The Kentucky Division of Water, with Eastern Kentucky University and a technical working group, developed a rapid wetland assessment method (i.e. KY-WRAM) to assess wetland quality and aid in establishing mitigation levels and long-term monitoring.

Wetland and amphibian surveys for the 2014 and 2015 seasons were conducted at 42 riverine wetlands in the Kentucky and Salt river basins in Kentucky. Wetlands were chosen from across a gradient of low-, medium-, and high-category scores to compare amphibian communities across a range of wetland condition.

Additionally, species richness was significantly and positively related to KY-WRAM score (p<0.001, R2 = 0.62), and was greater among medium and high category sites than low ones.
