  1. Aquatic Habitat Restoration in Little Bear Creek Lake Joe Jernigan Aquatic Plant Manager Alabama Wildlife and Freshwater Fisheries

  2. Mission Statement • The mission of the Wildlife and Freshwater Fisheries Division is to manage, protect, conserve, and enhance the wildlife and aquatic resources of Alabama for the sustainable benefit of the people of Alabama.

  3. We Work to Protect The Resource

  4. We Work to Improve the Quality of Hunting and Fishing in the State

  5. Areas that look like this we change to this

  6. Good habitat

  7. Little Bear Creek Reservoir

  8. Little Bear Project • B.A.S.S. • Little Bear Millennium Group • Bear Creek Development Authority • Alabama Wildlife and Freshwater Fisheries

  9. What’s Missing? • Several limitations have likely prevented natural establishment of submersed native aquatic plants in LBCL: • absence of a source of aquatic plant propagules • water-level fluctuation • Herbivory

  10. Approach • Monitor emergent vegetation with the water willow beds present already • Plant native submerged aquatic vegetation (SAV) and evaluate the success

  11. Water willow

  12. hydroseeding

  13. Approved SAV • Valisineria (2 forms), V. americana • Water stargrass, Heteranthera dubia • Elodea, E. canadensis • Sago pondweed, Potamogeton pectinatus • American pondweed, P. nodosus • Giant pondweed, P. foliosus

  14. Native SAV 06 • Southern Valisineria • American Pondweed • Water stargrass • Elodea

  15. Grow out facility

  16. cages

  17. July 06

  18. Sept 06

  19. Will it survive the drawdown?

  20. Year 2 Get graduate student on board Evaluate success of different plant species in the cages. Replant sites with species that showed the best potential to establish Plant additional TVA approved species that we were not able to acquire this year Actually hydro seed areas

  21. BENEFITS? • Hopefully improved fish habitat which will result in better fishing and better water quality • Even if the plantings fail ALWFF has entered a relationship with angler groups that helps to foster good communication • By getting anglers educated and involved there is less likelihood of them taking matters in there own hands and planting invasives like hydrilla
