Survey and Evaluation of Wildlife Resources in Heilongjiang Huzhong National Nature Reserve
Regular survey and continuous monitoring of wildlife resources are important means for biodiversity maintenance,assessment and management.In order to further clarify the basic situation and the changing characteristics of populations of wildlife resources in the Heilongjiang Huzhong National Nature Reserve,a winter survey of veterinary animals and forest-dwelling birds was carried out from November to December in 2022.The footprint chain was adopted as a statistical index for the indirect population survey of animals,and the sample strip method was utilized to estimate the number of populations.The habitat quality was evaluated in terms of habitat fragmentation,conservation status,and development trends.The results showed that 12 species of beasts from 3 orders and 7 families were found in the 56 sample strips,and the populations were quite large in number and distribution,with siberian musk deer(Moschus moschiferus),sable(Martes zibellina),wolverine(Gulo gulo),moose(Alces alces)being the more prominent ones;2 species of forest-dwelling birds from 1 order and 1 family were found,including black-billed capercaillie(Tetrao urogalloides)and hazel grouse(Tetrastes bonasia).The habitat quality of siberian musk deer,wolverin,moose and sable was good,and the habitat quality of mountain hare(Lepus timidus),wapiti(Cervrs canadensis)and black-billed capercaillie was poor.Based on the results of the survey analysis and evaluation,targeted management countermeasures such as the establishment of a sound scientific research and monitoring system and the restoration of wildlife habitat connectivity have been proposed,so as to realize a comprehensive improvement in the level of biodiversity monitoring and protection and management capacity of the nature reserves.
