TEC Description
The community is known from heavy fertile soils of the southern
Swan Coastal Plain south of Dardanup. It consists largely of
Corymbia calophylla (marri) forests and woodlands. Eucalyptus
marginata (jarrah) is also common in the tree layer. This
community is often waterlogged and supports wetland dependent
species. Common understorey species include Acacia extensa
and Lomandra purpurea (purple mat rush). The community is also
known as “floristic community type 1b” as originally described in Gibson N., Keighery B.J., Keighery G.J., Burbidge
A.H. and Lyons M.N. (1994) “A floristic survey of the southern Swan Coastal Plain” (unpublished report for the
Australian Heritage Commission prepared by the Department of Conservation and Land Management and the
Conservation Council of Western Australia (Inc.)).
Distribution
The community is restricted to small isolated remnants, around Dardanup and south to Carbunup.
Department of Biodiversity, Conservation and Attractions (DBCA) Region: South West
DBCA Districts: Busselton and Wellington
Local Government Authorities: City of Busselton, Shires of Capel and Dardanup.
Habitat Requirements
The southern marri woodlands are restricted to alluvial soils of the Pinjarra Plain. They occur low in the landscape
on the margins of wetlands confined to the Busselton Plain (Swan Coastal Plain).

Indigenous Interests
An Aboriginal Sites Register is kept by the Department of Indigenous Affairs. According to the register a significance
site occurs close to occurrences of the community. The South West Aboriginal Land and Sea Council (SWALSC), an
umbrella group, covers the areas in which the community occurs. Traditional owner group: Wadandi.
Conservation Status
Listed as vulnerable under WA Minister Environmentally Sensitive Areas list in policy.
Threatening Processes
The major threats to the community are land clearing, weed invasion, too-frequent fire, dieback disease caused by
Phytophthora species, grazing by introduced or native species, recreational impacts and hydrological change.
Recovery Plan
A recovery plan is recommended for the community. Priority recovery actions include monitoring impacts of fire,
weed control, dieback assessment and control, track management, and rabbit control.
