Threatened Plants have declined at an alarming rate in Australia over recent decades, pushing many species close to extinction. In response, a team from the Threatened Species Recovery Hub has identified the 50 species at greatest risk of extinction and the steps needed to halt and reverse their declines. Without action these species are really in trouble. About 30 of the species have less than 50 mature individuals left. Five of the species – slender-nerved acacia, Stirling Range dryandra, dwarf spider-orchid, Trigwell’s rulingua, and Bolivia Hill rice-flower each had less than five mature plants left in the wild at the end of 2020.
