Anacortes in Skagit County, Washington — The American West (Northwest)
THE NATURAL DYNAMIC
Ship Harbor was formed by natural forces over thousands of years. It is maintained as a natural landform by the continued dynamic balance of these same forces. Preservation of this area requires that physical, chemical, and biological interactions continue uninterrupted.
The beach is composed primarily of sand, silt, and mud, which is characteristic of a semiprotected bay. The currents and wave activity in the area result in a net eastward drift of water and nearshore sediment. Shannon Point, to the west, protects Ship Harbor from high energy tidal and wave action and prevents finer grain sediment from being washed away. The extensive eelgrass meadow below the shallow waters of Ship Harbor also serves to dampen wave and current energy, further helping to maintain and stabilize fine beach sediments.
Physical and Chemical Factors
A. Long ago, Ship Harbor was a much larger cove, probably extending back through the marsh to the hillside.
B. Over time, sediment was swept into this area from currents along the shore
C. Today, salt water will enter the marsh only when certain extreme conditions occur simultaneously, such as very high tides, extreme low barometric pressure, and strong northerly winds. Typically, the water in the marsh is slightly brackish, measuring two to four parts per thousand (0.2% to 0.4%) in salinity.
THE LIVING SYSTEM
Ship Harbor is a natural embayment which contains highly diverse yet interrelated plant and animal species. The common thread linking all of these species is water - fresh, salt, and brackish. How these species interact depends largely on how each relates to and utilizes the water resources encountered here.
Eelgrass (Zostera marina), a seegrass that flowers and pollinates under water, forms an extensive bed (approximately 23 acres) at depths of one to fourteen feet in the offshore waters of Ship Harbor. Eelgrass is one of the richest types of habitat to be found in Puget Sound, providing habitat for an extensive array of other plants, as well as animals.
The sedge/cattail wetland, or marsh habitat is a transitional area between the higher uplands and the open water. This area is extremely productive and of great value in the natural food cycle. Dead plant matter (organic detritus) and dissolved nutrients (phosphates, nitrates/nitrites and ammonia) form a complex ecological food chain which results in abundant and diverse plant and animal life.
THE HUMAN DYNAMIC
Ship Harbor is a unique economic resource. Once, this was the site of salmon canning operations. Today, we recognize the economic benefits of preserving wetlands and eelgrass beds to help maintain local commercial fish populations.
The pilings throughout the tidal areas once supported dock loading operations for a large salmon cannery. The rows of posts still found throughout the marsh were used as racks for drying and tarring cotton web used for fish traps. Old cannery "tin piles" may be found
