Catlins FMU
The Catlins Freshwater Management Unit (FMU) contains many unmodified river, coastal and estuarine ecosystems, including an extensive spread of indigenous land cover. The landscape is made up of low ridges running in a north-west/southeast direction which supports the native forest and high-producing grasslands.
The headwaters and native vegetation have been left intact, which helps to maintain good water quality. However, cleared valleys allow intensive farming, and some of the parameters we monitor indicate that water quality is degraded. We monitor water quality and ecology for the Catlins River, Owaka River, Maclennan River and the Tahakopa.
