Jim and Marian entered Trerieve into Countryside Stewardship, a DEFRA funded agri-environmental scheme, in 2001. This scheme has helped to provide capital to create the wildlife pond and traditional orchard, with varieties such as , and the wall that partly encloses it. It has also paid for rebuilding the Cornish hedges, stone faced earth banks, which not only provide shelter for the livestock, but also are a haven for all flaura and fauna.

Some fields have been taken out of arable production, and now contain a fantastic variety of coastal grasses and plants, such as Birds Foot Trefoil. Barley stubbles are also kept over winter to provide an attractive habitat for Cirl Buntings under this scheme”
