Excerpt from Natural Regeneration in Ponderosa Pine Forests of Western Montana Following harvest cutting, natural regeneration of ponderosa pine (pinus ponderosa Laws.) in western Montana usually is uncertain. Therefore, forest managers frequently rely on planting to promptly regenerate ponderosa pine and prevent future gaps in volume production. When the forester decides to restock an area by natural regeneration, he must effectively manipulate the factors under his control that influence seedling establishment. Good ponderosa pine seed crops occur at irregular intervals (usda Forest Service thus, timing of site preparation to coincide with seed production is a critical requirement for successful natural regeneration. Once cones are initiated, it is important to understand the factors influencing their survival. In addition, stimula tion of cone production by girdling or release of seed trees would be a useful tool if ponderosa pine responds to either of these treatments. Even when a sufficient seed crop is produced, the success of natural regeneration is further influenced by: (l) dissemination to a favorable seedbed; (2) seed loss to biotic agents; (3) germination of the remaining seed; and (4) survival of germinated seedlings.
