The European aspen Populus tremula and the closely related Quaking aspen Populus tremuloides of North America have the widest natural range of any tree species in the world. Aspen was one of the first tree species to colonise the landscape after the last ice age. Its ability to produce large numbers of suckers has resulted in extensive stands of single aspen clones covering many hectares, which some regard as being the largest, and oldest, living organisms on the planet. Aspen is a keystone species for a diversity of flora and fauna throughout its range. It plays a valuable role in landscape diversity and amenity. In North America and the Baltic States, aspen is an important timber tree. The purpose of this review is to collate information from published sources and provide an up-to-date account of current knowledge relating to aspen, with particular reference to Scotland.
