Cultural ecosystem services (CES), one of four main categories of ecosystem services, are often described as the non-material benefits that humans receive from their interactions with the environment.

This webinar discussing economic valuation of ecosystem services was the result of a 2010 Collaborative Research project that studied ecosystem service valuation of southern Maine watersheds.

This survey, prepared and administered by a 2010 Collaborative Research project team in Maine, asks for residents' opinions about how riparian land is managed in the Merriland, Branch Brook, and Little Rivers Watershed.
