    Ponderosa Pine Pinus ponderosa. The Ponderosa pine is a large, straight trunked tree with a wide, open, irregularly cylindrical crown. The narrow to broad pyramidal crown on young trees flattens out on old trees with lower branch loss. The bark on the young trees is blackish or dark red-brown and furrowed, and on mature trees yellow brown to. was published posthumously in Ponderosa is from the Latin ponderosus,meaning large, heavy, or weighty. Douglas’s collection introduced the species to British horticulture; of the three recognized varieties, two of them, var. ponderosa (Pacific ponderosa pine) and var. scopulorum (Rocky Mountain ponderosa pine), are found in Oregon.

Ponderosa pine (Pinus ponderosa) is a North American pine discovered in by David Douglas near Spokane, Washington. A few common names for the species include yellow pine, western pine, and Sierra redbark among many others. Pinus ponderosa belongs to the Plantae kingdom, Pinophyta division, Pinopsida class, Pinales order, and Pinaceae family.

    Net photosynthetic rate (A), stomatal conductance (B), and basal area increment (C) from a study of old ponderosa pine in central Oregon (McDowell et al., ) shows that thinning stimulated leaf gas exchange and radial growth 1 year after thinning, and increases growth 4 years after thinning. The shelterwood stand was thinned in , and the Cited by: California Montane Jeffrey Pine/(Ponderosa Pine) Woodland. This ecologi-cal system is found on relatively dry sites in mountains and plateaus in southern Oregon from m (1,, ft) in elevation. Stands are pure Jeffrey pine, ponderosa pine, or a .

dense stocking of ponderosa pine does reduce height growth. Reducing the density below levels found in natural stands usually affects the height growth patterns shown by Meyer () for "normal" stands. Fortunately, there seems to be a rather broad density range in ponderosa pine stands where density does not affect height growth of the larger.
