Federal scientists now believe there are a few extra hardy ash trees out in nature that have — for reasons unknown — defied the odds and held up against the highly destructive, green metallic beetle from China known as the emerald ash borer.

They want the public’s help in finding those “survivor” trees — and are starting their research in seven northwest Ohio counties and 10 southeast...
