MAPPING UNIT NAME: Meadow tundra type.

DOMINANT SPECIES: Dominance various

DESCRIPTION: This type includes graminoid and forb dominated vegetation
that occurs above upper treeline in the alpine zone. Common species include
various sedges (Carex sp.), low growing willows (Salix sp.), grasses and
forbs.

DISTRIBUTION: Above timberline throughout the state of Colorado.

ELEVATION RANGE: Above timberline

DIAGNOSTIC SPECIES: Carex sp., Salix sp.

NOTES: Alpine ecosystems occupy those mountain areas above timberline
that are characterized by short, cool growing seasons and long, cold
winters. The vegetation is characteristically dominated by low growing (20
cm. or less) perennial, herbaceous and shrubby vascular plants, extensive
mats of cryptograms (mosses, lichens, etc.) and the almost complete
absence of trees. Topographic site, degree and duration of winter snow
cover and exposure to the wind are major influences (Thilenius, 1975).
