Reference State
Description
The reference state supports two community phases, which are grouped by the structure and dominance of the vegetation (e.g., graminoids, shrubs, and lichens) and by their ecological function and stability. The reference community phase is represented by tussock grassland consisting of hydrophilic graminoids, low and dwarf shrubs, and mosses. The presence of these community phases is dictated temporally and spatially by frost heave and collapse of frost heaved areas. No alternate states have been observed.
