Cover Story: Terrestrial land uses, such as forestry and associated pesticide applications, present cross-ecosystem threats to aquatic species. In Oregon, U.S.A., we deployed passive water samplers and collected riverine and estuarine bivalves from coastal watersheds to examine forestry-specific pesticide contamination. We examined correlations between concentrations and types of pesticide contamination to ownership and management metrics. Pesticides were detected in 38% of bivalve samples, but frequency and maximum concentrations varied by season, species, and watershed with indaziflam (herbicide) the only detected current-use forestry pesticide. We measured four current-use herbicides corresponding to planned herbicide applications; hexazinone and atrazine were most frequently detected. It provides insight into the effectiveness of current forest management practices in controlling transport of forest-use pesticides. View this paper
