A draft policy on plantings on town-owned property in Ridgefield is being reviewed by the Board of Selectmen.  The purpose of the native plant policy is to allow only native species, and remove all non-native invasive species, which backers say  have a negative impact on the ecosystem.  At the Board's September 7th meeting, there was a discussions about the pricing of native vs nonnative plants, why the policy lists both New York and Connecticut invasive species, and the reason for an exception at Ballard Park. The Board of Selectmen will review the policy and provide feedback.
