Hakea incrassata

Hakea incrassata is a woody shrub belonging to the Proteaceae family, native to Western Australia. Like other members of its genus, it produces rigid, often needle-like or terete foliage and woody fruits that persist on the plant, releasing seed after fire or plant death. Its flowers, typical of the Proteaceae, are small but clustered into showy inflorescences that attract insect pollinators, contributing to local pollination networks.

As a shrub layer species, it plays a structural role within its plant community, offering shelter and habitat complexity for invertebrates and small fauna.

The species occurs exclusively in Australia, restricted to shrubland habitats within a limited geographic range in the southwest of the continent. This region is characterised by nutrient-poor soils and a Mediterranean-type climate, conditions to which many Proteaceae, including Hakea species, are highly adapted.

The primary threat to Hakea incrassata is habitat conversion for annual and perennial non-timber crop agriculture, an ongoing pressure that reduces and fragments the shrubland habitat on which the species depends. Agricultural expansion in southwestern Australia has historically been a major driver of native vegetation loss, and continued land clearing for cropping remains a concern for this and related shrub species.

Conservation attention for Hakea incrassata is linked to broader vegetation protection efforts in Western Australia, including habitat conservation within remnant shrubland reserves and regulation of native vegetation clearing. Specific targeted recovery programs for this species are not extensively documented.

The population is currently assessed as stable, and the species is classified as Vulnerable. Continued monitoring of habitat loss trends will be important for maintaining this status over the longer term.
