A way to protect beaver burrows

Abstract

The invention discloses a method for protecting a beaver cave. The beaver cave includes an underwater outlet and a land inlet and outlet. A bionic dam is built on the river channel close to the beaver nest according to the surrounding terrain lines, so that the upstream of the bionic dam forms a still water area. The bionic dam is set with dead wood, branches and soil to make the river bypass the curved bionic dam to avoid impacting the beaver nest. The length of the bionic dam is determined according to the size of the beaver nest. ~1.0m, the height of dead wood branches is set 0.5~1.0m higher than the river water surface, and covered with soil. The invention can ensure the stability of the water level and create a stable aquatic ecological environment that protects the beaver channel and the beaver cave. After the bionic dam is completed, a still water area is formed to prevent the beaver nest from being washed away by too large and too fast water flow, and to prevent the beaver from building The dam body gnawed down too many trees, causing damage to the ecological environment.

Description

technical field [0001] The invention relates to beaver protection, in particular to a method for protecting beaver burrows. Background technique [0002] Beaver (Castor fiber): Mammalia rodents, belonging to Beaveridae, Beaver genus species, a total of 7 subspecies, is the largest medium-sized amphibious mammals in Rodentia. It is listed on the Red List of Threatened Species by the International Union for Conservation of Nature (IUCN) in 2008 and belongs to the national first-class protected animals. [0003] The body of beaver is fat, and there is no obvious difference between male and female. The body is covered with long and thick needle-like hairs and dense and soft fluff. The needle hairs are yellowish brown, and the base and fluff are brownish gray. Lighter than the back. The beaver has a short blunt head, small eyes, short neck, sharp incisor teeth, well-developed masseter muscles, short and wide limbs, short forelimbs, small feet, strong claws, no front webs, stron...

AI Technical Summary

Problems solved by technology

The establishment of dams and hydropower stations has led to the reduction of vegetation inundation in the area, resulting in soil erosion, riverbed subsidence, local diversion of rivers, and destruction of beaver caves

The migration route of beavers is blocked. In winter, due to water storage and power generation, the ice layer continues to rise, and the water even submerges the beaver caves, leading to the death of beavers in winter because they cannot settle down
