If we want to reduce the impact in these protected places, lowering carbon pollution is an integral part of the equation,” Wu added.īecause more birds have the potential to move into national parks than move out, public lands will continue serving as important bird habitat despite a changing climate. “Scenarios with lower greenhouse gas emissions result in a lower average bird turnover. “These drastic climate projections underscore the important role our national parks play as habitat for birds, today and tomorrow” said Joanna Wu, Audubon biologist and lead author on the study. But on the high end of emissions-or "business as usual"-Bald Eagles may leave the Grand Canyon during the winter and Mountain Bluebirds may stop breeding in Badlands National Park over the summer. In scenarios with lower carbon emissions there are fewer projected changes found in parks. The low-end pathway incorporates the most stringent mitigation scenario where the high-end represents our current trajectory. The suitability models were then linked to two different trajectories of greenhouse gas emissions representing low and high emissions paths. The study authors analyzed 274 sites managed by the National Park Service and overlaid them with climate suitability models for birds known to spend summers and winters within the parks. The peer-reviewed study appears today in PLOS ONE and delivers another sobering reminder of the threat climate change poses to birds. NEW YORK - According to a groundbreaking study published today by scientists from the National Audubon Society and the National Park Service, on average, 25 percent of the bird species found in some of America’s most well-known national parks could be completely different by mid-century because of a changing climate.
