A major flood control dam was completed on the Green River in 1963, and the lower river has an extensive levee system. Puget Sound includes some of the country's busiest ports, including Seattle, Tacoma, Anacortes, Ever… Large wetland systems, nestled in morainal troughs or in the depressions of ancient kettle lakes, dot the landscape and small lakes and ponds can be found throughout. The Puget Sound region in Washington State is home to over four million people. Ecoregions provide a useful framework and background for the discussion of marine, freshwater, and terrestrial environs of the county. Revised 3 November 2020. In the Snoqualmie, agricultural use required only the construction of revetments and a few levees but no major dam. More than one-third of U.S. fish and wildlife species are at risk of extinction in the coming decades. Some species may be able to respond to sea level rise by finding other habitats or food sources, but others will not. A few remnants of the original forest are scattered throughout the eastern edge of this ecoregion. Sea level rise is likely to have a ripple effect that's felt by wildlife and people alike. Seattle, WA 98195 . The result is rising sea levels. In addition, hundreds of thousands of people come to the sound for its wildlife, natural beauty, and recreation opportunities, such as boating, kayaking, whale watching, and fishing. The Western Hemlock zone now consists largely of managed forests. Although these three species have been the first listed, virtually all the salmon, trout, and char species (with the possible exception of Pink salmon) of King County have declined in abundance and distribution over the last 100 years and the potential exists for further listings. Prepared for International Council for Local Environmental Initiative. UW Mailbox 359570. Puget Sound's climate, extensive shoreline, nutrient-rich waters, and diverse habitats sustain a variety of wildlife. Included in these deposits are dense glacial till (hardpan), glacial outwash (clean sands and gravels) and glacial lake sediments (silts and clays). More factors are at work in the salmon declines than landscape change and habitat degradation, however. Even as these buffers have increased in width and breeding areas are protected, the greater landscape continues to fragment. Over the last 2,000 years, sea levels did not change significantly. Lake Washington and Lake Sammamish, King County’s two largest lakes, lie within the CP lowlands; each has an extensively developed shoreline, and little native habitat remains intact amid retaining walls, bulkheads, docks, and lawns to the water’s edge. There are only 15 Level I ecoregions across the entire continent, and King County falls within 2 of these: Marine West Coast Forests and Northwestern Forested Mountains. This sentiment can be heard by Charles Prosch in his description of the Seattle area and Puget Sound Lowlands during 1860. Protection of biodiversity in King County occurs mainly at the habitat level through the use of restrictive regulations and covenants within recent developments. In King County, there are nine Level IV Ecoregions (see Table 2 and Landscape Diversity Map). Working in concert with local conservation groups, it is in this area that much of the County’s land acquisition and protection is directed. Truly a transition zone, this area was probably rich in species and in complex forest habitats that differed because of slope exposure, soils, and fire history. A Puget Sound village of 200 years ago would have been impressive, but not as colorful for an arriving visitor as those of the Haida or Tlingit to the north. The geography of the Puget sound lowlands is mountainous and quikly elevating. Douglas-fir, western redcedar, and some white pine were present in the lowlands, and these species transitioned to a mix with some silver fir and noble fir upslope. Climate change is melting glaciers and ice fields and heating ocean waters, causing them to expand. Prepared for International Council for Local Environmental Initiatives (ICLEI), Biodiversity Initiative. Together, these high- a… Changes in tidal wetlands could diminish the capacity of those habitats to support salmon, particularly young Chinook and chum salmon. In the lowlands of King County, from the shores of Puget Sound to the uplands and foothills of the Cascades, the once-continuous forests of Western hemlock, Western Redcedar, and Douglas-fir have largely been replaced with forest plantations, farms and fields, cities, towns, and their suburbs. The “Tip Top” timber sale auctioned off the rights to clear-cut five 100-year-old forests adjacent to … This ecoregion should also be considered a transition zone for land use as well because the intensity of settlement declines from west to east across the ecoregion. Like the Puget Lowland, the Eastern Puget Uplands have been altered considerably from their past condition. Few areas remain undeveloped along the mainland shoreline of King