Ticked Off! A Surprising Connections Between Invasive Plants and Lyme Disease

June 12 @ 6:30 pm - 8:00 pm


Japanese barberry is a non-native invasive shrub that became established on much of the post-agricultural lands of New England in the early 1900s and has since invaded the forests in which we live. Barberry stifles native tree and wildflower regeneration and can alter soil chemistry. Ten years of research has revealed there is a positive association between Japanese barberry infestations and blacklegged (aka “deer”) ticks and the causal agent of Lyme disease they are infected with. Japanese barberry is a scourge on the landscape and is detrimental to the health of Connecticut’s forest and citizenry alike.

This presentation will be led by Scott Williams, a wildlife biologist. He has been working specifically with overabundant white-tailed deer herds and their impact on native and managed ecosystems, orchards, gardens, and landscape plantings. He is also knowledgeable about other Connecticut wildlife including songbirds and other migratory birds, game birds, small and medium sized mammals, and fish. His current research includes a collaborative study investigating the best combination of treatments to successfully reduce blacklegged tick abundances and associated disease risk in residential areas in Fairfield County, CT.
