Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Goodding''s Willow / Narrowleaf Willow Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian woodland is known primarily from the Colorado Plateau and is characterized by tall Salix gooddingii trees with a tall-shrub understory dominated by Salix exigua. Other woody species present may include Forestiera pubescens, Celtis laevigata var. reticulata, and non-native Tamarix spp. The herbaceous undergrowth includes graminoid species such as Eleocharis rostellata, Equisetum laevigatum, Juncus arcticus, and Schoenoplectus pungens, and native forbs such as Ambrosia acanthicarpa, Salsola tragus, and Xanthium strumarium. Sites are gently sloping alluvial terraces, sandy wash bottoms, canyon bottom drainage channels or streams, and narrow slickrock canyons where the water table generally remains within the rooting zone of the trees throughout the growing season, and are known to occur from 1098 to 1835 m in elevation.

Floristics: This riparian woodland is characterized by an open to moderately dense tree canopy (up to 85% cover) that is dominated by 10- to 35-m tall Salix gooddingii trees. Scattered Celtis laevigata var. reticulata (= Celtis reticulata) and emergent Populus fremontii or Populus angustifolia trees may be present in or above the tree canopy. The tall-shrub understory is dominated by Salix exigua, usually with 35 to 45% cover. Other shrubs present include Ericameria nauseosa, Atriplex canescens, Ephedra viridis, and Forestiera pubescens, the vine Parthenocissus vitacea, and non-native Tamarix chinensis. Native graminoid species may include obligate and facultative wetland species such as Eleocharis rostellata, Equisetum laevigatum, Juncus arcticus, Schoenoplectus pungens, and Typha sp. The herbaceous layer often consists largely of forbs such as Ambrosia acanthicarpa, Artemisia ludoviciana, Eurybia glauca (= Aster glaucodes), Salsola tragus, and Xanthium strumarium, or the introduced pasture grass Schedonorus arundinaceus (= Festuca arundinacea) and the invasive annual Bromus tectorum. Seedling Populus fremontii may also be present in the ground layer.
Dynamics: Salix exigua is often associated with sand bars and scoured banks that are characteristic of streams with active flooding.
Environmental Description: This riparian woodland occurs on sandy wash bottoms, alluvial terraces, and in narrow slickrock canyons of the Colorado River, Lake Powell, and their tributaries. Water tables remain within the rooting zone of the trees throughout the growing season. Sites are gently sloping and occur at 1099-1835 m elevation. The ground surface has high litter cover with some sand, bare soil, or large rocks. Soils are intermittently moist to saturated loamy sands to poorly drained sandy clay derived from alluvium.
Geographic Range: This association is known primarily from the Colorado Plateau, documented from Arches and Canyonlands national parks and Glen Canyon National Recreation Area, as well as from isolated locations in eastern New Mexico.
