Historical records of some mammals of the Whitby district and adjacent areas of Cleveland and the North York Moors

摘要

The following notes, collations of historical information and bibliography are presented as a background to monitoring historical trends in the mammal fauna of Whitby and adjacent areas of Cleveland and the North York Moors.The first attempt to plot the distribution of this region's terrestrial mammals at a 10km scale was undertaken between 1965 and 1970 and published by Corbet (1971), followed by Arnold (1978) and updated in 1984 and 1993. The first project to collate local records at a 1km scale was undertaken by the Yorkshire Naturalists' Union, its members and affiliated societies through the 1970s and early 1980s, the results appearing in Howes (1983). This was updated and had the interpretative advantage of plastic overlays including river systems and altitude in Delany (1985). The project was updated by the Yorkshire Mammal Group (YMG) after a 20 year gap and with the benefit of digital mapping technology in Oxford et al. (2007).
