Federal marksmen culled 84 white-tailed deer from the Indiana Dunes National Lakeshore during a 10-day cull on the east side of the park in March, officials said Friday.
The hunts were conducted as part of the white-tailed deer management plan for the park.
Officials said 82 of the deer were tested for chronic wasting disease, a fatal neurological disease. All of the results were negative.
The deer were removed from the east side of the park, "because monitoring data in that portion of the national lakeshore has shown that excessive deer numbers have caused unacceptable damage to park resources," the National Park Service said in a release issued Friday morning.
Monitoring will continue and will guide future management programs, officials said, adding that it is critical to minimizing damage to the national lakeshore's diverse ecosystem, which includes rare and endangered species.
More than 5,000 pounds of venison from the cull were donated to the Food Bank of Northwest Indiana. Hoosiers Feeding the Hungry paid for the processing of the meet and managed the donation of about half of the deer.
