Invasive pests are a growing threat to the health of forests both in the American Northeast and other regions of the world. How can we address this critical problem effectively? In a February 2025 talk presented in conjunction with the opening of the Mann Library Gallery exhibit, "Invasive Species: A Collaborative Exhibit," Grace Haynes of the New York State Hemlock Initiative (NYSHI) presents an overview of what is currently known about key invasive forest insect pests in the northeastern United States, focusing primarily on the devastating hemlock woolly adelgid (HWA) and its impact on our native hemlock forests. NYSHI has spent many years investigating the management of HWA, and there are important insights to share from this frontier in science. Communication and human imagination also have key roles to play in finding solutions, and Cornell professor of soil science Johannes Lehmann, a founding member of the vibrant art, science and sustainability collaboration space known as The Soil Factory in Ithaca, N.Y., reflects on the new perspectives and fresh ways of thinking and engaging that emerge where science and the fine arts meet.This talk was hosted by Mann Library and the Department of Natural Resources and the Environment at Cornell University.
