Book excerpt: Excerpt from Crop-Tree Thinning of Ponderosa Pine in the Pacific Northwest Mowat has reported on several earlier crop-tree thinning studies made in the Pacific Northwest. Thinning treatments varied from ramov ing only trees with interlacing crowns to cutting all trees whose crowns were within 3 feet of the crop tree. Differences between growth of released and unreleased trees were small. Heavily released trees grew at the rate of only about 1 inch per decade compared to inch for selected crop trees in the unthinned stand. Furthermore, these early experiments did not show any clear-cut effect of overstory on understory tree growth and vice versa. The studies reported here go a step further as some crop trees were released to a point that approached area thinning. In addition, the interrelationships of overstory and understory tree growth were examined. Results are important to land managers who have trees already released by the crop - tree method and to managers who intend to embark on an extensive thinning program in ponderosa pine.

Book excerpt: Excerpt from Thinning Ponderosa Pine in the Pacific Northwest: A Summary of Present Information Protection during the past fifty years has prevented the destruo tion of these young trees by fire and they have developed into seedling, sapling, or pole stands. Occurrence, size and density of these young stands vary widely, depending on the site and particular history of each spot and on the amount of overwood. 'where the mature stand was very dense, few pine seedlings have survived, But where the stand was more open as a result of fires, bark beetles or other causes, reproduction has often grown into dense patches of saplings or poles. In many places the young growth has now been fully released by logging of the overstory trees; elsewhere it is still held back by the remaining overstory.

Book excerpt: Excerpt from Large-Crowned Planted Ponderosa Pine Respond Well to Thinning Thinning study results provide a portion of the information on which timber stand improvement policy is formulated. To be useful these studies should sample a wide range of sites, tree sizes, age classes, and geo graphic locations in planted and natural stands. The study reported here is one of a number of thinning experiments established in various stands through out the Pacific Northwest during the period from 1957 to 1965. This report summarizes initial 11 - year results after thinning a 33 - year - old ponderosa pine plantation. 1.
