The native vegetation of the Warragamba Special Area

The Warragamba Special Area covers around 260,000 hectares of remote, rugged bushland in the Blue Mountains, west of Sydney. It protects the catchment of Lake Burragorang, which is Sydney's major water source.

This report describes the distribution and composition of the Warragamba Special Area's native vegetation. It is the result of a comprehensive field survey, which found outstanding botanical diversity in the area. This includes:

  • over 1400 native plant species
  • 78 distinct vegetation communities
  • 75 eucalypt species - perhaps the highest diversity of eucalypts in the world
  • 26 plant species that are threatened in NSW, and 67 species that are on the Rare or Threatened Plants (ROTAP) list.

At least 37 per cent of the Warragamba Special Area shows moderate to high levels of disturbance, mainly in the flat and fertile lands to the east and south of the area. Around 190 introduced plant species were recorded, including infestations of serrated tussock, lantana, prickly pear and blackberry.
