Hunting gives deer-damaged forests in state parks a shot at recovery
Date:7/9/2014

e hunting program by comparing the amount of plant cover in 108 plots in state parks and historically hunted areas with 1996-97 levels. They found that total plant cover in state parks more than doubled from 1996-97 to 2010. Herbs such as asters, violets and goldenrods increased from about 20 percent to 32 percent cover, and percent cover of grasses rose from 1 to 3 percent. Tree seedlings jumped from about 2 percent to about 13 percent of total plant cover, a finding that suggests when older trees die out, there will be younger trees to replace them, Jenkins said.

"With heavy populations of deer, tree seedlings often don't have a chance to survive," he said. "In those situations, the forest could lose its ability to reproduce itself and eventually cease to be healthy."

The study also showed that the hunting program led to the recovery of native species and discouraged the spread of invasive and exotic species, said Lindsay Jenkins.

"We saw a striking improvement in the quality and diversity of the forest understory in state parks compared with conditions before the hunting program," she said. "The deer management program is having a clear, beneficial impact on Indiana parks and could serve as a good example for nature preserves with overabundant deer in other states."
