Landowners near Devon's River Dart are being offered grants from the Devon Wildlife Trust (DWT) to improve water quality and river habitat.
The scheme is open to those with more than one acre of land
The trust is working with farmers, advising them on ways to manage their land to the benefit of the river.
The charity is supporting the work by installing remote cattle watering points, putting in stock proof fencing and maintaining guttering.
Now it has accepted the first grant applications from local landowners.
The part EU-finded scheme is open to anybody who owns, manages or rents more than one acre of land within the Dart catchment.
Daniel McGonigle from the Trust said: "Maintaining good river quality has benefits for both wildlife and economic activities like fishing and farming.
"It's good to be on the ground working with farmers and land owners to help them to protect their natural resources so that the Dart will go on being a special river into the future."
