  Citation × Citation Citation Abstract Copy Title: Koll Center Wetlands Natural Resources Maintenance Management Plan Author: Clayton, Meredith Year: 2006 The intention of this plan is to provide a vision and guidelines for maintaining and improving the ecological health of Koll Center Wetlands in the short and long term. Although the plan will change over time, the goal is to quantify natural resource needs spatially, temporally, and economically. Koll Center Wetlands is part of the Greenway/Fanno Creek/Koll Center Wetlands Park complex. The nearly 13 acre park is dominated by aquatic habitats that attract a wide variety of wildlife, particularly birds. The park grounds are not easily traversed and experience limited human use, but there are many viewpoints from which the park is easily and commonly observed by visitors. The park serves as valuable habitat for both local and migratory wildlife as it connects with the many other terrestrial and aquatic habitats of the park complex, forming a large wildlife corridor in an otherwise urban setting. The aquatic habitats respond to fluctuating water levels, creating seasonally diverse habitat conditions that support a variety of birds, mammals, and reptiles. A mixed forest grows on the southern slope of the park, housing a heron rookery and many well-established oaks and conifers. A weir located just past the south border of the property enables the wetlands to provide the services of storm detention and water filtration for runoff from the surrounding business park. Runoff from parking lots and landscaped areas can contain contaminants and nutrients capable of jeopardizing stream health. Settling and filtration of these compounds occurs as water travels north to south in the wetland, making the water that ultimately reaches Fanno Creek cleaner than it began. Since Koll Center Wetlands is located within a highly urbanized area, direct and indirect impacts to the natural areas from the surrounding region are considered in the maintenance management plan (MMP) for the park and its individual habitat units. These include, but are not limited to, direct human impacts, invasive plants and animals, and ongoing natural processes in plant communities.
