Growing Regions

Southwestern white pine has a limited distribution. It is found in the mountains of western Texas, New Mexico, Arizona, and southwestern Colorado [15,16,50]. It extends south along the mountains to central Mexico; most of its distribution is in Mexico [44,50,65].

     

General Information

The currently accepted scientific name of southwestern white pine is Pinus strobiformis Engelm. [6]. There are no recognized subspecies, varieties, or forms. Southwestern white pine hybridizes with limber pine (P. flexilis James) where their ranges overlap [6,17,53].

Southwestern white pine normally occurs in low densities in southwestern
pine, mixed-conifer, and spruce-fir forests [67].  It occurs as an
associate in habitat type series of the major conifers in these forests
[3,4,5,17,26,52].  Southwestern white pine infrequently forms small pure
stands; it is most likely to be dominant in high-elevation, cool
habitats [49,51,53].

Southwestern white pine may be present as a minor component in riparian
community types in south-central Arizona and in the montane riparian
woodland zone of southwestern Colorado [9,70].

Southwestern white pine is listed as an indicator species in the
following publications:

(1)  Classification of the forest vegetation on the National Forests of
       Arizona and New Mexico [5]
(2)  A classification of forest habitat types of northern New Mexico and
       southern Colorado [18]
(3)  Forest habitat types in the Apache, Gila, and part of the Cibola
       National Forests, Arizona and New Mexico [26]
(4)  Forest and woodland habitat types (plant associations) of northern
       New Mexico and northern Arizona [49]
(5)  A classification of spruce-fir and mixed conifer habitat types of
       Arizona and New Mexico [51].
