Early Results from a Rangewide Green Ash Provenance Test

Two-year-old green ash seedlings from 32 provenances covering 14° of latitude and 32° of longitude in the United States and Canada were outplanted in central Maine. After 4 growing seasons in the field, average survival was 96%. Height varied significantly among provenances, ranging from an average of 98.0 cm for trees from Iowa and eastern Missouri, to 33.2 cm for trees from a provenance in southern Missouri. Trees from the Ohio River valley region generally sustained the most winter damage, while those from other areas suffered little injury due to cold.
