The Crooked River Catchment near Jeringong is a small but significant system, supporting a variety of agricultural enterprises such as dairy, beef and fidderculture. The catchment and its histories are also areas of significant natural beauty, a popular recreational destination and an important biodiversity corridor linking the Illawaris government with Seven Mile Beach National Park. The Crooked River SG has become a success story in New South Wales, marine estate management strategy. One of the aims of this strategy is to improve water quality by protecting creek and estuary foreshores. Over the past three years, the strategy has supported local landholders to protect over 80% of the Crooked River estuary foreshore. This aim to protect the water's edge from grazing stock allows the regenerating natural vegetation to filter runoff from surrounding paddocks and improve water quality. Improved water quality and the reestablishment of native vegetation communities such as Swamp Oak Forest, Salt Marsh and Mangrose will lead to a healthier and more resilient system. Five landholders, including Sydney Water Corporation, have now erected nine kilometres of fencing, protecting over 14 hectares of estuary, wet land and flood plain forest and planted over 10,000 trees. Protecting and enhancing these vegetation communities attracts wildlife, pollinators, improves fish breeding and provides shade and shelter for stock.
