• Habitat Protectors: New Team Targets Invasive Species on State Lands (February 4, 2026)
  • In 2024, Michigan’s Invasive Species Program began assembling a team to focus on emerging populations of new invasive species and tree diseases on state lands. Today, four foresters and two wildlife biologists are hard at work detecting and managing watch list and high priority invasive species on 4.6 million acres of state forests, parks, recreation areas and game and wildlife areas.

As if this weren’t enough, the changing climate is further stressing trees and may lead to greater impacts by both invasive and native insects and diseases. Join forest entomologist Erin Biggs and forest pathologist Simeon Wright of the Department of Natural Resources to learn more about these emerging issues, how they are being addressed, and which may have the biggest impact on Michigan’s forests and urban landscapes.
• Getting down to the nitty gritty: Oak wilt spread and vector behavior research in Michigan (October 29, 2024)
  • Oak wilt is an invasive fungal pathogen that spreads underground through interconnected roots and also above ground by beetles that carry, or vector, the pathogen. Nitidulid beetles, also called sap beetles, act as oak wilt vectors. They are attracted to sap from fresh wounds on trees which become entry points for the fungus. Knowing exactly when these beetle vectors are active in the spring and summer can determine the “no pruning” season recommended to protect oaks. Join Dr. Tara Bal and Katie Bershing from the College of Forest Resources and Environmental Science at Michigan Technological University as they explain how to identify and prevent oak wilt and share results from their ongoing research into oak wilt vector behavior in northern Michigan.
