4. Term of plan

This Interim Recovery Plan will operate from April 2003 to March 2008 but will remain in force until withdrawn or replaced. If the taxon is still ranked Critically Endangered after five years, the need to review this IRP or to replace it with a full Recovery Plan will be determined.

7. Taxonomic description

From Brown et al. (1998).

The winged membranous fruit is the main distinguishing feature of Lasiopetalum pterocarpum ms. The fruit has six to twelve elongated wings that usually consists of five large and several smaller wings. The fruit splits open when mature. The leaves are more obviously lobed than any other species of the genus Lasiopetalum. The bracteoles are linear and there are no petals or stipules. The apex of the style contains stalked star-shaped hairs.

Addendum

Wing-fruited Lasiopetalum (Lasiopetalum pterocarpum ms) 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.
