18. Habitat Inventory Important Habitat Types in the WGCP Bottomland Hardwoods Moist Soil Wetlands Agricultural Crops Submerged Aquatic Vegetation What are the current management capabilities on Public Lands? Private Lands?

19. Habitat Inventory How much naturally flooded habitat can be expected in a given year? How many acres of open aquatic habitat are available? Ponds (small, medium, large) Lakes Reservoirs Current research? Waterfowl Use of stock ponds Foraging Behavior Food Availability
