This unique property offers a beautiful tranquil setting, a rare habitat and an unusual connection to the distinctive human history of the city. The ecosystem of Seine Field is a habitat type known as an “Open Heath” or “Relic Sandplain Grassland,” which is characterized by arid, sandy soil and scarcity of humus-rich topsoil. This habitat type was once common along the Essex County coastline, but is now quite rare in New England. Only the unusual circumstances of the property’s history have kept the Seine Field in this early successional stage of vegetative growth.
