Abstract
ABSTRACT Under federal regulations, natural resource trustees are charged with making the environment whole after injury to or loss of natural resources and services as a result of anthropogenic activities such as waste sites, vessel groundings, or oil spills. Here we provide a case study that uses the Habitat Equivalency Analysis (HEA) model to quantify injury and determine restoration compensation after an oil spill contaminated aquatic resources in the Obed Wild and Scenic River in Morgan County, Tennessee. Our goal is to describe the methodology used for scaling the injury to the restoration activities using the condition of a benthic macroinvertebrate assemblage as the metric. The total injury to stream services was 26.1 discounted service-acre years (DSAYs). The restoration projects chosen to compensate for the injured stream services included streambank restoration (generating 3.68 DSAYs), invasive vegetation removal along 229 meters of stream (generating 0.18 DSAYs), creation of 0.86 ha of bog gar...
