Grevillea petrophiloides
Overview
Known commonly as pink pokers, this member of the Proteaceae family is a woody shrub that typically grows to around 2 metres in height, with finely divided, rigid leaves characteristic of the genus Grevillea. Its most distinctive feature is a dense, cylindrical inflorescence of pink to red flowers held on upright stalks well above the foliage, resembling a bottlebrush or poker. These flowers produce copious nectar and are pollinated primarily by birds, making the species a seasonal food source for honeyeaters and other nectarivorous fauna within its habitat.
The species is endemic to Western Australia, where it occurs within shrubland ecosystems, often on sandy or gravelly soils in the southwest of the state. Its range is naturally restricted to this region, and populations are patchily distributed across suitable remnant vegetation.
The species is classified as Vulnerable, with a decreasing population trend. Two ongoing threats are driving this decline: the construction and maintenance of roads and railroads, which fragment habitat and directly remove individual plants, and the conversion of shrubland to annual and perennial non-timber cropland, which eliminates habitat outright and isolates remaining populations into smaller, more vulnerable patches.
Conservation attention for the species centres on protecting remaining shrubland remnants from further clearing and managing roadside populations, which are particularly exposed to disturbance and edge effects from adjacent agricultural and infrastructure development. Ongoing habitat loss from land-use change continues to constrain the species' ability to maintain stable population numbers. Without measures to curb further clearing and fragmentation of remaining shrubland habitat, the population is expected to continue its decline.
Grevillea petrophiloides is mainly threatened by the ongoing construction and maintenance of roads and railways, which can destroy or fragment its habitat, as well as the continued clearing of land for growing crops. Both of these pressures are currently active and show no signs of stopping. Overall, these threats appear to be stable rather than clearly increasing or decreasing.
