Key threatening processes

A threat may be listed as a key threatening process under the NSW Biodiversity Conservation Act 2016 if it:

• adversely affects threatened species or ecological communities
• could cause species or ecological communities to become threatened.

Key threatening processes are managed through strategies developed under the Saving our Species program.

List of Key Threatening Processes

Some key threatening processes that pose threats to native plants and animals in New South Wales

Climate change

Changes to rainfall or temperature can threaten the survival of native species or ecological communities. Climate change also interacts with other threatening processes including fire and weeds by amplifying the impacts of these threats. In combination, these processes can significantly increase the risk of extinction of a threatened species and degrade the integrity of ecological communities.

These biodiversity and climate change online tools provide users with access to information on local impacts of climate change on biodiversity.

Weeds

Weeds such as lantana and bitou bush can compete with native plants for resources such as light, nutrients and space.

Weeds can aggressively invade areas and push out native plants and animals.

Pest animals

Introduced invasive animals like the European rabbit and red fox can compete with native animals for habitat and/or prey on them.

These pest animals can also damage native plants and degrade natural habitats, increasing pressure on the survival of native animals. See more information about pest animals.

Fire

Changes in fire patterns, such as an increase in the frequency of fire, can adversely affect or kill plants and animals.

Fire can also cause loss of habitat and changes to vegetation structure or composition.

Diseases

Exotic fungal infections, viruses and other pathogens can weaken and kill native species.

We have developed hygiene guidelines to help protect our biodiversity from Phytophthora cinnamomi, myrtle rust and amphibian chytrid fungus.

Saving our Species key threatening processes strategy

This strategy outlines the Saving our Species approach to managing key threatening processes, including developing specific strategies to manage priority threats.

Saving our Species is investing to improve threat management to reduce their impacts on biodiversity. This includes:

• Prevention actions to stop threats from entering New South Wales.
• Containment actions to contain a threat to a specific location.
• Strategic actions to improve management tools, guidance, and communications.
• Research actions to address gaps in our threat management knowledge.

Saving our Species is investing significant resources into on-ground management to protect threatened species and threatened ecological communities from key threatening processes at priority sites across New South Wales.
