Japanese barberry (Berberis thunbergii), a common ornamental shrub, is also fairly common in wooded areas of the Federal Farm and Gully Road properties. It is ranked #4 in invasiveness for the Northeastern area by the US Forest Service, and is on the New York DEC’s list of prohibited species. So “no person shall sell, import, purchase, transport, introduce or propagate” Japanese barberry or “knowingly possess with the intent to” do those things.
Besides the usual litany of problems ascribed to invasive plants, Japanese barberry is thought to provide an especially good environment for blacklegged (“deer”) ticks (Ixodes scapularis), which can carry a number of harmful microbes, including Borrelia burgdorferi (the bacteria that cause Lyme disease).
Barberry isn’t as prevalent at the Conservation Area as some of the other invasives, but it’s not hard to find. It’s most noticeable in more heavily-wooded undersories.
