To review, my hypothesis is that trees growing in groups will have a different mortality rate in comparison to those growing in isolation across all aspects of growth. The theoretical basis of my project is that tree density and aspect will effect how successful Douglas-fir trees are. My hypothesis is primarily concerned with aspect of growth and tree density. It might also touch on environmental factors such as precipitation throughfall, competition, and disturbance frequency. My research is underpinned by ideas such as tree-to-tree competition, annual precipitation, and annual hours of sunlight. Some key words that could be used to describe my project are Douglas-fir forest, aspect of growth, and tree density.
