These data were complied for the primary analysis underlying the results presented in the manuscript associated with these data (see Larger Work Citation). The data was collected from a 2015 survey of private party Grand Canyon boaters. The open document file contains 3 data sheets: 1) variables used in the Table 2 comparison of samples, 2) the core dichotomous choice contingent valuation questions and responses (used in Table 3), and 3) The Discrete Choice question data used for the models estimated in Table 4.

Predicting Climate Change Impacts on River Ecosystems and Salmonids across the Pacific Northwest
Salmonids, a group of coldwater adapted fishes of enormous ecological and socio-economic value, historically inhabited a variety of freshwater habitats throughout the Pacific Northwest (PNW). Over the past century, however, populations have dramatically declined due to habitat loss, overharvest, and invasive species. Consequently, many populations are listed as threatened or endangered under the U.S. Endangered Species Act. Complicating these stressors is global warming and associated climate change. Overall, aquatic ecosystems across the PNW are predicted to experience increasingly earlier snowmelt in the spring, reduced late spring and summer flows, increased winter flooding, warmer and drier summers, increased...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
