Meet the Blue Ridge PRISM Team
Elizabeth Mizell, Executive Director
Beth comes to Blue Ridge PRISM having been actively involved in cooperative weed management areas in Florida and Indiana. In those organizations, she served in key leadership roles gaining valuable experience in organizing and operating CWMAs and insights into the potential for CWMAs to make a big impact on conservation. Prior to moving to Virginia in 2016 and starting a small business, Beth was a Land Steward with The Nature Conservancy for 14 years caring for natural areas and restoring rare natural communities. She has extensive experience in natural areas management and restoration, invasive plant species management and control, native plant propagation, and gardening/landscaping with native plants. Beth is a Level 1 Chesapeake Bay Landscape Professional and holds a license as a Virginia Commercial Pesticide Applicator.
As Executive Director, Beth manages the day-to-day activities of PRISM, fosters relationships with conservation partners, teaches and assists landowners, and manages fundraising.

Jim is a retired organizational consultant. Twenty years ago, concerned about the link between widespread degraded habitat and declining bird populations, Jim began working on introduced plant invasions in natural areas, first with private properties and public parks in Northern Virginia, and since 2013, on his and Susan Roth’s 156-acre property on the lower slopes of the main Blue Ridge in Greene County. The beautiful property had significant invasions of Japanese stiltgrass, multiflora rose, wineberry, Japanese honeysuckle, smartweed, perilla, and others, largely in portions of 110 acres of forest, and more species in fields and open areas. Jim has taken the knowledge and experience gained in Northern Virginia projects and applied them on a landscape scale in Greene, and used that experience to work on county, regional and statewide scales with the Blue Ridge PRISM.
Jim is a Master Naturalist, Tree Steward, a member of the Virginia Noxious Weed Advisory Committee, and Board Member of the Virginia Native Plant Society. Jim serves on the Blue Ridge PRISM Board.
Amy is an ecologist and has a Ph.D. in Environmental Studies and Policy. She is the Program Director for Virginia Working Landscapes, a Smithsonian program that promotes the conservation of native biodiversity and sustainable land use through research, education, and community engagement. In this role, Amy leads a team that cultivates a dynamic network of private landowners, citizen scientists, NGOs, state agencies, and research scientists to collectively investigate the impacts of conservation management and land use on biodiversity.
In addition to research, she is committed to developing a strong outreach program that communicates research findings to inform best management practices for regional conservation partners and the community. An avid birder and outdoor enthusiast, Amy resides on a farm in Fauquier County immersed in grassland bird habitat with her husband Eric and a flock of chickens.
Tim has a master’s degree in forestry from the School of Environmental Science and Forestry at Syracuse University. Upon retiring, he took Tree Steward training in Arlington, VA, to become an amateur arborist and became knowledgeable of non-native invasive plant threats to trees. He did invasives treatment work in Northern Virginia, then moved to the Charlottesville area and joined the Charlottesville Area Tree Stewards in 2011. As a volunteer on the grounds crew at Monticello, Tim removed English ivy from over 2000 trees and then expanded to a wider range of invasive plant treatment, mainly in public parks and open spaces. He joined the Blue Ridge PRISM at its inception and trains on invasive plant identification and treatment for PRISM and for Tree Stewards.

Together with Jake, they organized the first CWMA to be formed in Virginia in 2014, now known as Blue Ridge PRISM.
Rod serves on the Blue Ridge PRISM Board. He is also on the Board of Directors for the Virginia Chapter of the American Chestnut Foundation, the Noxious Weeds Advisory Committee for the State of Virginia, which recommends changes to the state’s Noxious Weeds law and regulations, and the Advisory Board for the VA Forestry Association’s Board of Directors.

Mike Wenger is a Certified Master Naturalist, with the Old Rag Master Naturalist Chapter and works extensively with a variety of public organizations and schools on invasive plant control and replacement. After a 30 year career that spanned industry, the USAF, international business consulting, and university teaching, he retired and spends much of his time working on wildlife habitat maintenance and restoration issues. He is particularly interested in liberating native forest plants from invasive competition to bolster healthy ecology and habitat for insects, amphibians, birds, and mammals.
