DESCRIPTION
The Point No Point Treaty Council used this funding to assess habitat changes in the Hood Canal and the Juan de Fuca Strait regions of Washington State. They evaluated observed difference between the historic and current time periods and evaluated the potential causes of these changes. Using early topographic maps they identified 250 nearshore habitat complexes (i.e., estuaries, stream mouths,and spit features) across the Hood Canal and Juan de Fuca Strait (SRFB funded the Hood Canal portion while a federal grant funded the Strait portion).
With the aid of a GIS, they used the historic conditions and modern-day air photos to delineate the surface area extent and configuration of tidal wetland habitats associated with these habitat complexes. They then assessed habitat changes observed between past and present and evaluated the potential causes of these changes. In many of the habitat complexes, additional sources of information helped them make determinations about the causes of change. They considered the drift cell and watershed context for alterations to spits and estuarine habitats using additional datasets.
They assigned a "relative condition" rating to each habitat complex based on the percent loss in tidal wetland surface area and the level of impairment of habitat connectivity. The intent of this rating is to give both site- and landscape-scale indications of the level of impairment of tidal wetland conditions.
Based on these analyses, they provided recommendations for habitat protection and restoration across the study area, and they offered recommendations for future studies. They completed their final report, Historical Changes to Estuaries, Spits, and Associated Tidal Wetland Habitats in the Hood Canal and Strait of Juan de Fuca Regions of Washington State, in December 2006 and distributed it to project partners and others working in the Hood Canal, Strait, and greater Puget Sound region.
