This paper describes the use of regularly spaced transect searches and standard capture–mark–recapture techniques to describe population structure, growth rates, survival and capture probability in a population of the pale-headed snake (Hoplocephalus bitorquatus). Within the red gum forests of our study site, we estimate pale-headed snake density at ~137 snakes/ha. We predict that pale-headed snakes reach sexual maturity after about four years and may live for up to 20.
This paper explores the reasons behind different mortality rates we have observed in some of our radio-tracked koala populations. It examines issues of inbreeding, genetics and disturbance, including such things as research activities.
We have been working with NSW OEH to develop a standardised field survey methodology that can inform on occupancy issues associated with the conservation and monitoring of Brush-tailed Rock-wallabies. Our initial focus has been in the Watagans and Curracabundi National Parks located in elevated hinterland areas of mid-coastal NSW.
