Introduced grasses as a key threatening process - fact sheet

In September 2003 the NSW Scientific Committee made a final determination to list the 'invasion of native plant communities by exotic perennial grasses' as a key threatening process under the Threatened Species Conservation Act.

The Final Determination has been made in recognition of the increasing evidence that some perennial grass species have significant adverse impacts on biodiversity.

Introduced grasses can crowd out native plants, starve native animals, change bushfire patterns and more.

Which introduced grasses cause the most damage?
See which grasses are listed as a key threatening process, and find out about their effects on native plants.
