Label	Definition
Bare Earth Or Grass	Land that can be interpreted as having a natural surface cover which is not classified vegetation and is not associated with other themes.
Coniferous Trees	An area of cone-bearing trees (for example, yews, pines, firs, and larch), where the trees are generally spaced not more than 30m apart.
Heath	An area of vegetation made up of a combination of heather or bilberry with very few trees or bushes.
Made Sealed	A manmade surface that consists of a solid material that is bonded (i.e. is not loose).
Made Unknown	A manmade surface that may be either sealed or unsealed.
Made Unsealed	A surface that has been enhanced by the addition of a loose material, other than that which occurs naturally at that location.
Mixed Trees	An area of cone-bearing trees (for example, yews, pines, firs, and larch) and trees that do not bear cones (for example, Ash, Aspen, Birch, Horse Chestnut, Maple, Oak, Poplar, and Sycamore), where the trees are generally spaced not more than 30m apart.
Non-Coniferous Trees	An area of trees that do not bear cones (including Ash, Aspen, Birch, Horse Chestnut, Maple, Oak, Poplar, and Sycamore), where the trees are generally spaced not more than 30m apart.
Rock	An aggregate of minerals that is part of the land mass and which covers 25 to 100% of an area.
Rough Grassland	Areas of bracken and uncultivated grassland, often tufted with a 'hummocky' appearance, and normally found on the higher parts of hills, mountains, and downland.
Sand	Minute particles resulting from the wearing down of rocks.
Scattered Coniferous Trees	An area of cone-bearing trees (for example, yews, pines, firs, and larch), where the trees are generally spaced more than 30m apart.
Scattered Mixed Trees	An area of cone-bearing trees (for example, yews, pines, firs, larch) and trees that do not bear cones (for example, Ash, Aspen, Birch, Horse Chestnut, Maple, Oak, Poplar, and Sycamore), where the trees are generally spaced more than 30m apart.
Scattered Non-Coniferous Trees	An area of trees that do not bear cones (these trees include Ash, Aspen, Birch, Horse Chestnut, Maple, Oak, Poplar, and Sycamore), where the trees are generally spaced more than 30m apart.
Scrub	All shrubs and bushes, including rhododendrons, brambles, gorse, and broom.
