Moorland or moor is a type of habitat found in upland areas in temperate grasslands, savannas, and shrublands and the biomes of montane grasslands and shrublands, characterised by low-growing vegetation on acidic soils. Moorland today generally means uncultivated hill land (such as Dartmoor in South West England), but also includes low-lying wetlands (such as Sedgemoor, also South West England). It is closely related to heath, although experts disagree on the exact distinction between these types of vegetation. Generally, moor refers to highland and high rainfall areas, while heath refers to lowland zones which are more likely to be the result of human activity. Moorland habitats are found mainly in tropical Africa, northern and western Europe, and South America. Most of the world's moorlands are diverse ecosystems. In the extensive moorlands of the tropics, biodiversity can be extremely high. Moorland is also related to tundra (where the subsoil is permafrost or permanently frozen soil), appearing as the tundra and the natural tree zone. The boundary between tundra and moorland constantly shifts with climatic change.
