Biodiversity

Printer-friendly version

Biodiversity in the Goulburn Broken Catchment encompasses a variety of ecosystems, including native vegetation communities, wetlands and waterways, and the associated plants, fungi, animals, microbes and genetic diversity they contain. Although terrestrial habitat is largely about native vegetation, it also includes rocky outcrops, fallen timber and soil.

Native vegetation is found across the Catchment as remnants, linear patches such as roadsides, revegetated sites and large reserves. Native vegetation types include the riverine forests in the Barmah and Lower Goulburn National Parks with associated Murray Pine and Buloke woodlands; spring-soak wetlands and rocky outcrops of the Strathbogie Ranges; box-ironbark forests; box-gum grassy woodlands; and wet forests interspersed with temperate rainforests to the south of the Catchment.

These native vegetation types provide important habitat for many species found across the Catchment, including many that are threatened. There are 2,750 native plant species, of which 337 or 13 per cent are threatened, and 493 vertebrates, of which 110 or 22 per cent are threatened (GB CMA 2010c). Some species that once occupied the Catchment are now extinct, such as the Eastern Bettong. Many threatened species now persist only in small patches of remnant habitat dominated by human influences (Bennett et al 2006).
