White-tailed deer overpopulation affects not only Northern Virginia, but the whole continental United States. We chose to focus our study on determining how deer group in proximity to water, as this information could be used to control deer populations. Although the assumption that deer group more around water seems logical, in our research we found that previous studies failed to elaborate on the specifics of deer distribution relative to major water sources as well as lacking focus on white-tailed deer (the species of deer currently overpopulating Northern Virginia). We hypothesized that there would be more white-tailed deer, or Odocoileus virginianus, around water sources. To study this topic, our group conducted field tests in Elizabeth Hartwell Mason Neck National Wildlife Refuge, located in Lorton, Virginia.
