Provisional Checklist and Account of the Mammals of the London Borough of Bexley
PROVISIONAL CHECKLIST AND ACCOUNT OF THE MAMMALS OF THE LONDON BOROUGH OF BEXLEY Compiled by Chris Rose BSc (Hons), MSc. 4th edition. December 2016. Photo: Donna Zimmer INTRODUCTION WHY PROVISIONAL? Bexley’s mammal fauna would appear to be little studied, at least in any systematic way, and its distribution is incompletely known. It would therefore be premature to suggest that this paper contains a definitive list of species and an accurate representation of their actual abundance and geographical range in the Borough. It is hoped, instead, that by publishing and then occasionally updating a ‘provisional list’ which pulls together as much currently available information as can readily be found, it will stimulate others to help start filling in the gaps, even in a casual way, by submitting records of whatever wild mammals they see in our area. For this reason the status of species not thought to currently occur, or which are no longer found in Bexley, is also given. Mammals are less easy to study than some other groups of species, often being small, nocturnal and thus inconspicuous. Detecting equipment is needed for the proper study of Bats. Training in the live-trapping of small mammals is recommended before embarking on such a course of action, and because Shrews are protected in this regard, a special licence should be obtained first in case any are caught. Suitable traps need to be purchased. Dissection of Owl pellets and the identification of field signs such as Water Vole droppings can help fill in some of the gaps. Perhaps this document will be picked up by local students who may be looking for a project to do as part of their coursework, and who will be able to overcome these obstacles.
