Management Implications of Ash Yellows in Northeastern Hardwood Stands
Abstract:This paper identifies management implications for forest stands affected or potentially affected by ash yellows (AshY) based on results from studies on the response of forest structure and composition to AshY and the interrelationship of AshY, drought, and radial growth decline of white ash. Specifically, the synthesis of these studies compares the structure and composition of forests classified as either declining or nondeclining based on patterns of white ash radial growth and identifies the role of AshY in these forests. Data were collected from 41 plots in 6 northeastern states. The incidence of AshY at the stand level was associated with high white ash density and importance value, increased white ash mortality in the upper canopy, stand ages generally less than 60 years, and a high degree of forest fragmentation. The presence of AshY in individual white ash was generally associated with a decline in radial growth. The radial growth of white ash unaffected by AshY could recover from drought stress, but white ash affected by AshY apparently could not. Managers of forest stands having a high white ash density, particularly in droughty stands or in areas with a high degree of forest fragmentation, should encourage greater overstory species diversity.
