Map Viewing Service (WMS) of the dataset: Hamster — Terriers of 2019 in Grand East

2019 census of large hamster burrows occupied in Alsace in the plots of winter cereals (10 metres between two enumerators) and alfalfa (3 metres between two enumerators) to determine the status of the populations. The number of burrows identified according to this semi-exhaustive protocol validated in 2000 by the ONCFS is an index of abundance.本数据集涵盖2019年阿尔萨斯地区冬谷类作物田（两名调查员间距10米）及苜蓿田（两名调查员间距3米）内已被占用的大型仓鼠洞穴普查数据，旨在明确该种群的生存现状。依据2000年由法国国家狩猎与野生动物办公室（ONCFS）验证的半详尽调查方案所确认的洞穴数量，可作为该种群丰度的指示指标。
