Anthropogenic climate change poses a significant threat to Texas' coastal habitats and in the Galveston Bay region, there is just under 1200 square miles of freshwater marsh and undeveloped dry upland. These habitats provide residents with a variety of key ecosystem services but are threatened by global climate change. Effective management of these resources requires multidisciplinary knowledge, combining an understanding of the potential biophysical habitat alterations associated with sea level rise with the measurement of residents' value for coastal resources. In this study, we utilize a discrete choice experiment to investigate individuals' preferences for future conditions of Texas habitats within the Galveston Bay region. Utilizing modeled output for coverage of freshwater marsh and undeveloped dry upland in the year 2050, respondents are asked to make trade-offs between coastal conditions with no further management actions and outcomes associated with specific management interventions. From this framework, we estimate Galveston Bay regional residents' value for freshwater marshes and undeveloped uplands. Our results indicate that individuals are willing to conserve habitat under threat from sea level rise, but that they are likely unaware of the dynamic nature of that change. As a result, residents may place less emphasis on the role of the habitat migration in response to sea level rise.
