Napa Valley Historical Ecology Study


Project Overview

Over the past several years, Friends of the Napa River, the Napa County Resource Conservation District, and SFEI have carried out investigations into the historical Napa Valley landscape. This research provides baseline information about local landscape conditions and potential future restoration scenarios on the valley floor. This collaborative effort will culminate in a richly illustrated Atlas, to be published by UC Press in 2012.
