This book was released on 1996 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a study that identified and modelled the spatial pattern of trees in lodgepole pine sites in two biogeoclimatic variants in British Columbia. The K(t) statistic was used to detect the patterns and provide a basis for determining an appropriate spatial process model. Most sites had an aggregated pattern which was modelled effectively by a Poisson cluster process. An equation describing the relationship between the parameters of the Poisson cluster process model was developed. Random patterns occurring in the plots were modelled by a Poisson process and regular patterns by a Markov point process and a lattice-based process. The appendix contains the algorithm for the processes used.

This book was released on 1997 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2016 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1988, three studies were established as part of Experimental Project 995 to study lodgepole pine (Pinus contorta var. latifolia) survival and growth responses to site preparation in the Sub-Boreal Spruce zone of north-central British Columbia. The project examines the effectiveness of several mechanical treatments and localized high-intensity burning, with a focus on disc trenching, which is the most commonly used mechanical site preparation technique in this region. The importance of disc trench orientation, planting aspect, and planting position were investigated, as well as potential interactions between broadcast burning and disc trenching. This report presents 25-year results for the Bednesti North and Bednesti South experiments, and 19-year results for the Tanli experiment. Treatment effects are discussed in relation to: lodgepole pine establishment (survival and early growth to age 5); performance at approximately free-growing age (9 years); and early mid-term growth, stand volume, and site index (as measured at age 25). Of the mechanical treatments tested, coarse mixing was the most effective, resulting in approximately 1-m gains in lodgepole pine height over the control at age 25. This treatment is not practical from an operational perspective, however, and the more common technique of disc trenching with trees planted at the hinge produced the second greatest gains. In contrast, pine planted in trench furrows showed a trend of reduced growth relative to the control. Trench orientation was relatively unimportant, but there was a slight advantage to avoiding north-aspect planting positions. Although broadcast burning alone did not have a significant effect on pine growth, it consistently interacted with disc trenching to produce a mild magnification of responses to that treatment. Pine planted in long, narrow, intensely burned windrow strips were consistently larger than control pine throughout the 25-year assessment period, but they had poor form due to being essentially open-grown.
