Propagation, Research and Monitoring of Wavy-leaved Smokebush and Keighery's Macarthuria

Conospermum undulatum Lindl. and Macarthuria keigheryi Lepschi are listed as Threatened Flora in Western Australia, and listed as Vulnerable and Endangered, respectively, under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. Populations of both species will be impacted by clearing for the proposed new runway at Perth Airport.

The goal of this proposal is to successfully propagate, establish, secure and maintain new, viable population(s) of at least 250 individuals of Wavy-leaved Smokebush and at least 1160 individuals of Keighery’s Macarthuria within five years of undertaking any activity which results in an impact to the two plant species, or at least 347 individuals of Wavy-leaved Smokebush and at least 1513 individuals of Keighery’s Macarthuria by 1 December 2028, whichever occurs soonest. Achieving this goal will require: 1) new ecological and genetic research to inform establishment strategies; 2) development of propagation techniques and seed orchard establishment to produce plants for the new populations; 3) evidence of successful establishment of viable populations; and 4) contingency plans in the event that new population(s) have not successfully been established after the five-year period.
