Wind Egg supports just isolated trees of Rowan and Hawthorn. Lower down Willys Gill and in comparative shelter, the Middle and Lower Scars (see SWAAG Records to follow this)support a more varied limestone ashwood community with mature ash trees, a small cloned colony of about 12 aspens, a few downy birch, wych elms (all visibly dead, but probably springing from the roots, rowans, sallows, shrub willows, much vigorous bird cherry, rowan, hazel, hawthorn and blackthorn and downy rose. Recorded and photographed from the opposite bank of Willy's Gill Beck. Notably absent are yews and juniper which would probably be present at similar elevation and localities in Swaledale. |
