The Little Ouse Headwaters Project (LOHP) was set up in 2002 by local residents to promote conservation and enjoyment of the fenland habitats bordering the upper reaches of the River Little Ouse, which lies on the Norfolk-Suffolk border.
The area also include parts of the Blo' Norton and Thelnetham Fen Site of Special Scientific Interest (SSSI).
The project is a registered charity and holds monthly work parties to manage the habitat of the various fens.
[2] After the Second World War the course of the River Little Ouse was over-deepened which led to the drying-out of the surrounding fen and the conversion of much of the land to arable use.
[3] The ending of traditional management practices and the lowering of the water table also led to increased dehydration which caused a decline in the bio-diversity of the area.
