This study investigated the changes in the spatial distribution of lodgepole pine stands as regeneration proceeds. Data were collected from 29 plots established in regenerating lodgepole pine stands and remeasured two years later. Nine of these plots had sufficient ingrowth to warrant an analysis of their spatial distribution dynamics. Ripley's K(t) statistic was used to identify the spatial pattern of the trees at the initial measurement, the ingrowth trees, and the combined initial and ingrowth trees. The K(t) statistic was also employed to detect correlation between the locations of the initial and the ingrowth trees. The spatial patterns were modelled by a Poisson cluster process, a Poisson process, or a Markov point process when the trees were aggregated, random, or regularly distributed, respectively.

A sequence of events is necessary for natural regeneration in the pumice soil region: Adequate seed must be probed and distributed over the area, germination must be favored by warm and moist surface soils, daily surface temperature variation must be moderate, seedlings must survive summer drought, and weather conditions must prevent severe frost heaving the fall after germination and the next spring. This sequence does not always occur within a reasonable time after cutting, and natural regeneration is often delayed. Four possibilities are open to the land manager: (1) declare as noncommercial some severe sites such as lodgepole pine/needlegrass and lodgepole pine/bitterbrush/needlegrass plant communities on flat or basin topography; (2) depend more on a planting program; (3) leave a light slash cover on the surface after shelterwood or narrow strip cutting; and (4) leave a shelterwood on the area after a more thorough slash treatment and be willing to wait much longer than 5 years for natural regeneration. Some problems now exist in obtaining good lodgepole planting stock. Also the slash cover does not guarantee success of natural regeneration and option 3 might turn into option 4.

Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.
