What can we do about climate change?
One thing we can do is prepare for it, by working with Mother Nature. At the Alligator River National Wildlife Refuge in North Carolina, where rising seas are eroding the shoreline, the U.S. Fish and Wildlife Service and The Nature Conservancy are giving the Albemarle Peninsula a fighting chance.
Starting with a $1 million grant from Duke Energy, the partners have constructed artificial oyster reefs along the shoreline, planted salt- and flood-tolerant trees and vegetation, and restored freshwater wetlands. The goal is to give the land and its species, such as forest-dependent birds and black bears, time to adapt to sea level rise, increased salinity and other climate change impacts.
“We want to slow the rate of erosion; we’re not going to stop it,” said Mike Bryant, Project Leader for six national wildlife refuges on coastal North Carolina, including Alligator River. “If we did nothing, we think we’d see large-scale change in habitats from forest to marsh, and that means the wildlife dependent on these forest communities would have to find some other place. We’ll have larger expanses of marsh and then that marsh will succumb -- along with the soil that it’s standing on -- to the sea level rise and we’ll see continued, accelerated rates of erosion.”
