[2] Plants and soils in wetlands have a very active and significant role in the environment because they filter water by removing high levels of nitrogen and phosphorus.

[2] The Black Lake Terracing Project is led by Ducks Unlimited and includes 16 partnerships from other states, federal, nonprofit, and private partners.
[2] Black Lake Terracing Project focuses on areas that contain migration and wintering habitats for scaup, mottled duck, northern pintails, and mallards.
[3] In Morgan Brake's wildlife, NAWCA has converted empty crawfish ponds to moist soil units.
[3] In order to convert the ponds to soil units, wells and underground irrigation must be improved along with redesigning levees that are in the area.
[3] By enhancing levees and building new and better ones will allow refuge staff to better control flooding of moist soil plants and agricultural crops for waterfowl.
