Session 14. Discussion Groups

  1. Tools & Techniques: Ask the Invasive Plant Management Experts – Whether you’re curious about ways to control a particular plant, need to know how to plan for an unusual situation, or need guidance on strategy, come learn from your peers and get your specific control questions answered by our expert panel of seasoned land managers.
  2. Aquatic and Estuarine Weeds –Water is precious in California, and not only to humans. Water supports wildlife, and aquatic and estuarine environments are especially rich habitats. Come discuss the latest invasive plant management efforts in the Delta, Lake Tahoe, San Francisco Bay and elsewhere. Led by Drew Kerr, Invasive Spartina Project, Gina Darin, Cal. Dept. of Water Resources, and David Kratville, Cal. Dept. of Food & Agriculture
  3. UAVs and Helicopters – Come discuss what land managers need to know about incorporating these flying tools into their management programs. Led by Julia Parish, Catalina Island Conservancy and Morgan Ball, Wildlands Conservation Science.
  4. Communications Strategies – Whether communicating with volunteers, decision makers, the media or the public, we need to ensure that our message is as effective as possible. Studies find some counterintuitive things about how people understand issues. We’ll talk about communication planning for invasive plant management programs, including hot-button issues like use of herbicides and tree removal. Led by Doug Johnson, Cal-IPC and Rachel Kesel, OneTam.
  5. Non-Chemical Approaches to Invasive Plant Management – Much of invasive plant management is done without the use of herbicides, but there are few comprehensive guides to best practices for using the wide range of non-chemical approaches. Managers need to know which techniques work—and don’t work—in which situations, and so do decision makers who face public scrutiny. Come hear about the current effort to compile best practices for non-chemical approaches and share your expertise and perspectives. Led by Andrea Williams, Marin Municipal Water District, and Cheryl Wilen, University of California Cooperative Extension.
