Elm Species Resistant To Dutch Elm Disease

Q: On my property, there is a mature, healthy American elm. It seems unaffected by Dutch elm disease. Is there a registry that documents surviving elm specimens? 

A: Although American elms have been decimated by Dutch elm wilt, the species is not as close to non-existence as American chestnut. There are still many seemingly healthy specimens growing in Georgia. There is one variety, ‘Princeton’, that seems resistant to the disease. Lacebark elm is similar in appearance and shows no susceptibility. To my knowledge, there is no elm registry but keep up with news and research concerning this fine tree.
