Project 4.4.11 Three Endangered species survive only in tiny populations in small areas of particular mountain ranges in Queensland: two mammals ranked in the top 20 Australian mammals most likely to go extinct (the carnivorous marsupials black-tailed dusky antechinus, Antechinus arktos, and silver-headed antechinus, Antechinus argentus) and a priority plant, the Bulburin macadamia nut tree (also called Bulburin nut). This project will use detection dogs together with other search methods to systematically survey all forest types throughout mountains where these Endangered species have been detected or are suspected to occur in order to establish locations of surviving populations, their vegetation types, fire histories, elevational ranges and climate change vulnerability.
