Grevillea polybractea
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Grevillea polybractea faces severe population decline primarily due to habitat clearing for agricultural development and urban expansion across its limited range in Western Australia. The species is particularly vulnerable to frequent bushfires that prevent successful regeneration, while introduced weeds compete aggressively with seedlings for resources. Mining activities and road construction have further fragmented the remaining populations, reducing genetic diversity and limiting natural dispersal.
Habitat
Grevillea polybractea occurs in open woodland and shrubland communities on sandy soils, typically associated with lateritic breakaways and granite outcrops in the wheatbelt region of southwestern Western Australia. The species grows in areas with Mediterranean climate conditions, often in association with other endemic shrubs and low trees adapted to nutrient-poor soils.
