Britain's uplands were once all covered in mainly broadleaf oak woodland.
Along came Neolithic man (during the late 'stone' age) and cleared vast tracts
for his grazing animals and in some areas for the planting of crops. The animals and
the human population increased and in most places the trees never managed to
return.
However during the twentieth century the need for timber resulted
in the planting of vast blocks of non native conifer. Before this
afforestation, the mountains and moorlands had developed rich and fascinating
communities of plants and animals, under the influence of sheep grazing and
latterly management of heather for red grouse shooting.

As our uplands are largely on hard acidic rocks such as granite, and are
found in places where it rains an awful lot, the soils become acidic, nutrient
poor and often saturated with water. Along with the factor of
altitude, only certain plants can cope with these conditions and hence the
community that is found in such situations is quite distinctive.
The trees species include scattered Scots pines (in the Scottish
highlands), downy silver birch and juniper. The understory is
dominated by heather (ling, bell heather and cross-leaved
heath) which provides a purple patchwork when seen in flower in late
summer and early autumn. The dominant grass is purple moor grass
along with fescue species and matt grass where the ground is
higher. In wetter and harder grazed areas rushes can dominate.
Where water is a permanent feature sphagnum moss is an important
element of the vegetative cover and can form vast impenetrable bogs.
In these conditions exciting plants such as the insect consuming
butterwort and sundew can be found and the yellow flowered bog
asphodel can also be frequent.
