The Manangatang Landcare Group covers a large area of approximately 190,000 hectares. It extends from Lake Tyrrell in the south to Annuello in the north. The group was officially formed in 1990 when a number of landholders approached the then Department of Conservation, Forests and Lands about subsidies for sand dune reclamation work to combat soil erosion. The Landcare Group quickly took on the role of coordinating and promoting other activities such as rabbit and weed control, revegetation and salinity control activities. Rabbit ripping campaigns conducted since 1997 have had 100% landholder participation.
