A new Science Update from the U.S. Forest Service Southern Research Station (SRS) provides the latest data on ash tree (Fraxinus spp.) species in Alabama, Arkansas, Mississippi, and Louisiana.
The emerald ash borer, an introduced Asian beetle species first detected in Michigan in 2002, has spread throughout the northeastern U.S. and into the southern states of Arkansas, Georgia, Kentucky, North Carolina, Tennessee, and Virginia. Some stands of ash have experienced up to 99 percent mortality as a result of beetle infestation, impacting not only the ecology of the stands but also the economies of the states where infestations occur.
Current locations of emerald ash borer infestations suggest that the beetle will eventually infest stands in Alabama, Mississippi, and Louisiana.
Using Forest Inventory and Analysis (FIA) data, SRS forester Sonja Oswalt provides the latest data on the extent, net annual growth, and economic contributions of ash in these states and in newly infested Arkansas.
