Moorland or moor is a type of habitat, in the temperate grasslands, savannas, and shrublands biome, found in upland areas, characterised by low-growing vegetation on acidic soils and heavy fog. Moorland nowadays generally means uncultivated hill land (such as Dartmoor in South West England), but the Old English mōr also refers to low-lying wetlands (such as Sedgemoor, also SW England). It is closely related to heath although experts disagree on precisely what distinguishes the types of vegetation. Generally, moor refers to highland, high rainfall zones, whereas heath refers to lowland zones which are more likely to be the result of human activity.
Moorland habitats are most extensive in the neotropics and tropical Africa but also occur in northern and western Europe, Northern Australia, North America, Central Asia, and the Indian subcontinent. Most of the world's moorlands are very diverse ecosystems. In the extensive moorlands of the tropics biodiversity can be extremely high. Moorland also bears a relationship to tundra (where the subsoil is permafrost or permanently frozen soil), appearing as the tundra retreats and inhabiting the area between the permafrost and the natural tree zone. The boundary between tundra and moorland constantly shifts with climate change.
John o' Groats (Taigh Iain Ghròt in Scottish Gaelic) is a village in the Highland council area of Scotland. Part of the county of Caithness, John o' Groats is popular with tourists because it is generally regarded as the most northerly settlement on the island of Great Britain, although this is not a claim made by its inhabitants and is in fact false. It is however one end of the longest distance between two inhabited points on the island of Great Britain, Land's End being the other. (The most northerly point on the island of Great Britain is nearby Dunnet Head). (ND202767)
