The “RoadsInfo.csv” file provides measures of distance from each wetland site to the nearest road and whether that road was paved or gravel, as this was a part of the study design. Further information may be found in the “Methods.txt” file. Column Information follows: Site---This provides a join field for other information in this dataset. ROADDISTANCE ---This is the measured distance in meters from the water’s edge to the road. RoadType---Describes whether the road was paved or unpaved (gravel). Gravel roads may be coated with dust suppressants or oil for dust control.
