The DFPRUNE spreadsheet program is designed to estimate the expected financial return from pruning coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii. It is a significant revision of the PRUNE-SIM program. The PRUNE-SIM program was based on the average product…

The PP PRUNE program allows users to conduct a financial analysis of pruning ponderosa pine (Pinus ponderosa Dougl. ex Laws.). The increase in product value and rate of return from pruning the butt 16.5-foot log can be estimated. Lumber recovery information is based on actual mill…

PRUNE-SIM is a spreadsheet template (program) that allows users to simulate a financial analysis of pruning coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii). The program estimates the increase in product value resulting from pruning the butt 17-foot log.…

Pruning of coast Douglas-fir was evaluated; recent product recovery information for pruned and unpruned logs for both sawn and peeled products was used. Dimensions of pruned and unpruned trees were simulated with the Douglas-fir stand simulator (DFSIM). Results are presented for a range of sites,…

Summarizes white pine blister rust research in the Lake States and present status of knowledge. Important microclimatic relations are described. Antibiotics are not effective, whereas pruning provides some control. Genetic resistance shows much promise but may be complicated by pathogenic races…

Diameters at age 10 of cottonwood (Populus deltoides Bartr. ex Marsh.) select clone Stoneville 66 planted at 40- by 40-foot spacing varied from 13.4 to 16.4 inches depending on height of pruning. Pruning treatments, applied from the 2nd through 8th years, were (1) unpruned, (2) pruned to a third…

This guide shows, in 110 photos, how discoloration and decay form in trees. An expanded concept of tree decay is given. After wounding, trees form boundaries to resist the spread of pathogens. The boundary-setting defense process is called compartmentalization, and model of the process is CODIT.…

In 1983, a study was conducted to evaluate the effects of leader topping and branch pruning on the efficiency to tree shaking to remove Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) cones. Removal efficiency for three topping and pruning treatments averaged 69 percent, whereas for the…

In recent years, eastern redcedar has been the most rapidly expanding tree resource in the Great Plains from Oklahoma to South Dakota, primarily in rangelands and pastures. Based on these increases and potential management-related problems, eastern redcedar is perceived as a threat to the rangeland…
