Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Engelmann Spruce / Ross'' Avens Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association is characterized by nearly pure stands of Picea engelmannii. Where present, the herbaceous cover is dominated by Geum rossii. Abies lasiocarpa may be an accidental species. Shrubs are sparse. Other common herbs include Aquilegia chrysantha, Festuca brachyphylla ssp. brachyphylla, Mertensia franciscana, Moneses uniflora, Polemonium pulcherrimum ssp. delicatum, and Trisetum spicatum. This type occurs on north-facing high mountain slopes where moist soils often remain snow-covered until June. Elevations range from 3150 to 3420 m (10,500 feet) to timberline. It is known from San Francisco Peaks, near Flagstaff, Arizona.
Diagnostic Characteristics: Characterized by nearly pure stands of Picea engelmannii. Where present, the herbaceous cover is dominated by Geum rossii. Abies lasiocarpa may be an accidental species.
