| 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. |
| Inventory Comments: | |
| Inventory Needs: | |
