SPECIES: Brachychiton guymeri — Blackwall Range Kurrajong
CLASSIFICATION: Critically endangered
The Blackwall Range Kurrajong is a small, handsome tree found only in a narrow stretch of dry rainforest and rocky slopes near Cooktown in far north Queensland. Growing up to 10 metres tall, it bears glossy green leaves and striking bell-shaped pink to red flowers that add a splash of colour to the rugged landscape. Like its better-known relatives, it stores water in its swollen trunk and roots — an ingenious adaptation to the dry tropical climate.
This rare species is critically endangered due to its extremely limited range and the ongoing loss of habitat from clearing, grazing, and altered fire regimes. Invasive weeds and changing rainfall patterns also threaten its survival. Conservation efforts are focused on protecting remnant populations and managing fire to preserve its unique habitat. Safeguarding this resilient little tree ensures the Blackwall Range continues to bloom with one of Queensland’s most distinctive native treasures.
