Conservation Status


Red List Category & Criteria: Near Threatened

(Despite the abundance of individuals and no evidence of decline, this variety has a small extent of occurrence well within the threshold for Endangered; its area of occupancy and number of locations also fall within these limits. It could become threatened if fires became more destructive in future, so Near Threatened seems to be an appropriate category)
