Restoration and Land Use Concepts coniferous trees and shrubs. Forested wetlands would include deciduous trees such as black cottonwood (Populous trichocarpa), red alder (Alnus rubra), and willows (Salix Sp.). These species are currently found in the subarea in large numbers. Coniferous forested wetland tree species include primarily Sitka spruce (picea sitchensis), shore pine (pinus contorta), and Western red cedar (thuja plicata). Some large specimens of Sitka spruce are growing in the northwest corner of the subarea. Forested wetlands in tidally inundated areas would have their lower limit approximately 2 feet above the high tide line (MHHW). Over time, trees may spread into areas initially lower than this. Non-wetland riparian forested habitat would occur along the slopes of levees and in areas above forested wetlands. This habitat type would include many of the tree species list in forested wetlands, but also include deciduous trees such as big leaf maple (Acer macrophyllum), and conifers such as Western hemlock (Tsuga heterophylla), grand fir (abiesgrandis), and Douglas fir (pseudotsuga menziesil). There are many other species of smaller trees and shrubs that would likely occur in the riparian forested areas. All the riparian forests are an important habitat for fish and wildlife and a source of large woody debris. 4. Tributary Channels: These relatively small channels include perennial and intermittent streams from the adjacent hillsides flowing through the three types of habitat described above. They would provide important habitat for fish including salmonids, and replace the existing ditches with more sinuous, natural channels and with vegetated banks and some large woody debris in the channels. 5. Blind Tidal Channels/Dendritic Channels: These channels would form most readily in the mudflat and tidal emergent marsh habitats. They may extend to the edges of forested wetlands. These channels also provide important access for fish including salmonids. 6. Non-tidal Freshwater/Palustrine Marsh: Freshwater, non-tidal wetlands are referred to as Palustrine in most wetland rating classifications. These wetlands are currently found in many parts of the subarea, and include forest, scrub/shrub, and emergent marsh plant communities. These wetlands would include most of the same plant species as the communities listed above for tidal emergent marsh and forested wetland. One significant difference is that these non-tidal wetlands would have significantly less natural disturbance than tidal wetlands. However, they would be affected by periodic large floods that overtop the dikes and deposit sediment and debris. Palustrine marshes could include tributary channels, but would not include Draft Subarea Plan June 2009 Everett Marshland 38 070346-01
