In the Aleutian Islands, wildflowers are king. Persistent low temperatures mean trees are unable to thrive, and so swaths of open tundra serve as the dramatic stage for a stunning variety of flowers. Wildflowers of Unalaska Island is the only guide to this flora, covering more than 160 species of flowering plants in a backpack-friendly book. Each species is introduced and clearly defined and is accompanied by a photograph and line drawings. Many of these plants occur across a wide range of coastal Alaska; others are unique to the Aleutians. The introduction includes background on the unique geologic history, climate, and habitats of the archipelago to fully round out the user’s appreciation of the dramatic environment in which these hardy plants thrive.
