The Geographe catchment is situated approximately 250 km south of Perth in the south west of Western Australia and covers approximately 2,000 km2.

The Geographe catchment supports a significant number of wetlands on the coastal plain however extensive clearing and drainage modification has led to the degradation or loss of many wetlands. One of the most important wetland areas is the Ramsar-listed Vasse-Wonnerup wetland system – a very large wetland, estuarine marshland and tidal floodplain area. Whilst much of the wetland has been retained in private ownership, the natural hydrology has been greatly altered by floodgates and drainage. Despite this, the wetland retains highly significant conservation values as an important waterbird habitat. Thirteen species of waterbirds breed on the Vasse-Wonnerup Wetlands including the largest regular breeding concentration of Black Swans in Western Australia.

The Geographe catchment is also very rich in biodiversity, with the world’s largest remaining tuart forest – the Ludlow Tuart Forest. It is estimated that only 37% of the catchment remains under native vegetation, with 69% of that vegetation occurring on private land.

The catchment supports 22 Declared Rare flora species and several Priority Listed flora species, and five Threatened Ecological Communities (TEC’s) – these are natural communities that exist here and nowhere else in the world!

The fauna within the catchment is also significant, however is under pressure from several factors including loss and fragmentation of habitat, decline of habitat quality through grazing and land degradation, the introduction of domestic and feral animals and changes to fire regimes.

Of particular significance, the Geographe catchment is home to one of the last viable populations of the Western Ringtail Possum, with an abundant population inhabiting the peppermint woodland from Busselton to Dunsborough. However as the townships of Busselton and Dunsborough grow, the possum’s primary habitat is under increasing threat from urban expansion.

Geographe Bay

The focal point of the Geographe catchment is the stunning Geographe Bay – home to the largest wooden jetty in the southern hemisphere, stretching almost 2 km out to sea.

Geographe Bay is believed to be an important calving and nursery area for the Hump Back Whale and a feeding ground for the Blue Whale. It also provides important spawning and nursery habitat for at least 13 commercially important fish species.
