Heath land is threatened due to the pressures of agriculture and especially urbanisation.
Species invasions from adjoining plant communities, have established and are completely changing the nature of heathlands. Woody weed invasion has become a major consideration of heathland management.
During the last 200 years over 90% of the heath land in north-east Hampshire has been lost.
Heath land is one of the rarest habitats in the world. It is even more threatened than the rain forest.
