This study represents an analysis of regeneration processes for eastern white pine (Pinus strohus L.). The objective is to develop an integrated approach to evaluate the influence of factors that, alone and in combination, determine regeneration outcomes. This study is composed of three sections. The first chapter is a literature review of white pine regeneration dynamics. The purpose is to present a process for understanding the regeneration process of a single species and present a conceptual approach to integrated evaluation of influential variables. Six interrelated ecological factors (seed tree density, competition, disturbance, seedbed conditions, soils, and damage agents) were identified and their impact on the regeneration process is evaluated. A conceptual model of the integration approach and two examples of how this approach can be utilized in assessing regeneration operations are presented.

Excerpt from Effect of Seedbed Condition on Regeneration of Virginia Pine After Logging The harvest removed all merchantable trees from the cut strips, and the remaining culls above 4 inches d.b.b. Were girdled and poisoned. Logs were skidded tree-length to roadside with a TD - 6 tractor and logging cart. It was esti mated that this operation exposed mineral soil on 15 to 30 percent of the area. In August 1953 the slash was broadcast burned; the fire consumed all of the light slash and, on about 60 percent of the area, at least some of the litter. Green brush and compact pine litter did not carry the fire. During the next 2 years, germination was tested on seedbeds created by the 1953 logging and slash-burning. The four strips were each divided lengthwise into three equal portions for separate sampling to determine whether shade or root competition from the uncut strip would influence germi nation and seedling survival. On each portion of each strip, three plots were established in November 1953, one each on undisturbed, disturbed, and burned seedbeds. This installa tion thus totaled 36 plots. In January 1955 a second set of 36 plots was established according to the same distribution, each plot being located within 25 feet of its 1953 counter part.

Wide variation in initial spatial patterns of natural regeneration of eastern white pine between managed & undisturbed white pine forests of the Great Lakes region has been attributed to differences in understory light levels and the frequency of substrates suitable for germination & seedling establishment. This paper describes a greenhouse study of the interaction of seed mass & light on early white pine which was undertaken to explore the potential influence of seed mass on these observed patterns. Seedlings of five families differing in mean seed mass were grown for 8 & 14 weeks under moderate & low light conditions representing managed & undisturbed pine stands respectively. The results suggest whether differential recruitment of white pine in managed & undisturbed stands is related to variation in seed mass.

S2The purpose of our study was to examine some of the factors that influence seedling emergence and seedling survival of direct-seeded white pine (Pinus strobus L.). Our major concern was the response of white pine to a particular set of growing conditions on the seedling emergence pattern, on seedling survival, and on the causes of seedling mortality. S3.
