Addendum

Narrow-petalled Featherflower (Verticordia plumose var. pleiobotrya) Interim Recovery Plan 2003-2008

In adopting this plan under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), the Minister for the Environment and Heritage has approved the following modifications.

Critical Habitat
The plan identifies a broad area as critical habitat, including buffer zones of a set distance around known populations. The Threatened Species Scientific Committee does not necessarily believe that such an area qualifies as habitat critical to the survival of the species, as defined in the EPBC Act.

Recovery Criteria
For the purposes of reviewing this recovery plan under the EPBC Act, the Recovery Criteria are amended to read as follows:

Criteria for success: The number of individuals within populations and/or the number of populations have increased by 10% or more over the period of the plan's adoption under the EPBC Act.
Criteria for failure: The number of individuals within populations and/or the number of populations have decreased by 10% or more over the period of the plan's adoption under the EPBC Act.
