Dataset Direct Download Service (WFS): Hamster — Terriers of 2003 in Alsace

2003 census of large hamster burrows occupied in Alsace in winter cereal plots (10 metres between two enumerators) and alfalfa (3 metres between two enumerators) for population status. The number of burrows identified according to this semi-exhaustive protocol validated in 2000 by the ONCFS is an index of abundance.2003年针对阿尔萨斯地区冬谷类作物田（两名调查员间距为10米）与苜蓿田（两名调查员间距为3米）内已被占用的大仓鼠（large hamster）洞穴开展普查，以评估其种群现状。依据2000年由法国国家狩猎与野生动物办公室（ONCFS）验证的半穷尽式调查方案所确定的洞穴数量，可作为该物种种群丰度的指标。
