South Coast NRM Print Return To Map
Located in the most western part of the South Coast NRM Region, the Kent Frankland includes the towns of Rocky Gully, Frankland, Cranbrook, Tambellup, Walpole and Broomehill. It contains the high rainfall, forested catchments flowing into the Nornalup and Irwin Inlets, with rainfall dropping off from in excess of 1200mm per annum at Walpole in the south, to about 450mm per annum at Broomehill in the north.

Vegetation types occurring in the Kent Frankland sub-region vary according to the soil type and annual rainfall. The soil types consist of several sand and loam mixes while the vegetation types vary from Wandoo and Yate woodlands near Tambellup, to Jarrah and Marri woodlands and Karri, Tingle and Jarrah forests between Walpole and Manjimup.

The Kent Frankland sub-region is quite biodiverse. Several endemic species of plants and animals occur in the area including Anthocercis sylvicola, sprawling spiky adenanthos (Adenanthos pungens subsp. effuses), Tingle species and the Gondwanan relictual Moggridgea spider. The region is also rich in aquatic life and with the formation of the Walpole-Nornalup Marine Park in May 2009 these regions will be protected in the future. Phytophthora dieback, feral animals, environmental weeds, land clearing and human disturbance threaten the biodiversity of this area.

Industry in the Kent Frankland sub-region is predominantly agricultural consisting of mostly cereal crops and grazing with some viticulture and silviculture. Perennial pastures are more predominant in this sub-region and are grown in rotation with wheat, barley, canola, oats and other crops. Salinity, water repellence, acidic soils and erosion are major threats to industry in the Kent Frankland sub-region. Tourism is another major industry with attractions such as the Tree-top Walk, Valley of the Giants, heritage buildings and wineries attracting thousands of people each year.

The Kent Frankland sub-region has significance to the indigenous Nyoongar people. This area is still significant and important for maintaining cultural customs. Middens, artifacts and fish traps can still be seen near the Walpole-Nornalup National Park.

South Coast NRM has funded several projects in the Kent Frankland sub-region. Funding has been provided to dryland farm forestry, biodiversity education and awareness raising, waterways, perennial pastures, Carnaby’s Black Cockatoo, soil health and sustainable agriculture.
