Grevillea eriobotrya

Declining

Overview

This member of the Proteaceae family is a woody shrub belonging to the diverse genus Grevillea, which is renowned for its distinctive flower clusters and specialised foliage. Like many of its relatives, it likely produces the toothbrush-like or spider-like flower heads characteristic of the genus, providing nectar resources for birds and insects within its shrubland community. As with other Grevillea species, it plays a structural and ecological role in the understory of its native habitat, contributing to the composition of shrubland vegetation and supporting local pollinator networks.

Grevillea eriobotrya is endemic to Australia, where it is restricted to shrubland habitat. Its range is limited, a common feature among Grevillea species that have adapted to specific soil types and microclimates within Australia's biogeographically distinct regions.

The species is classified as Critically Endangered, with a population trend that is decreasing. Two ongoing threats have been identified as primary drivers of this decline: the construction and maintenance of roads and railroads, which fragment habitat and directly destroy plant populations, and the expansion of annual and perennial non-timber crop agriculture, which converts native shrubland into cultivated land and reduces the extent of suitable habitat.

Conservation attention for this species is shaped by its Red List status, which typically involves monitoring of remaining populations and consideration of habitat protection within its restricted range. Specific large-scale recovery programs are not well documented in available records.

Given its Critically Endangered status, ongoing habitat conversion, and ongoing infrastructure development pressures, the species' trajectory remains concerning. Without effective mitigation of habitat loss, continued population decline is the expected outlook.

Grevillea eriobotrya is mainly threatened by the ongoing construction and maintenance of roads, which can destroy or fragment its habitat, as well as by the continued clearing of land for growing crops. These threats are currently ongoing rather than one-off events, meaning the pressure on the species' habitat is continuous rather than lessening.

Frequently asked questions

Why is Grevillea eriobotrya classified as Critically Endangered?
Grevillea eriobotrya is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Grevillea eriobotrya is mainly threatened by the ongoing construction and maintenance of roads, which can destroy or fragment its habitat, as well as by the continued clearing of land for growing crops. These threats are currently ongoing rather than one-off events, meaning the pressure on the species' habitat is continuous rather than lessening.
Where does Grevillea eriobotrya live?
Grevillea eriobotrya occurs in Australia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Grevillea eriobotrya?
The main threats to Grevillea eriobotrya are 2.1, and 4.1. The full IUCN-classified threat record for this species is detailed on the species page.
