摘要: We examined the abundance of arboreal marsupials in topographic fire refuges after a major stand- replacingcrown-fireforestecosystem.Wesurveyedtheabundanceofarborealmarsupialsacross48sitesinrainforestgullies burnt to differing extents by 2009 fires mountain ash (Eucalyptus regnans) forests Victorian Central Highlands, Australia.
