WINTER 2016 Wetlands VOLUME 8 ISSUE 2 Richard Wilhelm Richard WATER Water is essential to sustain all life. It is equally important to humans as the natural landscapes that sustain us. Conservation and protection of water may be one of the greatest challenges of our lifetime We forget that the and of our children and future generations. While the amount of water on the planet today is the same water cycle and the as it was in prehistoric times, the demands for it have increased. ❚ Land and water are inextricably life cycle are one. connected. We must understand and acknowledge their interdependency and relationship as we develop Jacques Cousteau and implement strategies to conserve water. ❚ Wetlands, vital to the health of our environment, support Oceanographer conservation of the land-water connection. Their irreplaceable role is the result of the unique natural characteristics of wetlands. Like kidneys, they absorb, filter and recirculate our water. Which in-turn provides critical fish and wildlife habitat to so many of the iconic species we identify with Oregon. In the face of destructive floods, they serve as natural buffers helping to protect our communities. ❚ With the heightened awareness around limited water resources, wetlands role in cleaning and recharging our water supply has become even more essential. OREGON’S GREATEST WETLANDS Every year in early winter, high tides in Oregon are higher than usual. These extreme high tides, commonly called “King Tides,” occur when the moon is closest to the Earth. King Tides visually demonstrate what an estuary might look like as the sea level rises. TWC is sharing our King Tide aerial photos to jumpstart conversations about what lays ahead for the future of our estuaries and how sea level rise may necessitate Location changes in land use and infrastructure. PACIFIC CITY Oregon Coast freshwater wetland habitats include deflation plain wetlands, sphagnum bogs, and lakes formed by small creeks that have been blocked by moving sand dunes. Sphagnum bogs, like TWC’s Ian Nedry Peterson Preserve typically occur in depressions and in coastal headlands with Blacklock soils where water is “perched.” Species present in these communities include pitcher-plant, cottongrass, and yellow pond-lily.

COASTAL FRESHWATER WETLANDS Willamette Valley Wetland prairies are seasonally flooded ecosystems dominated by herbaceous plants. In response to restoration of fescue fields, thousands of native prairie plants, including some rare species have turned Mud Slough Wetland Preserve into a tapestry of color and texture. Every fall through spring, thousands of ducks and geese, shorebirds and swallows return to the wetlands. In addition, bitterns, rails, herons, and egrets feed in the marshes, while bald eagles and northern harriers work the skies overhead. 2 MUD SLOUGH, WILLAMETTE VALLEY WET PRAIRIE The Harney Basin is an arid landscape. The supply of water is a limiting factor for most human activity in the basin, as well as for wetlands and their dependent species, such as White-faced Ibis, Avocets and Stilts. Precipitation is variable from year to year and runoff may vary within the same year, resulting in both drought and surplus years, and everything in between. BOCA LAKE, MALHEUR WILDLIFE REFUGE Oregon’s 22 major estuaries are ecologically essential for many fish and wildlife species, includ- ing salmon, crabs, oysters, clams, wading birds, ducks, geese, shorebirds and harbor seals. Management of our Lower Yaquina Preserve allows for migration of plant communities and change in vegetative species composition resulting from flooding, erosion, tsunamis and sea level rise. LOWER YAQUINA ESTUARY PRESERVE What would Tualatin look like today if Althea Pratt Broome had not lead a community movement to save the 56-acre Hedges Creek Marsh? Thirty-seven years later the community conservation in Tualatin has inspired a state wide movement to conserve Oregon’s Greatest wetlands.

Volunteers assisted with preserve maintenance, stewardship and monitoring, scientific data collection, sharing photos and stories, being TWC ambassadors, office work, helping at events and participating on board committees. TWC staff and Oregon wetlands thank you for your time and passion. For the past two years TWC has partnered with Light Hawk Volunteer Pilots on our King Tide (highest tides of the year) to get an aerial look at how Oregon Cen- tral Coast estuaries might respond to rising sea levels. This spring pilots provided us with the 1,000-foot perspective of the land, wetland and water connection of the Harney Basin. Drone pilots have been helping us document the presence of beaver and changing water levels at our preserves. 4 LAND MANAGEMENT/STEWARDSHIP OREGON’S GREATEST WETLANDS Removal of 1400 ft Dike Improves Fish Access to OUR MISSION Poole Slough To partner with Inter-tidal salt marshes are among the most communities biologically productive natural ecosystems on earth because of the way marsh plants live, die, across our state and decompose.

It was a fabulous afternoon of delicious food and drink, catching up with old friends and making news ones and learning about TWC’s most recent projects and partnerships.

In fact, the North American Beaver create wetlands, spawning and rearing habitat for salmon and steelhead, and habitat for insects, birds and amphibians. Their pools help filter water and moderate fluctuations in water flow downstream. They are nature’s hydrologists!
