Forest management efforts in Connecticut paying off as American chestnut tree makes a comeback | The Republic

• Scientists have been working on restoration since the 1930s, and in the last several years, American chestnut specialist Sandy Anagnostakis has been breeding blight-resistant trees by crossing the American species with its Chinese cousin, which carries a resistant gene.

   

  Some 200 of those blight-resistant seedlings were planted on 2.5 acres at Belding in 2009, and while mortality is eventually expected to reach 50 percent due to die-off from natural competition, Seymour said the vast majority of the trees are thriving.

• Eventually, the native trees will reach maturity and begin cross-pollinating with the newly planted blight-resistant strain, creating seedlings genetically similar to trees native to the site that also carry genes resistant to blight.
