One striking feature of Shetland's landscape that any visitor will invariably notice is the trees, or rather the lack of them. The islands are devoid of any large trees for the most part. It is due to its harsh weather conditions - cold, corrosive with gales 120 mph on a "normal" wintery day. So a splash of green canopy is almost a luxury here. Kergord near Whiteness, at the bottom of a glacial valley is Shetland's only forest, guarded from wind by mountains carved by ice millenia back.
