A Recovery Plan under the Environment Protection and Biodiversity Conservation Act 1999 (C’wlth), based on an Action Plan (Action Plan No. 25) prepared for the species under the Nature Conservation Act 1980 (ACT)
The Nature Conservation Act 1980 (ACT) establishes the ACT Flora and Fauna Committee with responsibilities for assessing the conservation status of ACT flora and fauna and the ecological significance of potentially threatening processes. Flora and Fauna Committee assessments are made on nature conservation grounds only and are guided by specified criteria as set out in its publication Threatened Species and Communities in the ACT, July 1995.
In making its assessment of the Ginninderra Peppercress, the Committee concluded that it satisfied the following criteria.
1.2 The species is observed, estimated, inferred or suspected to be at risk of premature extinction in the ACT region in the medium-term future, as demonstrated by:
1.2.4 Severely fragmented distribution for a species currently occurring over a small range or having a small area of occupancy within its range.
The Australian Government Minister for the Environment and Heritage determined that L. ginninderrense would be listed as a vulnerable species under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act). The criteria applied were:
- low population size (2000 mature individuals);
- restricted area of occupancy (2.7 km2); and
- no evidence of continuing decline.
The EPBC Act provides that the Commonwealth Minister may adopt a recovery plan made by a State or self-governing Territory, with modifications as specified. Adoption of such a plan requires that it have the contents of a recovery plan as specified by section 270 of the EPBC Act.
