Warren overview map


The Warren catchment is located in the south west corner of Western Australia, approximately 250 km from Perth. Its catchment area covers approximately 9500 km2 and lies mostly within the boundary of the Shire of Manjimup with a small portion within parts of the Boyup Brook, Kojonup, Nannup, Cranbrook and Bridgetown-Greenbushes Shires.  The catchment includes four towns, Manjmup, Pemberton, Northcliffe and Walpole and five smaller settlements. The town of Manjimup being the main regional centre.

Approximately 70% of the catchment is within Department of Parks and Wildlife estate. The remaining area within the catchment has generally been cleared for agriculture, horticulture and a small amount of residential and semi-rural properties.



With much of the Warren catchments area being within State Forest and conservation estate, only approximately 20% of the catchments area supports a population of approximately 10,000 and a mix of industrial, urban, rural and semi-rural land uses. The towns vary in size with the major urban centre being Manjimup. Read more.



The Warren catchments area encompasses the catchments of the Donnelly, Warren, Gardner, Shannon, Weld and Deep River Systems as well as the Lake Muir Byenup system. The Warren River is the major river, incorporating the Tone, Perup and Wilagarup Rivers. The catchments area contains some highly prized natural assets, in particularly its highly valued waterways and iconic biodiversity. Read more.        


Although less than 20% of the catchments area is private property, there are approximately 1800 rural properties in the area. This land produces a diverse range of products ranging from vegetable crops and sub-tropical fruit in the higher rainfall zones to dryland crops such as canola and barley in the upper catchment (dryer) zone. The diverse natural environment attracts many visitors to the area throughout the year. Read more.



Climate change and the catchment

Workshops were conducted across the SW NRM Region between March to June 2014 and explored how community members and NRM professionals define their catchment; what changes they have noticed; and how they believe a changing climate will affect their lifestyles, livelihoods and the landscapes they live in. The full report can be found here. Through the discussions of the workshops, changes to the systems beyond climate change were raised and included in the visual representations found here. It was important to capture the discussion of the whole system and its values.
