Critical Habitat is defined under the Threatened Species Conservation Act 1995. They are areas of land that are crucial to the survival of particular threatened species, populations and ecological communities. This polygon layer contains Critical Habitat that has been declared and is now in operation. It does not include any recommendations (pending finalisation) nor does it include critical habitat where disclosing the location of critical habitat would expose the critical habitat to a significant threat eg. Wollemi Pine. The layer was last updated in 2014.
Areas of declared critical habitat under the Threatened Species Conservation Act 1995 have become the first Areas of Outstanding Biodiversity Value (AOBV) in New South Wales with the commencement of the Biodiversity Conservation Act 2016. The Critical Habitat layer will transfer to the new title in the future.

Note - Planning's Environmental Planning Instruments (EPI) Critical Habitat layer in the Planning SDE database (2016), as well as the Biodiversity Values (BV) Map, only list the Little Penguin Habitat at Manly. Both Mitchell's Rainforest Snail and Gould's Petrel Critical Habitat areas occur on NPWS Estate and are protected.
