Project Description

Learn how restoration ecologists have helped Don Edwards Refuge maximize the amount of soil it obtains to build habitat and levees while ensuring that soil has low contaminant levels so wildlife and wetlands are protected. Gavin Archbald of H. T. Harvey & Associates discusses his work implementing and refining the regulator-required Refuge plan for sampling soil pollutants and managing which soils are clean enough to place onsite. Archbald provides an overview of this plan, called the Quality Assurance Project Plan for the Don Edwards National Wildlife Refuge or QAPP, how it is implemented, and how the document has been refined over the past 6 years to provide greater flexibility to import soil needed for restoration while remaining protective of aquatic habitats.
