Stirling Range Dyandra

Banksia montana is a woody shrub in the family Proteaceae, typically growing as a low, spreading plant with serrated, narrow leaves and cylindrical flower spikes composed of densely packed small flowers. Like other banksias, its flower spikes produce nectar that supports birds, mammals, and insects, and its woody seed-bearing follicles open in response to fire, making the species an integral part of fire-adapted plant communities. It plays a role in pollinator networks and contributes to post-fire regeneration cycles in its native habitat.

The species is endemic to the Stirling Range in southwestern Australia, where it occurs in isolated populations within montane forest and shrubland habitats, generally at higher elevations on rocky slopes and peaks.

Banksia montana is classified as Critically Endangered, with a declining population. A major threat is dieback caused by the introduced pathogen Phytophthora cinnamomi, a root-rot disease that kills susceptible plants and has severely affected Stirling Range vegetation. Altered fire regimes, including both overly frequent fire and fire suppression, disrupt the species' natural regeneration cycle, as plants require sufficient time between fires to mature and set seed.

Additional pressures stem from the restricted, fragmented nature of its populations, which increases vulnerability to localized disturbance events.

Conservation efforts include monitoring of remaining populations, hygiene protocols to limit the spread of Phytophthora, seed banking, and translocation trials aimed at establishing new or supplementary populations in suitable habitat. Research into disease resistance and habitat management continues.

Given the combined pressures of disease, altered fire patterns, and a naturally restricted range, the species' outlook remains precarious, with ongoing conservation intervention necessary to prevent further decline.
