The Emerald Ash Borer has devastated many of our 600 ash trees, requiring us to fell many over the past year. The EAB is an invasive, wood-boring insect that specifically targets ash trees (Fraxinus spp.). The EAB is projected to kill nearly 100% of the 8.7 billion extant ash trees in North America. For more information on the EAB, visit the Iowa DNR page or the Emerald Ash Borer Information Network.
Although the EAB will continue wiping out ash trees, we we will do what we can to minimize the impact of the EAB on the rest of the ecosystem. The open spaces in the canopy will allow sunlight to reach the young oaks and walnut trees, which will eventually establish a new canopy. We continue to plant diverse tree species to ensure that the wildlife will be supported with ample habitat, shelter, and food.
Continued Tree Planting
This spring we have potted and planted 250 trees and shrubs, including hazelnut, high bush cranberry, hibiscus, arborvitae, redosier dogwood, white oak, shingle oak, red oak, paw paw, rose mallow, serviceberry, and pecan.
