Why is the water in Toolibin lake becoming salty?
Salinity. Natural vegetation has been removed in the past to make way for agriculture resulting in the water table rising and bringing salt from underground aquifers. This causes the soil and water systems in that area to become saline, which impacts on the health of Toolibin Lake’s fragile lake floor vegetation.
Why is Toolibin Lake so important?
Toolibin Lake has been recognised as providing important waterbird habitat, particularly for waterbird breeding, and meets the Ramsar criterion of supporting animals during critical stages in their life cycle. Up to 50 species have been observed at Toolibin Lake, which is one of the highest records of any inland south-west wetland.
Is Toolibin the only lake not completely saline?
Many other Wheatbelt wetlands formerly supported a vegetation community and ecosystem similar to that of Toolibin, but clearing for agriculture has resulted in most such sites becoming saline with a concomitant loss of emergent vegetation. Toolibin is the only major lake in the catchment that has not become completely saline.
