In 1995, the land developer of Fenwood, Monetta Properties Inc., donated a conservation easement on 7.3 acres lying between their subdivision homes and the unique Philbrick-Cricenti Bog in New London. The easement land creates a vital buffer zone of conserved land between the homes and this rare "floating" sphagnum bog where the New London Conservation Commission maintains an interpretive trail. The easement was granted to the Town of New London with Ausbon Sargent as the backup grantee*. A public footpath is allowed (but regulated by the easement).

*A backup grantee is an organization that is empowered to enforce an easement if the original grantee fails to do so, or to take over an easement if the original grantee can no longer manage it.
