Comparison of hairtube types for the detection of mammals

We compare detection rates of different species of mammals by three types o f hairtubes in both the mountain ash forests of the central highlands of Vi ctoria and a range of wet forest types at Tumut in southern New South Wales . The types of hairtubes were a small-diameter PVC pipe, a large-diameter P VC pipe and a newly constructed tapered hair funnel. Data were analysed for brown antechinus (Antechinus stuartii), bush rat (Rattus fuscipes), common wombat (Vombatus ursinus), swamp wallaby (Wallabia bicolor) and common and mountain brushtail possums (Trichosurus vulpecula and T. caninus). The mos t effective hairtube type (i.e. the one yielding the highest number of dete ctions) varied between species: small hairtubes for R. fuscipes, hair funne ls for Trichosurus spp., and large hairtubes for V. ursinus and W. bicolor. For A. stuartii, the most effective hairtube type differed between the two study regions (hair funnels in Victoria and small hairtubes at Tumut). Det ection by more than one hairtube type at a given plot was uncommon. Our fin dings have important implications for field surveys and how data gathered f rom such studies are interpreted. For example, if the aim of field survey i s to detect a wide range of species then several types of hairtubes may nee d to be deployed.
