This includes both non-native broadleaved habitat and conifer habitat. The value of the habitat for forage depends on the species of tree and the tree density.
Once they have closed canopy, conifers such as Sitka spruce and western hemlock will suppress the field layer to the point where very little can survive and the forage availability is zero.
Deciduous conifers such as larch and widely-spaced conifers may have a field layer comparable to broadleaved woodland growing in a similar environment.
Mature beech woodland may suppress the field layer as effectively as close-grown conifers, resulting in very little or no forage availability. Other broadleaves, such as sycamore, will support a field layer comparable to native woodland growing at similar densities.
Policy woodland and groups of mature broadleaved trees in native woodland may have conservation value because the presence of large, mature trees provides habitat to lower plants and small animals. In areas where red squirrels occur, stands of Scots pine, larch and Norway spruce may provide valuable squirrel habitat.
