Correlation of Quercus species regeneration to edge effects and light availability in Oak-dominated forests.

Oak (Quercus) species abundance in the forest are most likely affected by many factors. Overgrowth due to fire suppression, pathogens, climate change, and light availability are a few possible culprits which have been found in the literature. This study focuses on whether light intensity is correlated with canopy density to have a significant affect on Oak species growth. Three different small-scale forests within the Des Moines, IA city limits were tested for edge effects on light intensity over a period from October 2014 to July 2015. Changes in light intensity were then compared to three separate Quercus specie’s life stage abundancy (seedling, sapling, and adult trees). Expected results are that light intensity deteriorates more rapidly when it is measured farther away from the forest edge, and that this will have adverse effects on the growth of saplings and may even contribute to early death of the trees. Then when canopy trees die, there will then be few intermediate-stage Quercus sp. to colonize in their place. Quercus species are extremely important as a food and shelter source for many wildlife species. It would be detrimental to the biodiversity of ecosystems if Oak trees cannot keep up with regeneration rates of invasive species. New management plans need to be considered and implemented in order to conserve Oak dominated habitats for the future.
