Variable General Info

Name variable.detail.varNameHelp ?	Natural log of wetland size ? Comment: For each of 27 separate wetland sites of varying size, GIS-based land cover developed from 2002 Landsat imagery was used to classify land cover. Polygon coverages of the CREP wetlands and buffers were aquired from the Iowa Department of Agriculture and Land Stewardship (2007) and added to the 2002 land cover.	Waterfowl species ? Comment: Six species of ducks were modeled; Mallard (Anas platyrhynchos), Blue-winged Teal (Anas discors), Northern Shoveler (Anas clypeata), Gadwall (Anas strepera), Northern Pintail (Anas acuta), and Wood Duck (Aix sponsa). Species is a class variable forming the basis for six model runs.	Mathematical constant (waterfowl pairs)	Proportion of basin containing water ? Comment: All CREP wetlands were considered to be semi-permanent for this analysis.	Species specific alpha value	Species specific regression coefficient a	Species specific regression coefficient b	Waterfowl pairs ? Comment: 27 separate, individual CREP wetland sites
