CEGL001118 Quercus x pauciloba / Cercocarpus montanus Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Wavyleaf Oak / Alderleaf Mountain-mahogany Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association occurs in the mountains of north-central and south-central New Mexico. It occurs predominantly on steep and rocky canyon sideslopes (40-70% slope), but occasionally on rockier sites of rolling plateau mesas. Elevation ranges between 2050 and 2280 m (6740-7500 feet). Soils are poorly developed and rocky Entisols derived from rhyolitic tuff parent materials, or simply rock outcrop. The ground surface is characterized by scattered bunchgrasses and litter amid rocks and boulders. The vegetation within these montane shrublands is dominated by the hybrid scrub oak Quercus x pauciloba and Cercocarpus montanus, which can form thickets with 50% or more canopy cover. Fallugia paradoxa and Robinia neomexicana are also common shrub associates. Among trees, scattered Juniperus monosperma and Pinus ponderosa saplings and mature trees may occur, but cover is less than 10%. The herbaceous layer is variable in composition and seldom exceeds 10% total cover.

Floristics: Within Bandelier National Monument in north-central New Mexico, these montane shrublands are dominated by the hybrid scrub oak Quercus x pauciloba and Cercocarpus montanus, which can form thickets with 50% or more canopy cover. Fallugia paradoxa and Robinia neomexicana are also common shrub associates. Among trees, scattered Juniperus monosperma and Pinus ponderosa saplings and mature trees can occur, but cover is less than 10%. The herbaceous layer is variable in composition and seldom exceeds 10% total cover. Scattered grasses are predominant and may include Bouteloua curtipendula, Bouteloua gracilis, Muhlenbergia montana, and Schizachyrium scoparium. The most prevalent forbs are Artemisia ludoviciana, Eriogonum jamesii, and Heterotheca villosa. Within White Sands Missile Range in south-central New Mexico, this association is a minor and provisional type, is very chaparral-like, and is codominated by Cercocarpus montanus and Quercus x pauciloba. Other shrub associates usually present include Garrya flavescens, Mahonia haematocarpa, Nolina microcarpa, and Rhus trilobata. Grasses and forbs are usually poorly represented.

Environmental Description: Within Bandelier National Monument in north-central New Mexico, this mid-elevation association occurs between 2050 and 2190 m (6740-7200 feet) on sites with moderate solar exposure. Stands are mostly found on steep and rocky canyon sideslopes (40-70% slope), but occasionally on rockier sites of rolling plateau mesas. Soils are mapped as poorly developed and rocky Entisols derived from rhyolitic tuff parent materials, or simply as rock outcrop (Hibner 2009). The ground surface is characterized by scattered bunch grasses and litter amid rocks and boulders. Within White Sands Missile Range in south-central New Mexico, this association occurs on steep, warm scarp slopes at elevations ranging from 2130 to 2280 m (7000-7500 feet).
Geographic Range: This shrubland association occurs in the mountains of north-central and south-central New Mexico.
