This paper desribes 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/ha. We predict that 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


We have been working collaboratively with the NSW Office of Environment & Heritage to convene and deliver a short course in Occupancy Assessment & Monitoring. Our first course was delivered in Newcastle in June, 2018 and others are now planned in other regional centres. Assisted by OEH biometricians, the course offers an opportunity to better understand such things as key range / distributional parameters, how to design and implement occupancy-themed surveys and the utility of key occupancy metrics such as detection probability.
