About the plan
Conostylis micrantha was declared as Rare Flora in September 1987 under the Western Australian Wildlife Conservation Act 1950. It currently meets Red List category Vulnerable under World Conservation Union (IUCN) criterion D1 (IUCN 2000). C. micrantha is listed as Endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). Four populations have been discovered within a Nature Reserve since 1996. The habitat of these populations is subject to low levels of weed invasion, and low intensity impact from rabbits. The main threats include edge effects, weeds, road, railway and firebreak maintenance, rabbits and inappropriate fire regimes.
An Interim Recovery Plan was developed for this species in 1996 (Holland et al. 1996). Information collected since that plan was completed has been incorporated into this plan and this document now replaces Holland et al. (1996).
Conostylis micrantha is a small, tufted perennial herb to 30 cm in diameter with yellow-cream flowers that turn a brick red colour with age. The leaves are 24 - 31 cm long and circular in cross-section, with a few spreading, white hairs 3 to 9 mm long on the lower margins. The flowers are held on stems 5 to 13 cm long, with a hairy papery bract 3 to 8 mm long halfway up the stem. The tubular flower is 5 to 7.5 mm long, and divides into six lobes that are cream inside and golden yellow outside (Brown et al. 1998).
