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. 

A bit about us......

We have been working with community and all levels of government for more than 15 years now. We apply the highest ethical and professional standards, striving for scientifically objective and data-driven decision making in order to enable informed threatened species management and biodiversity conservation outcomes.



Current projects


Following on from our 2017 work, we have been engaged to undertake detailed koala hub assessments in the Tomago and Medowie areas, both of which were identified as potentially supporting small, extant population cells.
