The effects of temperature and salinity on Acacia harpophylla (brigalow) (Mimosaceae) germination

Abstract

Acacia harpophylla F. Muell. (brigalow) used to naturally occur over a range of about 50 000 km2 in Queensland and New South Wales, Australia. Large scale clearing for agriculture has reduced the area to less than 20 000 km2 and it is estimated that 20-25% of vertebrate fauna living in brigalow communities will become locally extinct as a result of the current clearing induced loss of habitat. Some coal mining companies in central Queensland have become interested in providing habitat for the endangered bridle nail-tailed wallaby that lives in brigalow vegetation. However, there is little known about establishment techniques for brigalow on mine sites and other disturbed ground; an understan..
