DISTRIBUTION AND OCCURRENCE
GENERAL DISTRIBUTION:Alligator juniper occurs from western Texas to northwestern New Mexico and reaches its northern limit in north-central Arizona near Flagstaff. It extends southward into northern and central Mexico where it is described as "widespread" [37,79,80,82,84,125]. Distribution of varieties is as follows [138]:
ECOSYSTEMS:FRES21 Ponderosa pine FRES28 Western hardwoods FRES29 Sagebrush FRES32 Texas savanna FRES34 Chaparral-mountain shrub FRES35 Pinyon-juniper FRES36 Mountain grasslands FRES37 Mountain meadows
STATES:AZ CO NM TX MEXICO
BLM PHYSIOGRAPHIC REGIONS:7 Lower Basin and Range 12 Colorado Plateau 13 Rocky Mountain Piedmont

HABITAT TYPES AND PLANT COMMUNITIES:Alligator juniper occurs in pinyon-juniper (Pinus-Juniperus spp.), pine-oak (Pinus-Quercus spp.), juniper-oak, Madrean evergreen, and riparian woodlands, and in ponderosa pine (P. ponderosa) forest. It rarely grows in dense stands. Typically, it occurs in small groves or as individuals interspersed with other junipers, ponderosa pine, oaks, or various understory species [6,86,103]. Alligator juniper is a common component of pinyon-juniper woodlands with pinyon (P. edulis) and/or singleleaf pinyon (P. monophylla). It occurs at somewhat higher elevations than oneseed or Utah juniper [26,72,86]. Pinyon-juniper woodlands make up more than one half of New Mexico's forested lands, and alligator juniper represents approximately 7% of all trees within that area [24]. Alligator juniper also occurs in pine-oak woodlands of Arizona. Along with Mexican pinyon (P. cembroides) [31], it is an important constituent of juniper-oak woodlands of the Colorado Plateau [139]. In parts of southern Arizona and Mexico, it occurs in Madrean evergreen woodlands with various oaks and pines and in lower elevation, pygmy conifer-oak woodlands [10,84,122,126,]. These woodlands are characterized by having less oneseed juniper, Rocky Mountain juniper, and pinyon, but greater amounts of alligator juniper, Emory oak (Q. emoryi), gray oak (Q. grisea), Arizona white oak (Q. arizonica), and Mexican pinyon [20]. Tree species commonly codominating with alligator juniper include pinyon, oneseed juniper, ponderosa pine, and gray oak. Common shrub associates include skunkbush sumac (Rhus trilobata), true mountain-mahogany (Cercocarpus montanus), desert ceanothus (Ceanothus greggii), pointleaf manzanita (Arctostaphylos pungens), Apache plume (Fallugia paradoxa), and Parry agave (Agave parryi). Blue grama (Bouteloua gracilis), sideoats grama (B. curtipendula), vine-mesquite (Panicum obtusum), wolftail (Lycurus phleoides), bottlebrush squirreltail (Elymus elymoides), mountain muhly (Muhlenbergia montana), pine muhly (M. dubia), and bullgrass (M. emersleyi) are frequent grass associates of alligator juniper [11,73,96,109]. Alligator juniper is named as a dominant or indicator species in several pinyon-juniper and montane forest vegetation classifications.
