Status of the Vulnerable shrub Astrotricha crassifolia (Araliaceae) in Brisbane Water National Park, NSW: an update
- A resurvey (previously surveyed 2003–04) of the northern metapopulation of the listed Vulnerable shrub Astrotricha crassifolia (family Araliaceae) near Gosford, New South Wales, revealed six additional small subpopulations nearby, bringing to nine the total number, all in Brisbane Water National Park. While the stem count of the previously measured sites remained largely the same, the discovery of further subpopulations has increased the total known stem number to 1211 stems, with an area of occupancy of only 385 m2. The majority (nearly 80%) of these subpopulations are very small, directly adjacent to roads, and remain vulnerable to park management and maintenance practices. Astrotricha crassifolia is surviving due to its successful rhizomatous growth, but may not be reproducing from seed. This paper recommends some changes to management to reduce potential threats.
