D.7 Monitoring and Managing Ash (MaMA): How You Can Help Enable Lingering Ash Detection for Resistance Breeding
Although emerald ash borer (EAB) typically kills nearly 100% of mature native ash, a small percentage not only survive, but remain healthy years after the rest of the nearby ash have been killed. These trees, found for every widespread Northeastern species, are known as “lingering ash” and can be used for resistance breeding. The Ecological Research Institute developed the Monitoring and Managing Ash (MaMA) program, which facilitates lingering ash detection through data collection and appropriate management. MaMA has already detected approximately 180 lingering ash, furnishing material for resistance breeding by Cornell University. MaMA features prominently in the Tree Species in Peril initiative led by TNC and the USFS, enabling it to expand throughout New England. This workshop is intended for anyone interested in participating in MaMA by using management, outreach or data collection to enable lingering ash detection – our partners include conservation NGOs, agencies, landowners, community scientists and others.
