Ell Pond is the one site within the state of Rhode Island that has been designated a National Natural Landmark. Natural features represented at this site include a kettle hole pond and a floating, sphagnum-ericaceous bog mat, bounded by Atlantic white cedar swamp and steep, glacially abraded granitic monadnocks. The site affords a unique opportunity for study, due to the presence of both hydric and xeric plant communities. Designated a NNL in 1974, the site is owned and managed by Rhode Island Audubon Society and The Nature Conservancy.
