Curlleaf mountain-mahogany usually occurs in isolated, pure patches that are often very dense. In the Great Basin, curlleaf mountain-mahogany may form a distinct belt on mountain slopes and ridgetops above pinyon-juniper woodland [9,33,52]. In the Rocky Mountain Region, curlleaf mountain-mahogany is associated with skunkbush sumac (Rhus trilobata), antelope bitterbrush (Purshia tridentata), serviceberry (Amelanchier spp.), and western juniper (Juniperus occidentalis) [14]. As a codominant member of the sagebrush-forest ecotone in Idaho, curlleaf mountain mahogany is associated with snowberry (Symphoricarpos spp.), mountain big sagebrush (Artemisia tridentata ssp. vaseyana), green rabbitbrush (Chrysothamnus viscidiflorus), bluebunch wheatgrass (Pseudoroegneria spicata), Sandberg bluegrass (Poa secunda), Idaho fescue (Festuca idahoensis), and Columbia needlegrass (Stipa columbiana) [47]. Curlleaf mountain-mahogany occurs in mid-elevation forests that do not develop dense canopies. It is commonly associated with limber pine (Pinus flexilis), lodgepole pine (P. contorta), ponderosa pine (P. ponderosa), Douglas-fir (Pseudotsuga menziesii), Englemann spruce (Picea engelmannii), subalpine fir (Abies lasiocarpa), and white fir (A. concolor) [4,5,10,33]; it may also occur with quaking aspen (Populus tremuloides) and whitebark pine (Pinus albicaulus) above 9,000 feet in the Great Basin [33]. In Utah curlleaf mountain-mahogany is associated with maple (Acer spp.)-oak (Quercus spp.) woodlands [5]. Publications listing curlleaf mountain-mahogany as a dominant or codominant species include: Habitat characteristics of the Silver Lake mule deer range [11] Sagebrush-grass habitat types of southern Idaho [22] Preliminary descriptions of the terrestrial natural communities of California [23] Plant associations of the Fremont National Forest [24] Plant associations of the Wallowa-Snake Province: Wallowa-Whitman National Forest [28] Flora and major plant communities of the Ruby-East Humboldt Mountains with special emphasis on Lamoille Canyon [36] Grassland and shrubland habitat types of western Montana [41] Forest habitat types of the South Warner Mountains, Modoc County, California [46] Forest habitat types of central Idaho [53] Coniferous forest habitat types of central and southern Utah [63]
