Researchers used results from a set of replicated experiments on the local impacts of deer to evaluate
the extent to which such impacts account for half-century shifts in forest plant communities across the
upper Midwest. Researchers surveyed seventeen deer exclosures. The Friends research grant funded
surveys that were conducted at Peninsula State Park’s three deer exclosures.
Data analysis indicates that the eating habits of white-tailed deer are the cause of at least 40 percent
of flora species changes in the forests of northern Wisconsin and Michigan over the past 60 years.
