    Description

    Southwestern white pine (Pinus strobiformis, SWWP) is a component of dry and wet mixed-conifer forests in the southwestern United States and provides ecological function and diversity. The species is geographically limited to Arizona, New Mexico, parts of Texas, southern Colorado, and northern Mexico, but occurs on a wide range of habitats within its distribution. Historically, SWWP regeneration has not been well studied or monitored in mixed-conifer forests of the Southwest, although our understanding of the species’ ecology is increasing. Introductions of Cronartium ribicola, the pathogen responsible for causing white pine blister rust (WPBR), are fairly recent compared to other areas in North America, and disease intensity is variable in the Southwest. Heavy disease occurs in south-central New Mexico, whereas many forests in Arizona are not affected yet. However, the disease continues to spread west through isolated mountain ranges in the Southwest.
