3	Modeling the effect of neighborhood competition on tree diameter growth in the Pacific Northwest Coast Range Naing, Htet Lin 08 August 2023 (has links) (PDF) Trees compete for various resources such as sunlight, water, and nutrients, which can be expressed as numerical terms, called competition indices (CI). Competition between individual trees is correlated with their growth and mortality. Therefore, CIs are used as independent variables to develop, improve and modify growth and yield models. This study was conducted to test the effect of neighborhood competition on tree diameter growth among Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), western hemlock (Tsuga heterophylla (Raf.) Sarg) and red alder (Alnus rubra Bong.), in the Pacific Northwest Coast Range, USA. After testing seven distance-independent CIs and three distance-dependent CIs, only the distance-independent CIs were found to significantly affect the diameter growth model. Among them, CIs with basal area and diameter information were the most impactful. As a result, a simple CI was very effective in a model that accounts for the basal area information of different tree species. growth and yield models diameter growth models neighborhood competition competition index carbon biomass Douglas-fir western hemlock red alder Pacific Northwest Coast Range Forest Biology Forest Management Forest Sciences Other Forestry and Forest Sciences
