Imperiled globally - The subspecies/variety is at high risk of extinction due to rarity or other factors; typically 20 or fewer populations or locations in the world, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. (The species as a whole is apparently secure globally.)
