Abstract: An overabundance of herbivorous white-tailed deer (Odocoileus virginianus) may have a negative effect on the abundance of native spring ephemerals in urban southwestern Ohio. In some Cincinnati parks bow-hunting or sterilization is used to manage deer populations. The efficacy of this practice is difficult to assess, as deer populations are very mobile and can live in thick growth, making sampling difficult. Our study seeks to investigate whether these management techniques affect the abundance of spring ephemeral plant species. We placed one camera trap in each park in our study to estimate the intensity of usage by deer. We periodically collected information from the cameras and moved them to different locations. Using a combination of these camera traps as well as transect-quadrat sampling to estimate the abundance and diversity of spring ephemerals, we will compare bow-hunted parks, parks with a sterilization program, and parks that do not manage deer populations. We hypothesize that spring ephemeral abundance and diversity will be negatively related to the intensity of deer usage. We further hypothesize that intensity of deer will be lower in managed versus unmanaged parks. We will continue to collect data throughout the season.
