Some plants bloom only in special, very limited habitats; others tolerate a variety of growing conditions. The following thirteen categories describe the habitats of Colorado:
Tundra: Land above tree line characterized by a short growing season, intense sun and wind, thin soils, very high snow fall and high rain fall, and low growing sedges, grasses, dwarf shrubs, and herbs.
Scree: Fields (often extensive) of small, loose, slab rock. Common below tree line and very common above tree line. Pockets of endemicwildflowers where soils accumulate.
Woodlands: Areas forested with Spruce, Fir, Pine, Aspen, Oak, Juniper, Douglas Fir.
Wetlands: Wet meadows, fens, seeps, etc.
Streamsides: Moist areas along streams.
Openings: Small to large clearings in various vegetation zones. The openings are caused by soil conditions, fire, wild animals, or man .
Meadows: Grass, shrub, and wildflower-filled large open areas with few, if any, trees.
Rocks: Areas of large rock in canyons or mountains.
Canyons: Deep and long depressions with walls of cliffs and slopes. Pinyon Pine, Juniper, and Sagebrush are common.
Shrublands/Grasslands: Arid lands characterized by shrubs, grasses, and a lack of trees.
Prairies: Low elevation, gently rising and falling lands of grasses, wildflowers, and few trees.
Disturbed areas: Roadsides, mined areas, timbered lands.
Semi-deserts: Shrublands, grasslands, Pinyon-Juniper woodlands, or sand and gravel relatively barren lands.
