The town of Scarborough and the Scarborough Land Trust have permanently conserved nearly 40 acres of the Willey Recreation Area on Tenney Lane. The area includes ball fields, footpaths, woods and meadows, as well as substantial wetlands and a habitat restoration project for the endangered New England cottontail rabbit, according to a news release from Kathy Mills, executive director of the trust. The property is next to Benjamin Farm, a 135-acre stretch of fields, woods and wetlands on Pleasant Hill Road that the trust bought for $2.5 million on Dec.
