Let’s go on a Field Trip!
4
What is a Wetland? Water (may be seasonal) Impermeable soil Hydrophytic plants
5
Wetland Habitats Pair Up Use Flow Chart to identify ten types of wetlands Use table to mark choices
6
What skills could you teach using this activity? How could you adapt this to meet the needs of your students?

Video on Land Loss Land Loss Video
8
Natural Causes of Wetland Loss Hurricanes Subsidence Wave erosion Sea level rise
9
Process Alterations Made by Humans River levees Large water control structures Construction of Gulf Intracoastal Waterway Ship canal construction Access canal construction
11
Current Funding Streams for Coastal Restoration. Louisiana is working to protect its coastline.
12
CWPPRA Coastal Wetland Planning, Protection and Restoration Act Also know as CWPPRA (pronounced quip-ruh) or Breaux Act Federal Legislation Public Law 101-646 Title III CWPPRA Between $30M and $79M per year Has been funding projects for 20 years Since 1990, it has authorized 148 projects benefiting over 109,000 acres of wetland habitat. www. LACoast.gov

Bayou LaBranche Wetlands – One of the First CWPPRA Projects I-10 Near New Orleans
14
Pass Chaland to Grand Bayou Pass Barrier Shoreline Restoration BA -35 Increasing the barrier shoreline width with dredged sediment.

Mississippi River Sediment Delivery System-Bayou Dupont Before After BA-39
16
Mississippi River Sediment Delivery System-Bayou Dupont BA-39 Pipe jack and bored under the road and railroad to deliver sediment to a marsh receiving area in Plaquemines Parish near the ConocoPhillips plant.
17
Barataria Barrier Island Complex Project: Pelican Island to Pass La Mer to Chaland Pass Restoration BA-35 Installation of sand fencing was concurrent with dune construction.
18
East Timbalier Island Sediment Restoration (TE-25) Almost three million cubic yards of sediment were utilized to establish a 200- foot wide dune and a 600- foot wide marsh along the length of the island. This created 170 acres of intertidal marsh and is helping to protect thousands of acres of existing fringing marsh to the north. To further stabilize the dredged sediments, 13,000 feet of sand fences and approximately 20,000 plugs of marsh grasses were added.
19
Chandeleur Island
20
Big Island Mining (AT-03) Approximately 39,000 linear feet, or over 3 million cubic yards, of dredged material were utilized to create five delta lobes totaling 916 acres of marshlands. An additional 1200 acres are expected to accrete over the 20 year monitoring life of this project.

Coastwide Nutria Control Program (LA-03b)
22
Various Types of Projects… Freshwater / sediment diversion Barrier island restoration / shoreline protection Vegetative planting Hydrologic restoration Beneficial use of dredging material Sediment Trapping
23
State of Louisiana During 2009, the Louisiana State Legislature passed Act 2, which dedicates $290 million in budget surplus monies from fiscal year 2009-10 to coastal protection and restoration. State Master Plan for Coastal Restoration and Protection
24
If nothing is done… Predicted coastal wetland loss in 50 years with no action is 430,000 acres
25
Map of Projected Loss
26
Landloss and Restoration Jenga or Kerplunk Simulation Groups of 3-4 Put together your game. Take turns reading a card. Decide if the action hurts or helps wetlands. Remove a piece from your tower if it hurts wetlands. Skip a turn or add a support piece if it helps wetlands.