County; Elliott Bay, for example, is the main harbour and industrial area for Seattle. Plant and animal species have either retreated to these areas as the landscape has been developed or are survivors of the past alterations of the landscape. Department of Ecology, State of Washington The lower Green has seen considerable urbanization with residential and commercial land uses replacing the agricultural areas over the past 25 years. Anywhere, any time. Yet even this area has no completely undisturbed shoreline remaining. Puget lowland forests The Puget Lowland Forests occupy a north-south depression between the Olympic Peninsula and western slopes of the Cascade Mountains, extending from across the Canadian border to the lower Columbia River along the Oregon border. Experience Puget Sound Water Sports and Adventures Washington State, in all its glory, is blessed with rivers that flow from the Cascade Range into hundreds of lakes before meeting the Salish Sea.This gift is keenly felt by Snohomish County locals who enjoy all that the Puget Sound water sports have to offer: swim, raft, fish, and propel across the waters on kite boards, jet skis, boats and tubes. Level III regions describe smaller ecological areas nested within level II regions. Based on 2002 landcover data, approximately 710 square kilometres (274 square miles) of urban area lie in the county, and nearly all of it is in the Puget Lowlands. Ditch the disposables and make the switch to sustainable products. to 800-acre watersheds) in the Puget Sound lowlands of western Washington. It is located along the northwestern coast of the U.S. state of Washington. Among the first area to be logged and turned to agriculture, this ecoregion would also be unrecognizable to the first explorers or to the 18th Century Native American inhabitants of King County. 2007. Uniting all Americans to ensure wildlife thrive in a rapidly changing world, Inspire a lifelong connection with wildlife and wild places through our children's publications, products, and activities, National Wildlife Federation is a 501(c)(3) non-profit organization. The series of studies reported here grew out of conversations with Daren Baysinger, Environmental Compliance Manager for the City of Redmond and Alan Johnson, Natural Systems Design, Seattle, Washington. The Governor of Washington who took the Native Americans' land. There are 52 Level II ecoregions, and the two that occur across King County correspond identically with the Level I ecoregions: Marine West Coast Forest and Western Cordillera. Puget Sound is a sound of the Pacific Northwest, an inlet of the Pacific Ocean, and part of the Salish Sea. 102 pp. Coastal bluffs are the primary source of beach sediment along the Puget Sound shore, and their natural erosion is essential for maintaining beaches … The Puget Sound Lowlands, or the I-5 Corridor, is the most populated region of Washington. However, the forests that are present today are much less diverse in species, age, and size, which are characteristics of the vertical and horizontal complexity of mature stands. Although little irreversible change has occurred here, the landscape bears little resemblance to that first encountered by settlers. Table 2. Join our conservation army. Beds of seagrass, called eelgrass, are spawning grounds for herring, important corridors for migrating salmon, and a food source for waterfowl. Underwater plants provide food, breeding areas, nurseries, and resting places for wildlife in the sound. President and CEO Collin O’Mara reveals in a TEDx Talk why it is essential to connect our children and future generations with wildlife and the outdoors—and how doing so is good for our health, economy, and environment. Isaac Stevens. ». Puget Sound Ecological Burn Program Within sight of the Capitol lies some of the last fragments of lowland prairie and oak woodlands in Western WA. Beginning about mid-October, a semi-permanent low-pressure cell, commonly called the Aleutian Low, intensifies and migrates southeastward over the Aleutian Islands and Gulf of Alaska. As a result, large-scale, landscape ecosystem biodiversity, as represented in the ecoregion discussion, has declined more dramatically than either habitat or species biodiversity, and many habitats, especially wetland, stream, and forest habitats, have been compromised by the effects of land use in the surrounding landscape. King County biodiversity report. Black bear and cougar, now sharing their foothill habitats with more people, are seen in backyards and along trails (see Mammals discussion below). RCPP funds are designated to help improve water quality in Dungeness Bay, where recreational and commercial shellfish harvesting is shutdown seasonally due to poor water quality. The discussion of ecoregions is based on U.S. Environmental Protection Agency (EPA) ecoregion conventions, which result in units similar to European biogeographical regions because they denote areas of general similarity in ecosystems.
