Interim recovery plan no. 142

Department of Conservation and Land Management, WA, 2003

4. Term of plan

This Interim Recovery Plan will operate from June 2003 to May 2008 but will remain in force until withdrawn or replaced.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.

Eremophila verticillata is a low spreading shrub up to 0.8 m high and 1 m diameter, emitting a strong, slightly offensive odour. Branches terete, erect or spreading, non-tuberculate, sparsely to densely hirsute. Leaves sessile, in whorls or 3, appressed to branches, green to purplish, fleshy, narrowly oblong, 2.5-6 x 1 mm, obtuse, hirsute on adaxial surface, obscurely glandular-papillose on abaxial surface. Flowers 1 per axil, sessile. Sepals 4, valvate, green, subequal, linear to lanceolate, (1)1.5-5 x 0.3-1 mm, acute, outside surface glabrous or glandular-pubescent, inside surface glandular-pubescent. Corolla (5)8-11 mm long, violet, but inside of tube white on lower side and purple spotted, 2-lipped, outside surface pubescent, hairs consisting of short glandular and longer eglandular ones, lower half of medial lobe of lower lip villous, with hairs extending down tube below lobe; lobes obtuse, medial lobe of lower lip dilated, emarginate. Stamens included, glabrous. Ovary ovoid, c. 1.5 x 0.5 mm, green, bilocular with one ovule per loculus, hirsute; style glabrous. Fruit dry, ovoid, 2-3 x 1-2.5 mm, beaked and slightly separated into two at apex, hirsute with short glandular and longer eglandular hairs. Seed unknown.

Addendum

Whorled Eremophila (Eremophila verticillata) 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.
