The Monarch Butterfly Wildlife Habitat Evaluation Guide (WHEG) and Decision Support Tool: Midwest Region is used by NRCS staffs as a planning tool to evaluate current habitat conditions at the assessment area scale, not at the farm or ranch scale. Following the assessment, a rating is assigned to each assessment area within the farm or ranch.
