Threatened mammal population census at Scotia
One of the distinguishing features of our approach to conservation is that we regularly measure the ecological health of our properties using the best available science. These data-based metrics help us continually improve our land management strategies and provide investors (donors) with information about their ecological return on investment.
At Scotia Wildlife Sanctuary, our ecological health framework includes regular population estimates of threatened mammals using a range of survey techniques and statistical analysis. The latest results are now in, confirming the critical importance of Scotia for several endangered species
The Bridled Nailtail Wallaby population is estimated at more than 1,700 animals(an increase from last year), representing around 80% of the Australian population.
The Burrowing Bettong population is estimated at 733 animals (a modest decline reflecting dry conditions).
The Bilby population is estimated at more than 1,000 animals (also an increase from last year), representing around 10% of the Australian population. See graph below.
