DescriptionThe effects of competing herbaceous vegetation on the growth of ponderosa pine seedlings with and without herbicide Pronone were characterized in this 1987-1990 study. Study areas were established in 36 plantations across western Montana on Champion International Corporation's timberland (currently owned by Plum Creek Timber Company). The study sites were divided into three precipitation classes; low, medium, and high. Mean percent stem volume growth was calculated for 3 years by precipitation class. Split-plot analyses of variance for precipitation class, treatment, and interaction were conducted across sites between treated and untreated seedlings to test for significant (a=0.05) differences in growth. A two-dimensional plot of precipitation class by treated seedlings showed significantly higher stem volume growth than their untreated counterparts regardless of precipitation class. The difference between treated and untreated seedlings was statistically significant.
