“a new analysis of 621 wetland sites shows that, on average, restored wetlands regained only about three-quarters of their original biological performance. In restored wetlands, plants, insects, and animals do not reach their former abundance, density or diversity. Wetlands are also excellent carbon storage facilities: They hold at least a quarter of the world’s land-based carbon, according to the World Resources Institute’s Millennium Ecosystem Assessment. But restored wetlands hold less carbon—on average, 23 percent less than untouched wetlands”
