Habitat loss

There are very few native environments in Australia that have not been affected by human activities. Natural habitats have been destroyed, fragmented and modified, resulting in widespread changes to the distribution and abundance of native plants and animals.

Much of NSW is affected by some form of land degradation. In many places, particularly in urban and agricultural areas, only isolated remnants of habitat remain. These are often under considerable stress from human activities.

Bushrock removal
Bushrock is sometimes taken from bushland areas and used to decorate gardens. This robs many native plants and animals of habitat, and it has been declared a 'key threatening process' in NSW. Find out more.

Clearing of native vegetation
Since colonisation, a huge proportion of the state's original native vegetation has been cleared, thinned or substantially or significantly disturbed. This has far-reaching ecological impacts, and has been declared a 'key threatening process'.

Removal of dead wood
Dead wood, trees and logs are often cleared to 'tidy up' the landscape, but they provide vital habitat for many plants and animals. Find out more.

Subsidence due to longwall mining
Longwall mining - an underground coal mining technique - can cause the land above the mined-out coal seam to destabilise and collapse. This can change the habitat of many species and ecological communities.

Loss and/or degradation of sites used for hill-topping by butterflies - key threatening process listing
Many species of butterfly rely on hilltops for mating, but these sites are often used for housing, communications and other purposes. The NSW Scientific Committee has declared the loss of hill-topping sites to be a 'key threatening process' in NSW. Find out why.
