GREVILLEA SURVEYS
About Grevillea surveys
The Granite Belt has one nationally endangered grevillea species – black grevillea (Grevillea scortechinii subsp. scortechinii) with less than 1500 plants known to occur on the Granite Belt, the only place in the world this grevillea is found.
Through survey work we are increasing our knowledge about their population size and trends, distribution and threats. Members of the consortium have agreed to survey, promote and, where it occurs on public land, manage the habitat of this rare grevillea.
​
The aims of the project are to:
​
-
assess the size and distribution of population of Grevillea scortechinii subsp. scortechinii on the Granite Belt.
-
identify and document the impact of threats (eg weed invasion, plant removal, drought impacts and clearing).
-
undertake threat removal activities.
-
assess annual recruitment rates.
-
encourage land managers to mitigate threats through habitat management.
​
The project is being led by the consortium, and consortium members are participating in surveys and monitoring.
​
Please email gbwildflowers@gmail.com if you know the locations of additional grevillea plants on your property or would like to participate in these activities.
