    Ecological Steward Skills Training: WREN

    More

    Independence Lake County Park, 3200 Jennings Rd, Whitmore Lake, MI 48189,

    The classes are good for both the beginner who has a few invasives in their yard as well as experienced stewards looking to broaden their knowledge base.

    These classes will focus more on invasive species removal education and conversation than typical restoration workdays. Participants will learn the fundamentals of identifying and managing woody invasives. Participants will gain practical field experience in effective techniques; both with and without herbicide.
