When white-tailed deer populations become overabundant—often due to a lack of natural predation or insufficient hunting—they can cause significant ecological and human-related damage:

Forestry and Agriculture: Overabundant deer cause severe damage to crops and forest ecosystems by overgrazing on cultivated vegetation, orchards, and native plants.1
Public Safety: High population densities lead to an increased frequency of collisions with vehicles, resulting in significant property damage and human injuries or fatalities.1
Disease Transmission: Deer contribute to the spread of dangerous transmissible diseases, such as Lyme disease.1
Impact on Other Wildlife and Livestock: The white-tailed deer carries parasites that have seriously depleted populations of other species, including moose, elk, and woodland caribou, while also negatively affecting livestock.1

Managing these populations is essential to maintaining ecological balance and protecting human health and safety.
