    Lake Cave in the south-west of WA is the last known cave within the Leeuwin-Naturaliste ridge with a permanent lake. It contains a diverse groundwater-dependent ecosystem, under threat from declining water levels. Without intervention, the cave's lake and its dependent fauna may disappear within two to four years.

    With funding from the State NRM program, the Augusta Margaret River Tourism Association Inc. is coordinating immediate efforts to stabilise water levels in the cave and to identify long-term options for the management of cave hydrology.

    This project aims to research and develop a recovery plan to save the lake in Lake Cave, and protect the associated large population of stygofauna (cave dwelling animals).

    Initial research will determine the source of the water for Lake Cave and whether the declining levels within the cave are a result of climate change or other external factors such as land use.

    Investment: $ 250 000
    Delivery organisation: Augusta Margaret River Tourism Association Inc.
    Project duration: June 2010 - March 2013
    Location: Lake Cave, 20 km south-west of Margaret River
