Scientists and investors are restoring a 23-square-mile tract of peatland in North Carolina to help curb climate-warming emissions and restore native habitat. Ditches have drained water from thousands of years of accumulated peat, leaving the site vulnerable to drought and wildfire and unleashing huge volumes of carbon dioxide. One-third of global carbon is stored in saturated peatlands, more than all forests combined. But that reverses when peatlands are damaged. Pantheon Regeneration plans to restore the water table to curb emissions, then sell carbon credits to help fund its goal of preserving a million acres of peatland from Virginia to Florida.
