Parks studied all available options before deciding on lethal removal as the best option to reduce the deer herd. Two of the options we get the most questions about are Trap/Release, and Contraception. Trapping and releasing is not an option in Ohio. The Division of Wildlife (DOW) does not allow it. The reason is it can be a stressful event for the deer. Over 60% of them die within a year of being relocated. It is not legal and is not truly humane. Contraception is considered to be experimental in the state of Ohio, and can only be approved by the DOW as a research project. The Cincinnati Park Board and the DOW have recently approved a research project to sterilize the deer in the Clifton parks – Rawson/Edgewood, and Mt. Storm. Female deer (does) will be tranquilized, transported to a mobile veterinary facility, and have their ovaries removed. They will be ear tagged for future reference, some will be radio collared to monitor movement. The stated objectives of this 3 year project are to reduce the population and to quantify local immigration rates.
