Millersville University Mammalogy Students have been working with Lancaster Central Park to survey their deer population. Millersville students go out at night with park law enforcement officers and follow survey transects to spotlight for deer. Once a deer is spotted, students record the distance to the deer from the transect using laser range finders. Once surveys are completed, students will use this data to calculate a population density estimate. The park will then be able to use these numbers to determine what management strategies are needed to either conserve or control the deer herd.
