Water note 33 - The ecology of Wheatbelt lakes

Guidance
Information about Wheatbelt waterway and wetland systems and the impact of clearing native vegetation.
Last updated:

Land clearing and the replacement of deep-rooted perennial species with shallow-rooted annual cropping species in the Wheatbelt region of Western Australia has resulted in a reduction in water use by vegetation (evapotranspiration). This has in turn caused a rise in watertables and mobilisation of salt previously stored deep within the soil profile.
