Historically, large areas of pasture in Wales have been intensively grazed by sheep, leaving most of the upland grasslands in Wales extremely poor in terms of biodiversity interest: it isn’t uncommon to come across signs of intensive sheep-grazing (as shown in the image above). In the lowlands, in addition to the intensive-grazed sheep pastures, many of the cattle-grazed pastures have been reseeded with high productivity, grass-dominated seed-mixes, these typically ‘bright green’ pastures are also poor in terms of associated biodiversity interest.
