This latest acquisition protects the Preserve’s second-most important physical feature, after its namesake 50-foot feeder bluff, a brackish marsh which is fed by a freshwater drainage from the northeast. This site has been identified by the Washington Natural Heritage Program as one of the top 20 most significant coastal wetlands in the Puget Sound region. The driftwood berm separating the marsh from Hood Canal is breached periodically by winter storms and high tides, introducing a more saline element into the marsh.
