Commons rights used to be attached to particular plots of land (or to particular hearths). Grazing of commoners' ponies and cattle is an essential part of the management of the Forest, helping to keep the heathland, bog, grassland and wood-pasture habitats and their wildlife in good shape.This ancient practice came under pressure as the rising house prices in the area stopped local commoning families from moving into new homes which have the rights attached which meant the next generation could not become commoners until their parents passed on the house and rights. Those rights are now dissasociated. Efforts by the CDA, Verderers and associated bodies mean there is a burgeoning economy in the New Forest and a chance for some commoners to earn well above the minimum wage - and additional help for their farming interests. This will help the commoners continue to preserve the Forest.
