Anecdotal evidence from the last 18 months suggest that the 3 seasons of trapping and baiting may be having an effect on possum numbers and behaviour.
Twice per year we survey an area of West Cape Howe National Park. This happens over approximately 10 nights. While that data is yet to be analysed to produce a measure of possum density, we are seeing more possums, and their behaviour was markedly different in Autumn 2020. Many more possums were seen either close to, or on the ground.
With so many factors at play, such as seasonal influences (coming out of an exceptionally dry period) and different trees and shrubs in flower, it is far too early to say that the observed change in behaviour is solely related to the effects of baiting and trapping, however, it is very encouraging.
