There is presently little visitor <br /> pressure except occasional hunters. A small unpaved road, parking lot and about 500 feet of <br /> fence - is at the northeast corner. In addition a significant trail is planned connecting the parking <br /> lot to the ODOT site. A channel created to protect the site from water -borne invasive plant seeds <br /> has been constructed and must be maintained. (If this source is removed, costs of maintaining <br /> the channel may be deleted.) Patrolling for hunters and other activities not permitted on the <br /> preserve, maintenance of the trail and trailhead, some materials for visitors, maintaining and <br /> replacing equipment are some of the additional tasks on this preserve. <br /> Site Specific Activities - STEWART <br /> Background - <br /> The Stewart Complex has been completed and no additional restoration activities are expected. <br /> There are four water features including Grimes Pond, Stewart Pond, Teal Slough, No Name <br /> Pond plus the pond in the East Stewart property. Although the project is complete, there are <br /> significant populations of invasive species in the wetlands area for which continued control <br /> activities are needed. The cover of introduced species is moderate to high in the original Stewart <br /> Pond and expanded emergent wetland. But the effort to expand the existing riparian woodland <br /> along the edge of Teal Slough is progressing well. The upland at the Stewart Preserve is oak and <br /> ash woodland. There are no rare plants. <br /> 05/08/01 6 <br />
