた発泡スチロール箱等を用い、容器内部に入れる栽培基質や重り等により、所望の水位に調整すればよい。この際、栽培基質としては、自生地の土壌、赤玉土、乾燥ミズゴケ等を用いることができる。また、完全に水中で生息する水生植物を保管する場合は、浮遊栽培容器として植物が流出しない程度の大きさの網目を有するネットを用いることができる。本発明の浮遊栽培容器は、水に浮遊しており、外部と水の交換が可能であるため、水やり等の維持管理が不要である。
(Storage process)
Floating cultivation containers containing aquatic plants should be floated and stored on the water in the area where the aquatic plants were collected.
The floating cultivation container used in the present invention adjusts the water level according to the type of aquatic plants stored inside. For example, a styrofoam box or the like having a hole in the bottom surface may be used as a floating cultivation container, and the water level may be adjusted to a desired level by adjusting the cultivation substrate, weight, or the like to be placed inside the container. At this time, as the cultivation substrate, the soil of the own dough, Akadama soil, dried sphagnum moss and the like can be used. In addition, when aquatic plants that live completely underwater are stored, a net having a mesh size that does not allow the plants to flow out can be used as a floating cultivation container. Since the floating cultivation container of the present invention is suspended in water and can exchange water with the outside, maintenance such as watering is not required.
本発明の浮遊栽培容器は、自生エリアと同一水系の水上に浮かべることが好ましい。同一水系の水上に浮かべることで、水生植物を、採取エリアと生育環境の差が小さい状態で保管することができる。同一水系の水上に浮かべることが困難である場合は、ノッチタンクやタフブネ等を用いて仮設の水系に浮かべることも可能であるが、その場合は用いる水が移植対象とする植物の生育に適した水質であることを確認する。 The floating cultivation container of the present invention is preferably floated on water in the same water system as the native area. By floating on water of the same water system, aquatic plants can be stored in a state where the difference between the collection area and the growing environment is small. If it is difficult to float on the water of the same water system, it is possible to float on a temporary water system using a notch tank, tough bune, etc., but in that case, the water used is suitable for the growth of the plant to be transplanted. Make sure the water quality is good.
本発明の浮遊栽培容器は、水上に浮かべるものであるが、流出しないように、水の流れがない場所に浮かべるか、水底に打った杭等に固定することが好ましい。本発明の浮遊栽培容器は、水辺から１ｍ以上離れた水上に浮かべることが好ましい。浮遊栽培容器を水辺から離すことで、野生動物による食害、人間が管理の際に誤って刈ってしまうことや、人間や野生動物による踏圧を防ぎ、安全に保管することができる。本発明は、生育環境を再現した安全な環境下で水生植物を保管するため、保管中に水生植物は生育し、保管前と比べて水生植物を増やすことができる。 The floating cultivation container of the present invention floats on water, but it is preferable to float it in a place where there is no flow of water or to fix it to a stake or the like struck on the bottom of the water so as not to flow out. The floating cultivation container of the present invention is preferably floated on water at a distance of 1 m or more from the waterside. By keeping the floating cultivation container away from the waterside, it is possible to prevent feeding damage by wild animals, accidental cutting by humans during management, and treading by humans and wild animals, and it can be stored safely. Since the present invention stores aquatic plants in a safe environment that reproduces the growing environment, the aquatic plants grow during storage, and the number of aquatic plants can be increased as compared with that before storage.
保管中は、必要に応じて、遮光シートにより日射量を調整することが好ましい。日射を制限することにより、保管する水生植物に適した日射量に調整することができる。また、外部から飛散した種子等が発芽して、容器内部に雑草が繁茂することを防止することができる。 During storage, it is preferable to adjust the amount of solar radiation with a light-shielding sheet, if necessary. By limiting the amount of solar radiation, it is possible to adjust the amount of solar radiation suitable for the aquatic plants to be stored. In addition, it is possible to prevent seeds and the like scattered from the outside from germinating and weeds from growing inside the container.
（移植工程）
保管した水生植物の少なくとも一部を、移植する。移植は、一部のみ行い、残りは保管し続けることが好ましい。移植は、基本的に元の場所または新たに創出した水辺に行うが、工事対象エリア等では、土壌や水質などの環境条件が変化している可能性がある。そのため、移植した個体の定着が確認できるまでは、残りの個体を水上で保管し続けることが好ましい。移植した個体が生育不良、枯死等を起こした場合は、移植環境を再整備した後に残りの個体を移植するか、代替場所への移植を行う。
(Transplant process)
Transplant at least some of the stored aquatic plants. It is preferable to perform only a part of the transplant and keep the rest. Transplantation is basically carried out at the original location or at the newly created waterside, but there is a possibility that environmental conditions such as soil and water quality have changed in the construction target area. Therefore, it is preferable to keep the remaining individuals on the water until the colonization of the transplanted individuals can be confirmed. If the transplanted individual causes poor growth or death, transplant the remaining individuals after reorganizing the transplanting environment, or transplant to an alternative site.
