MONMOUTH — A 273-acre parcel that includes forest, wetlands, open fields and 3,670 feet of shorefront on Annabessacook Lake will be protected forever from most types of development.

Landowners Charlie Jacobs and Rebecca Stanley donated a conservation easement Monday to the Kennebec Land Trust, preventing the land from being developed, other than minor residential development on a 17-acre homestead part of the property, or some agricultural structures elsewhere on the property.
