Grevillea crowleyae

Declining

Overview

Grevillea crowleyae is a shrub in the family Proteaceae, a group of flowering plants known for producing distinctive flower clusters that attract nectar-feeding birds and insects. Like many of its relatives, it likely bears the characteristic toothbrush- or spider-like inflorescences typical of the genus, along with rigid, often finely divided foliage adapted to nutrient-poor soils. As a nectar producer, it likely contributes to supporting pollinator populations, including birds and invertebrates, within its native forest habitat, and its foliage and seed may provide food or shelter for small fauna.

The species is endemic to Australia, where it occurs within forest ecosystems. Its known range is considered restricted, consistent with its classification as Endangered under IUCN criteria.

The primary threats to Grevillea crowleyae are habitat disturbance and loss linked to road and railroad development, which fragments populations and can directly destroy individual plants, and the ongoing expansion of annual and perennial non-timber crop agriculture, which converts native forest into cultivated land and reduces the extent and quality of suitable habitat. These pressures are ongoing rather than historical, and their cumulative effect is a continuing decline in population size and range.

Conservation attention for threatened Grevillea species in Australia typically includes habitat protection within reserves, monitoring of wild populations, and consideration of impacts during infrastructure and agricultural planning approvals, though species-specific measures for this taxon are not well documented in available records.

The population trend is currently decreasing, and without effective mitigation of habitat clearing and fragmentation, the species' conservation outlook remains concerning.

Grevillea crowleyae faces ongoing pressure from road and railway construction, which can fragment or destroy its habitat, as well as from the clearing of land for crop farming. These threats are currently ongoing and appear to be stable rather than increasing or decreasing based on available information.

Frequently asked questions

Why is Grevillea crowleyae classified as Endangered?
Grevillea crowleyae is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Grevillea crowleyae faces ongoing pressure from road and railway construction, which can fragment or destroy its habitat, as well as from the clearing of land for crop farming. These threats are currently ongoing and appear to be stable rather than increasing or decreasing based on available information.
Where does Grevillea crowleyae live?
Grevillea crowleyae occurs in Australia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
