Character Abstract
Identification Comments:Cones (or cone scales) are needed for positive identification.
Subspecies Comments:
Lookalikes:<i>Pinus flexilis</i> (limber pine) is almost indistinguishable from <i>Pinus albicaulis</i> in the absence of cones, and both species can form krumholz at its upper elevation limits.  While the absence of cones can be an indicator for <i>Pinus albicaulis</i>, it can also simply indicate non-reproductive (young or krumholzed) individuals of either species.  In reproductive individuals, there will usually be at least some disarticulated cone scale
Phenology Comments:
Reproduction Comments:
Habitat Comments:Thin rocky soils mostly on peaks, ridges, and exposed northerly aspects, usually in the subalpine zone, but descending on acidic altered andesite and other specialized soils well into the pinyon/juniper zone.
Ecology Comments:Important winter food source for multiple animal species.
