Further up the hill Scot’s pine gives way to juniper, whilst dramatic, inaccessible corries and crags guard some of the few relics of mountain willow populations remaining in Britain. These include the rare downy willow (Salix laponum), woolly willow (Salix lanata), whortle leaved willow (Salix myrsinites) and the net leaved willow (Salix reticulata).

Away from the rock faces on exposed high altitude plateaux dwarf birch (Betula nana) can be found amongst the expanses of blanket bog. This is another rare dwarf tree which, along with mountain willows, juniper, stunted pine and birch would have formed a patchy, low canopy of montane woodland above the tall pine forests before giving way to open mountain tops.
