The reserve is low lying and subject to periodic flooding. The island is the largest remnant of subtropical floodplain rainforest remaining in New South Wales. Floodplain rainforest is listed as an endangered ecological community under the Threatened Species Conservation Act 1995. Areas of wetland also occur within the reserve. The reserve contains important habitat for at least 7 species of threatened fauna including the Mitchell’s rainforest snail for which a separate recovery has been prepared.
The plan of management recognises the conservation and research values of the reserve. In order to minimise impacts to the sensitive habitat and threatened species in the reserve, visitor facilities will not be provided.
