Interim recovery plan no. 133

Department of Conservation and Land Management, WA, 2003

4. Term of plan

This Interim Recovery Plan will operate from May 2003 to April 2008 but will remain in force until withdrawn or replaced.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

Keighery, G.J. (1997). A new subspecies of Lambertia echinata (Proteaceae). Nuytsia 11 (2): 283-284.

Lambertia echinata subsp. occidentalis

Shrub, to 3 m tall, not lignotuberous, much branched at the base with many short vegetative branches and a few long erect floral branches. Vegetative leaves entire, 17-45 mm long, linear-lanceolate, apex pungent. Floral leaves on erect branches, a few immediately below the inflorescence with up to 5 points, the remainder either trifid (50-80%) or entire (20-50%), 12-30 mm long. Flowers yellow. Inflorescences crowded at ends of branchlets, 7-flowered. Floral bracts scarious, entire, brown, acute, narrowly obovate, 15-19 mm long. Perianth 23-26 mm long; lobes recurved, 3-5 mm long. Style yellow, 33-36 mm long.

Lambertia echinata subsp. echinata is a compact shrub to 1 m tall that has inflorescences of pink-red flowers on short branchlets in the main body of the plant. Both subspecies citrina and occidentalis have inflorescences of yellow flowers on short branchlets borne on long erect flowering branches to 3 metres tall above the main body of the plant. In Lambertia echinata subsp. citrina all vegetative and floral leaves have 3-5 rigid points, whereas L. echinata subsp. occidentalis has entire vegetative leaves and most floral leaves 3-pointed or entire. The floral bracts of subsp. occidentalis are longer, measuring 15-19 mm compared to 12-16 mm in subspecies citrina. There is also a difference in length between the floral leaves of all subspecies, 30-40 mm in subsp. echinata, 15-35 mm in subsp. citrina and 12-30 mm in subsp. occidentalis.

Addendum

Western Prickly Honeysuckle (Lambertia echinata subsp. occidentalis) 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.
