摘要

Southwestern Australia is a major genetic resource for the Proteaceae, with about 620 endemic species and subspecies. Their habitats are under threat in some areas from land clearing. The spread of Phytophthora cinnamomi, to which this family is particularly susceptible, has reached epidemic levels in the southern sand plains. Potential threats include increased fire frequency, invasion of post-fire vegetation by herbaceous weeds, reduced annual rainfall and canker diseases. The levels of pollinators, granivores and herbivores, and burning in spring, are at present no cause for concern.
