Restoration experts from Ducks Unlimited, The Nature Conservancy, and the Lower Fox River/Green Bay Areas of Concern will discuss case studies of partnerships turning federal GLRI funding into successful on-the-ground habitat restoration projects that provide a variety of ecological and societal benefits that can be sustained well into the future. Featured case studies include successfully restoring coastal marsh for waterbirds and for northern pike, using watershed-based GIS planning tools to prioritize restoration projects, and the reestablishment of the Cat Island Chain of islands in lower Green Bay. This presentation was given by Brian Glenzinski, Wisconsin Regional Biologist, Ducks Unlimited.

- 2. Green Bay West Shores • 70% of wetlands along or adjacent to Green Bay s west shore have been lost
- 3. The reluctant evolution of a Fisheries Biologist
- 4. Typical Wetland Enhancement Design Impoundments with water control structures, managed primarily for waterfowl Sensiba Unit: 1959 Impoundment
- 5. West Shore Northern Pike Habitat Restoration Project • • • • Started - 2007 First projects installed – 2008 36 contracts to date Monitoring YOY started 2011
- 6. Pike Spawning Requirements • Small ephemeral streams and wetlands • Vegetation • Shallow water ( < 10 inches)
- 7. Pike Spawning Projects - Mercier Spring 2011 Fall 2011 Spring 2012
- 8. Project Goals & Accomplishments Goals • 25 Acres – Buffers • 38 Acres – Wetland Creation/Restorations • 6 Culvert Impediments replaced • 5 Miles of new stream accessibility • Increase top predator (pike) # s in Bay • Reduce Green Bay s impaired uses for degraded fish and wildlife populations Accomplished • 50.9 Acres – Buffers • 33.4 Acres – Wetland Creation/Restora • 6 Culvert Impediments replaced • 17 Miles of new stream accessibility
- 9. Ecological Services • 2-3 inch fish = $0.52 AFS • 53,901 YOY captured in 2003 at Barkhausen = $28,028 • Habitat restoration pays for itself quickly
- 10. YOY Assessments Monitoring Results YOY Traps 2011 2000 21 2012 300 23 Note: Heavy snow during fry incubation period in 2011 and drought conditions in 2012 resulted in low spawning success Areas of Concern • Lower Lake Levels • Drought • Flashy nature of spawning wetlands
- 11. Sensiba Unit – Green Bay West Shores • 1,210 acres • Lake MI Coastal wetlands • Wisconsin DNR Ownership • Partnership restoration
- 12. Sensiba Wildlife Area • 1,210 acres • Lake MI Coastal wetlands • Wisconsin DNR Ownership
- 13. L.H. Barkhausen Waterfowl Preserve • Borrow Area • Water Routing • Water Levels Partnership: Ducks Unlimited Brown County Green Bay Packers USFWS Coastal Program
- 14. Benefits of cross discipline collaboration • • • • • • • Cost effective fish access Separation provides optimal waterfowl habitat Water level control provides optimal hydrology during peak spawning periods Ephemeral Pike marshes can provide additional waterfowl habitat during fall migration with increase water level management Increased Ecological Services Increased partner and public support Improved Green Bay Fishery
