David Burdick presented work a method for estimating the ecosystem services benefits of salt marsh restoration. The approach combines ecological valuation, which uses structural and functional indicators to measure the marshes response to restoration, and economic valuation, which uses ecosystem services valuations, to determine the net gain in ecosystem services of marsh restoration.
