WA Museum Records and Supplements | Updated 9 years ago

Introduction: The mammal survey of these reserves is part of an integrated survey of the vertebrate fauna of the Western Australian wheatbelt which is detailed in Kitchener (1976).

Mammals were collected on Yorkrakine Rock (YRR), East Yorkrakine (YER) and North Bungulla (NBR) Nature Reserves between 18-24 November 1974 and 11-16 May 1975. The 3 reserves were worked simultaneously with traplines 1-4 on YRR, traplines 5-7 on NBR and traplines 8-10 on YER. Sites where traplines were deployed are shown in Figs 2-4 in Muir (this report). The types of traps, manner of positioning small mammal traps in 'standard' lines and the bait used are described in Kitchener & Chapman (1976). The trapping effort is detailed in Appendix 1, and detailed descriptions of vegetation, soil and litter at each trapline are presented in Muir (this report). These data are summarised in Appendix 2. Weight was recorded in the field for all specimens, and all females were dissected in the laboratory and their reproductive organs examined in situ. In the annotated list below the numbers of animals captured at each trapline are indicated in parentheses. All specimens are in the Western Australian Museum with registration numbers M13139-13188 and M13698-99, M13705-13711.
