The history of human activity, the local topography, the Mediterranean climate, and changes in wildfire regime have all had a significant impact on the spatial distribution of oak forests in the Sierra Nevada. This study aims to explain the rate of tree fatalities during drought periods by either ecology (e.g., tree density and thus competition) or geography (e.g., environmental variables such as topography). The purpose of this study is to test the following hypotheses that tree death rates are higher on steeper slopes than gradual slopes, that tree death rates are higher on south and southwest facing slopes as opposed to north and northwest facing slopes, and that tree death rates are higher on slopes with higher tree density because of competition between different tree species. This study used UAV-derived imagery taken between 2018-2022 to identify oaks that died during that period at River Ridge Ranch, CA. A mortality analysis of the eastern half of the ranch found that west facing slopes saw the greatest amount of morality even adjusted for tree density. The results also demonstrate that, as a result of competition between various tree species, tree death rates are higher on slopes with higher tree densities. This lends credence to the hypothesis that tree density eventually influences mortality to a greater extent than topography.
