The first stop on Audubon Washington's Great Washington State Birding Trail - Cascade Loop; this marsh hosts up to 90 species of birds during the course of the year. A Bird Checklist for birds of the Edmonds Marsh and adjacent beaches (in PDF format) can be downloaded for free here. After urbanization, the railroad and man-made barriers blocked the tidewater flow. This situation for a time created a freshwater dominated wetland as Willow and Shellabarger Creek's outlet was blocked. In 1988 the saltwater flow was reestablished by opening the tidegate most of the year. As a result the marsh has now reverted towards its former saltwater condition. The cattails have diinished and the site contains diverse wildlife habitat supported by both fresh and saltwater vegetation. |
