The Little River Watershed is one of the least developed and most protected in southern Maine. Much of the land has been designated as conservation land, including the the large salt marsh estuary at the river's mouth, which falls within the Rachel Carson National Wildlife Refuge. The extensive blocks of undeveloped forestland and estuary provide habitat for rare and important species including the endangered Black Racer and the Saltmarsh Sharp-tailed Sparrow. Additionally, the sand dunes adjacent to the two swimming beaches located within the watershed provide essential nesting habitat for the endangered Piping Plover.
