Summary

Coastal wetland ecosystems are expected to migrate landward in response to accelerated sea-level rise. However, due to differences in topography and coastal urbanization extent, estuaries vary in their ability to accommodate wetland migration. The landward movement of wetlands requires suitable conditions, such as a gradual slope and land free of urban development. Urban barriers can constrain migration and result in wetland loss (coastal squeeze). For future-focused conservation planning purposes, there is a pressing need to quantify and compare the potential for wetland landward movement and coastal squeeze. For 41 estuaries in the northern Gulf of Mexico (i.e., the USA gulf coast), we quantified and compared the area available for [...]

Purpose

This effort builds on work by Enwright and others (2015, 2016) which modeled future tidal saline wetland landward migration at the region scale (i.e., all five Gulf coast states). However, there is much potential to use these data for customized analyses focused on landscape conservation design within specific estuaries. The objective of this analysis was to identify differences across estuaries in future landward tidal saline wetland migration opportunities and urban barriers to migration. In broad terms, we provide scientific information that could be used by natural resource managers to enhance the adaptive capacity of coastal wetlands in the face of sea-level rise and coastal development.
