FEIS ABBREVIATION:
PINLON

SYNONYMS:
Pinus aristata Engelm. var. longaeva D.K. Bailey [63]

NRCS PLANT CODE [132]:
PILO

COMMON NAMES:
Great Basin bristlecone pine
intermountain bristlecone pine
western bristlecone pine

TAXONOMY:
The scientific name of Great Basin bristlecone pine is Pinus longaeva D.K. Bailey (Pinaceae) [9,44,62,136].

Great Basin bristlecone pine, Rocky Mountain bristlecone pine (P. aristata), and foxtail pine (P. balfouriana) share a common ancestor [111,142]. Taxa within the bristlecone-foxtail pine complex (Pinus, subgenus Strobus, section Parrya Mayr, subsection Balfourianae Englm.) are distinguished by growth form, bark, and differences in chemical composition [9,30,98,105]. Bristlecone and foxtail pines readily produce fertile hybrids in the laboratory [122,142]. Disjunct distributions, and possibly other factors, prevent natural hybridization among the 3 species. Great Basin bristlecone and southern foxtail pine (P. b. ssp. austrina) populations seem geographically close enough for limited pollen dispersal (see General Distribution); yet to date (2004), Great Basin bristlecone  southern foxtail pine hybrids have not been found in the field [9,86].

LIFE FORM:
Tree

FEDERAL LEGAL STATUS:
No special status

OTHER STATUS:
The California Native Plant Society (CNPS) places Great Basin bristlecone pine on their watch list (CNPS List 4) as a plant of limited distribution in California [113]. The World Conservation Union's Species Survival Commission (IUCB-SSC) lists Great Basin bristlecone pine as vulnerable, with this classification needing updating [60].
