Rotary Roundup

On Sunday, January 6, arround 60 volunteers gathered at Hammonasset Beach State Park to remove invasive plants from the cedar grove near the rotary. Invasive plants that were removed included Japanese honeysuckle, oriental bittersweet, and autumn olive. The event was cosponsored by Menunkatuck, Friends of Hammonasset, and the Meigs Point Nature Center. Participants were as young as 11 years old and came from as far away as Ellington.
After two hours of cutting and hauling the vines and branches, a luncheon of clam chowder, chili, warm drinks, and dessert were served at the Nature Center.
Our thanks to the volunteers who helped and the following local businesses: Bishop's Orchards, Guilford; Cohen's Bagel Company, Madison; Culinary Concerts, Madison; Friends & Company, Madison; and Lenny & Joe's Fish Tale, Madison.

Japanese Barberry and Lyme Disease

An article in the New London Day describes a link between the invasive Japanese barberry and Lyme disease.

Jeffrey Ward, chief scientist at the Connecticut Agricultural Experiment Station's Department of Forestry and Agriculture, and experiment station scientist Scott Williams have been doing research on the relationship between Japanese barberry, ticks that carry Lyme disease and deer overpopulation.

A highly invasive plant that forms dense canopies in forests - particularly those with high deer populations that eat most every other plant - Japanese barberry also creates moist, cool shelters that harbor ticks that carry the Lyme disease bacteria, Ward's and Williams' research has shown. Hot, dry conditions suppress tick populations.

At 28 study areas, including a parcel along Lord's Cove in Old Lyme, the two have been studying various aspects of the triangular relationship between ticks, deer and barberry, and spreading their message to land conservation organizations about the best methods for ridding forests of barberry. Deer serve as hosts for adult ticks, while the barberry functions as a nursery for ticks in their juvenile stages.

Williams said tick abundance in barberry-infested areas is 67 percent higher than those where native plants are predominant. Also, the percentage of ticks that carry the Lyme bacteria is higher - 126 infected ticks per acre versus 10 per acre in barberry-free areas, Williams said, though the reason for that is as yet unclear. After barberry removal, Ward said, tick populations drop as much as 80 percent.
