Isopogon ceratophyllus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Isopogon ceratophyllus faces severe population decline primarily due to habitat fragmentation and degradation from urban development and agricultural expansion across its limited range in southwestern Western Australia. The species is particularly vulnerable to altered fire regimes, as inappropriate burning frequencies can prevent successful regeneration and recruitment of new individuals. Climate change poses an additional threat through increased drought stress and shifting precipitation patterns that affect the Mediterranean-climate ecosystems this species depends upon.
Habitat
Isopogon ceratophyllus occurs in Mediterranean-climate shrublands and woodlands of southwestern Western Australia, typically growing in sandy or gravelly soils on slopes and flats. The species is adapted to fire-prone ecosystems and requires specific soil drainage conditions and seasonal rainfall patterns characteristic of the region's kwongan heathlands.
