Changes in Ponderosa Pine Site Productivity following Removal of Understory Vegetation
Competition from understory vegetation for water and nutrients can limit productivity of young forest stands. Less is known of the effect of understory vegetation on long-term stand growth or soil organic properties. The effect of understory vegetation on periodic annual increments (PAIs) of basal area, height, and volume for ponderosa pine (Pinus ponderosa Doug].) in central Oregon at 4 or 5-y...
متن کاملResource Limitations Influence Growth and Vigor of Idaho Fescue, a Common Understory Species in Pacific Northwest Ponderosa Pine Forests
Alterations in under-canopy resource availability associated with elevated ponderosa pine (Pinus ponderosa Dougl.) abundance can negatively influence understory vegetation. Experimental evidence linking under-canopy resource availability and understory vegetation is scarce. Yet this information would be beneficial in developing management strategies to recover desired understory species. We tes...
متن کاملPonderosa Pine Seedlings and Competing Vegetation: Ecology, Growth, and Cost
Foresten oftm need information on the cost effedivenessofmanual and chemical release treatments for individual and combined species in young mixed-shrub communities. A studvin northern Califomia evaluated fivemanual and chemical treatmcnts and their effect an several shmbs and grasses. Treatments were grubbing at age 1 to 2-and 441 (0.6-and 1.2-m) radii, regrubbing and expanding the 2-ft radii ...
متن کاملUnderstory vegetation, resource availability, and litterfall responses to pine thinning and woody vegetation control in longleaf pine plantations
In s ix 8to 1 1-year-old plantat ions of longleaf pine (Pinus palus tr i s Mill.) near Aiken, S.C., responses of understory vegetation, light, and soil watcr availability and litterfall were studied in relation to pine thinning (May 1994), herbicida1 treatment of nonpine woody vegetat ion (1995-1996), or the combined treatments (treatment responses described below are in absolute units) . Treat...
متن کاملStand structure in eastside old-growth ponderosa pine forests of Oregon and northern California
Quantitative metrics of horizontal and vertical structural attributes in eastside old-growth ponderosa pine (Pinus ponderosa P. and C. Lawson var. ponderosa) forests were measured to guide the design of restoration prescriptions. The age, size structure, and the spatial patterns were investigated in old-growth ponderosa pine forests at three protected study areas east of the crest of the Cascad...
