Further evidence for the precipitous decline of endemic rainforest frogs in tropical Australia*

Abstract

In Queensland, Australia, severe declines or possible extinctions have been reported for a number of stream-dwelling frogs, all in montane rainforest environments (Covacevich and McDonald 1993). The declines have followed a distinctive geographic pattern, commencing in southern Queensland in the late 1970s (Czechura and Ingram 1990) then progressing to central Queensland (McDonald 1990) and finally to north Queensland in the mid-1980s (Richards et ai. 1993).
