What factors affect axis deer population on Molokai?

Habitat and Land Use

Axis deer on Molokai inhabit a mix of grasslands, shrublands, and forests. The island’s terrain and climate create a mosaic of suitable habitats that support a stable deer population. However, human activities such as agriculture, urbanization, and infrastructure development can fragment habitats and create barriers to deer movement, affecting population dynamics. In some areas, invasive species like feral pigs and rats compete with deer for resources.

Disease Transmission

Disease transmission is a significant factor affecting axis deer populations on Molokai. Chronic wasting disease (CWD) and other diseases can have a profound impact on deer populations by reducing their numbers and altering behavior. Effective disease management strategies, such as surveillance and testing, are crucial to mitigate the risk of disease transmission among deer.

Hunting Regulations and Management

Hunting regulations play a vital role in managing axis deer populations on Molokai. The Hawaii Department of Agriculture and the US Fish and Wildlife Service work together to establish hunting seasons, bag limits, and other regulations that balance deer management with conservation goals. Effective hunting management strategies can help maintain a healthy deer population by controlling numbers and promoting sustainable hunting practices. In 2022, the state of Hawaii implemented a new hunting season for axis deer on Molokai, which helped to reduce deer numbers and alleviate concerns about overpopulation.
