Overgrazing by deer is changing the face of US forests

“Scientists in the U.S. Northeast published two studies examining the impact of deer overpopulation on natural ecosystems in early March 2014. Scientists at Cornell University investigated disruptions by large numbers of deer to natural growth in developing forests. University of Pittsburgh researchers showed how large deer populations are causing an increase in garlic mustard, an exotic invasive plant, in forest understory fauna. In both instances, the root problem is overgrazing of native plants by deer that open up more growing space for invasive exotic plants that deer find unpalatable.”
