The Shillapoo Wildlife Area (SWA) was initially approved as a BPA wildlife mitigation project in 1996 and was re-approved for funding in 2002 as part of the Northwest Power Planning Council's (NWPPC) Provincial/Sub-Basin Planning Process.  This project is located in the Lower Columbia Province (Lake River Sub-Basin) and partially addresses wildlife losses due to adverse impacts caused by construction of Bonneville, The Dalles and John Day dams.  Land acquisition and management programs to meet mitigation objectives have been under way since 1996 on the SWA.  Continued operation, maintenance and enhancement activities funded by BPA are necessary to maintain and enhance wildlife habitat benefits and to ensure BPA's mitigation obligation is met.

Ongoing maintenance and enhancement work includes restoration of approximately 650 acres of wetland plant communities within the drained Shillapoo Lakebed and management/enhancement of other smaller wetland basins throughout the wildlife area. This primary enhancement focus is envisioned to provide wintering habitat for Canada geese, other waterfowl and sandhill cranes while increasing the overall habitat and wildlife diversity in the area.  The results of an emerging feasibility study could possibly change the management scheme for some of these wetland areas by reestablishing direct hydrologic connections with the Columbia River with the intent of providing benefits to out migrating juvenile salmonids.  It is somewhat certain that this alternative approach will result in lower quality habitat for some of the target wildlife species than we could produce under the current management regime.  To what degree is uncertain and will require close study as potential alternatives are evaluated.

Tree and shrub planting will occur along approximately 1 3/4 miles of riparian zone on the west bank of Lake River and in other areas to restore or improve riparian habitat.  Some of these areas require that exotic vegetation (usually Himalayan Blackberry) be removed prior to planting, making these projects multiple year endeavors.  Tree planting will also occur in selected wetland and Oak habitat to improve habitat conditions for indicator species including Great Blue Heron, Yellow Warbler, mink and other species.

Other ongoing maintenance activities include fence maintenance, noxious weed and brush control, and waterfowl forage improvements much of which is accomplished largely though agreements with cooperating farmers.  Water levels are also managed and moist soil management practices are employed in wetland basins where enhancement has occurred to reduce reed canary grass cover in order to create favorable conditions for native plants.

The Shillapoo Wildlife Area is in an area rich in history in terms of both Native American and Early Settlement of the area.  Included in this year's statement of work, is a project which will begin the process of developing a Historic Properties Management Plan which will help assure that the historical features on the wildlife area are protected as wildlife habitat projects are implemented.  Currently consultation on work plans has occurred annually and development of this plan may help to streamline that process by providing a more comprehensive view of the historical features in the context of ongoing and planned future work.  The project will be accomplished primarily though contracting with a consultant with some of the funds remaining in the Washington MOA account.
