Description

G. brachystylis grandis typically grows to a height of 0.3 to 1 metre (1.0 to 3.3 ft), has non-glaucous branchlets and simple leaves 70 to 120 millimetres (2.8 to 4.7 in) long and 2 to 10 millimetres (0.08 to 0.39 in) wide. It produces irregular red inflorescence from August to September.[2]

Distribution

The shrub is endemic to a small area along the west coast of the South West region of Western Australia. It grows among medium to high trees and shrubland in loamy or sandy soils.[2] It occupies an area of approximately 10 square kilometres (2,471 acres) in an area in the Whicher Range[3] south of Busselton mainly in areas infested with Watsonia meriana var. bulbillifera and Juncus microcephalus.[1]

Conservation

The subspecies is only found in six fragmented locations, road reserves between areas cleared for agriculture. It species is listed as Critically Endangered in Western Australia in 2002.[3][4] In 2005 the estimated population following surveys was 176 plants.[3]

Translocation program

1000 seeds were collected from existing populations between 2009 and 2012. A total of 92 seedlings in 2012 and 172 in 2013 were planted at a secure site within a nature reserve close to the existing populations. The translocation worked well with 97 to 99% of the plants surviving after the first two years, 95% of them flowering and 80% bearing fruit.[5]
