Rapid Ecological Assessment Brook (North) Island and Eva Island

Abstract

This report presents the findings of rapid ecological assessments conducted on Brook (North) Island and Eva Island in the northern Great Barrier Reef. The study focuses on updating information on the distribution, condition, and ecological context of Pisonia grandis forests, alongside identifying key biodiversity values and threats present on the islands. Using a rapid survey approach, the assessment provides a snapshot of island condition, including potential stressors affecting Pisonia vegetation, with particular attention to the presence of soft scale (Pulvinaria urbicola) and other influencing factors such as weeds and environmental disturbance. The surveys also document broader ecological values to support understanding of habitat condition and ecosystem function. The findings are intended to inform management by improving understanding of current Pisonia forest condition and associated threats, providing an evidence base to support the protection and enhancement of island ecosystems within the Great Barrier Reef World Heritage Area. This work forms a key deliverable under the Restoration of Reef Islands Project, delivered through the Reef Joint Field Management Program (Great Barrier Reef Marine Park Authority and Queensland Parks and Wildlife Service) in partnership with e Girringun Aboriginal Corporation , and Aestra as the environmental delivery partner, and funded by the Australian Government’s Reef Trust. The project aims to support the rehabilitation, enhancement, and long-term resilience of island ecosystems within the Great Barrier Reef World Heritage Area.
