NDFF Atlas of the dutch mammals 1992
收藏资源简介：
Many people contributed to the atlas of the occurrence of land mammals (and 2 species of seals) common to the Netherlands. The observations were made from 1970 to 1988. The Inspectorate Nature Conservation (Natuurbehoud) from the Dutch Forestry Commission (Staatsbosbeheer) has developed forms for most observations. Observations are reported on a scale of an hour plot or atlas plot, a grid cell of 5 square kilometres. Several species experts and species authors validate observations with information from that period as a reference. Dataset available via https://www.ndff.nl/english / serviceteamndff@natuurloket.nl Positive observations without zeros. 25,438 records (March 2018) https://www.ndff.nl/overdendff/validatie/protocollen/17-005-atlas-van-de-nederlandse-zoogdieren-1992/
