Alloxylon pinnatum

Alloxylon pinnatum, commonly known as the Dorrigo waratah, is a tall evergreen tree in the family Proteaceae, reaching heights of up to 30 metres in mature rainforest stands. It produces striking clusters of red, tubular flowers arranged in terminal racemes, a display typical of the genus Alloxylon and characteristic of the broader Proteales. These flowers attract nectar-feeding birds, which serve as pollinators, making the species a contributor to rainforest pollination networks.

Its leaves are often lobed or pinnately divided in juvenile stages, becoming more entire with maturity.

The species is endemic to Australia, restricted to subtropical and tropical moist lowland and highland forests in a limited range spanning parts of northern New South Wales and southern Queensland. It typically grows within well-developed rainforest canopies, favoring fertile, moist soils.

Its population is in decline, and the species is currently classified as Vulnerable. The principal threats stem from land conversion for annual and perennial non-timber crops, which fragments and removes suitable rainforest habitat, and from the ongoing pressure of invasive non-native species, which can outcompete seedlings, alter forest structure, or introduce disease. Both threats are considered active and continuing.

Conservation efforts include protection of remaining habitat within designated forest reserves and national parks in its range, along with monitoring of known populations. Restoration plantings and control of invasive species in some protected areas provide additional support, though range-wide coordinated recovery programs remain limited.

Given continuing habitat pressure and the species' naturally restricted distribution, the outlook remains cautious. Without expanded habitat protection and effective invasive species management, the population is expected to continue its gradual decline.
