Thinning Ponderosa Pine In The Pacific Northwest

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.
