2 Where We Work Slide Text Albemarle-Pamlico Peninsula Albemarle Sound Pamlico Sound Atlantic Ocean

3 Wetland Mosaic Landscape Pocosin Swamp forest Pine flat Hardwood flat Riverine swamp forest Estuarine shrub/scrub Fresh marsh Brackish marsh

4 Thick Peat Deposits Peat Depth (ft) Pocosin Swamp forest Pine flat Hardwood flat Riverine swamp forest Estuarine shrub/scrub Fresh marsh Brackish marsh

5 Challenges  Sea-level Rise  1 – 2 ft average elevation  Habitat conversion  Shoreline erosion  Ditched Landscape  > 280 miles of ditches  From timber harvesting and agriculture  Soil oxidation  Salt water intrusion points  Catastrophic Wildfires  Flammable organic soils  2011 Fire: 5.5 million tons C lost

6 Coastal Adaptation Approaches 1.Restore Hydrology (water patterns) a)Water control structures → prevent salt water intrusion b)Ditch plugs → keep ground water levels higher, better oyster growing conditions 2.Construct Oyster Reefs a)Marl and shell bag reefs → reduce shoreline erosion, provide habitat for fish 3.Vegetative Plantings a)Flood- and salt-tolerant species → establish native tree species, eventually adds to peat layer, provides habitat

7 Water Control Structure

8 Upstream Structure

9 Water Control Structure Effectiveness Structure Installed Pains Bay Fire & Hurricane Irene Sound Salinity

10 Oyster Reefs

11 Oyster Reefs and Shoreline Erosion No Reef: 4.2 m/yr Established Reef: 1.7 m/yr

12 Oyster Reefs and Aquatic Faunal Habitat  Oyster Density  Marl: 144 oysters/m 2  Shell Bag: 840 oysters/m 2  Higher species richness along reefs vs. open water

13 Vegetative Plantings  Planting design  40 acres  11,500 bald cypress  2,000 black gum  6,750 pond pine  Planted March 2010  >90% transplant survival  Hurricane Irene 2011  2+ m storm surge

14 Conclusions and Moving Forward  Success with using a mixture of approaches  Natural defenses (oyster reefs)  Infrastructure (water control structures)  Success with willing partners on conservation lands  Improve vegetative planting approach  Evaluate economic benefit of adaptation approaches
