CEGL000886 Abies concolor / Leymus triticoides Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: White Fir / Beardless Wildrye Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association is restricted to upper elevations between 2750-3020 m (9000-9900 feet) in the Capitan Mountains of south-central New Mexico. It occurs on steep slopes with cobbly soils derived from talus. Abies concolor is the dominant in association with Pseudotsuga menziesii and Pinus strobiformis. Picea engelmannii and Abies lasiocarpa are absent or accidental. Shrubs are well-represented (Holodiscus dumosus, Acer glabrum, and Quercus gambelii), but the grass Leymus triticoides is abundant to luxuriant, and diagnostic in the herb layer.
Diagnostic Characteristics: Abies concolor and Pseudotsuga menziesii are dominant. Picea engelmannii and Abies lasiocarpa regeneration are absent; other timber species are rare. Pinus strobiformis is not important or may be absent. A light density tall-shrub layer is present. The herbaceous layer is dominated by grasses such as Leymus triticoides and Bromus ciliatus. Forb representation is minimal. Soils are rubble pavements or extremely cobbly; grass cover being interrupted by patches of surface cobble.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This type is similar to other scree/talus types such as ~Picea engelmannii / Leymus triticoides Forest (CEGL000362)$$, ~Abies lasiocarpa / Holodiscus dumosus Scree Woodland (CEGL000918)$$, and ~Abies lasiocarpa / Jamesia americana Forest (CEGL000312)$$.

Floristics: Abies concolor is the dominant in association with Pseudotsuga menziesii and Pinus strobiformis. Picea engelmannii and Abies lasiocarpa are absent or accidental. Shrubs are well-represented (Holodiscus dumosus, Acer glabrum, and Quercus gambelii), but the grass Leymus triticoides is abundant to luxuriant, and diagnostic in the herb layer.
Dynamics: Presence of aspen in a minor seral role indicates that low intensity fires have been a part of the ecology of those stands.
