Emerald Ash Borer Study
Treated ash trees and untreated ash trees, infected one and uninfected one… they all were studied as part of a research project to evaluate emerald ash borer (EAB) control efforts. The study took Tre to Missouri, Illinois, Michigan, Indiana, Kentucky, and Keokuk, Iowa. The method Ash Tree Preservation uses to control EAB is the method the study determined to be best.
Blue Ash Study
Most species of ash trees are dioecious. That means there are female trees that produce seeds but don't produce pollen and there are male trees that produce pollen but never seeds. One exception is the blue ash. It's a monoecious species. It produces flowers that have both male and female parts. The flowers are very small, approximately 3/8-inches tall. They have no showy petals and therefore they're quite inconspicuous. Tre used his field scope and camera to take the photos appearing to the left.
