Riparian zones are the area of land around rivers, creeks, wetland and other waterways, and their condition has a strong influence on water quality, soil stability and habitat.
These types of landscapes deliver enormous environmental benefits, which is why Greenfleet includes their restoration in our revegetation strategy. In agricultural regions where waterways have been cleared, grazed or overtaken by weeds, banks are left vulnerable to erosion and the natural filtering benefits from native vegetation is lost. Reestablishing locally native plants helps rebuild those functions while also creating habitat and connectivity for wildlife.
Healthy riparian vegetation works like a living buffer. Plant roots help hold soil in place, reducing erosion and bank collapse. Grasses, shrubs and trees slow the movement of water across the land, allowing sediment, nutrients and pollutants to be filtered before they enter streams. Shade from trees helps keep water cooler, which benefits aquatic life such as fish, frogs and invertebrates.
