An ecological study of Goose Island, British Columbia, with special reference to terrestrial mammals

University of British Columbia

A study of mammals on the Goose Island, British Columbia, was conducted in the summer of 1948. This group of islands represents a well isolated unit typical of many outer fringe islands along the coast. Over and above the qualitative examinations of the fauna, studies were undertaken to obtain some quantitative information upon the ecological distribution of terrestrial mammals. The terrestrial mammalian fauna was represented by three species of small mammals, Peromyscus maniculatus. Microtua longicaudus and Sorex obscurus. Two species of bats also occurred, Lasionycteris noctivagans and Myotis yumanensis. A species of Castor once inhibited the islands. Based on a snap trap procedure the relative abundance of Peromyscus, Microtus and Sorex was determined in four habitats occupied by all three species. The floral composition of these habitats was determined and reasons for the observed distributions postulated. The extent and nature of eight additional habitats have been included as well as notes on pelagic mammals, Myotis, Lasionycteris and Castor.
