(1) Pasture (also grassland or paddock) is used in contrast to meadow for primarily grazing, which may include grassland (“grass pasture”), but also includes nongrassland habitats such as heathland, moorland and wood pasture. Pasture growth can consist of grasses, legumes, other forbs, shrubs or a mixture.
