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 virtual workshop will be led by Jonathan Rosenthal, Director, Ecological Research Institute and Dr. Radka Wildova, Senior Scientist, Ecological Research Institute. It is intended for anyone interested in participating in MaMA by using management, outreach or data collection to enable lingering ash detection—MaMA partners include conservation NGOs, agencies, landowners, community scientists and others.   

The virtual workshop will be followed by a field tour. Stay tuned for more information about the tour’s location, date, and time.
