| Additional Notes | The native woodland at How Edge Scars is perhaps the best example of native woodland once widespread across the open moorland of Upper Swaledale.
The seperate populations of aspens located on the eastern slopes at the lower and upper parts of the ravine and on the north facing cliff at the top of the ravine on the westside of the stream are of special interest as are the scattered junipers and above all the uniquely interesting overhanging tufa formation on the cliff at the top of the ravine colonised by non-flowering plants, mosses, lichen, algae and diatoms.
Colonies of stone bramble,oak and beech fern also present.
Upper (MUK121) and Lower Parts (MUK120) of the ravine recorded seperately to allow seperate presentation of the isolated junipers and aspen groves. |
