Ponderosa pines are the most important timber producing species in Mexico, and they also represent a major portion of the Usa and Canada timber production. These pines form near pure stands with simple and stable stand structure.
Ponderosa pine stands have been managed to provide a wide range of outputs and values by using these silvicultural systems, including timber, habitat for large game and avian species, protection of wildland resources from damaging insects, disease, or wildfire, quality forage for domestic ungulates, and water.
Ponderosa pine forests (trees with crowns overlapping, forming 60-100% cover) are mainly found on north- and east-facing slopes and bottoms. Ponderosa pine woodlands (open stands of trees, generally forming 25-60% cover) and mixed-grass prairie often occupy the south- and west-facing slopes.
ponderosa pine forests can often withstand ground-level fires, droughts, and other threats with low mortality. Heights of these stands depend on age and local climate conditions; drier locations
Ponderosa pine is a large tree that lives 300 to 600 years and reaches heights of 30 to 50 m tall and 0.6 to 1.3 m in diameter. The oldest trees can exceed 70 m in height and 2 m in diameter.
Abstract. Ponderosa pine is a wide-ranging conifer occurring throughout the United States, southern Canada, and northern Mexico. Since the 1800s, ponderosa pine forests have fueled the economies of the West. In western North America, ponderosa pine grows predominantly in the moist and dry forests.
Description. Pinus ponderosa P. & C. Lawson, is a large, long-lived, native forest tree common throughout the western U.S. Height of mature trees range from 55 to 90 feet. Diameter breast high ranges from 15 to 35 inches. Age at maturity ranges from 70 to 250 years.
