Abstract
Impact of Causeway Construction on Marsh Area Using ArcView Spatial Analyst
Track: Ecology, Archaeology, and Conservation
Author(s): Sandra Fox, Clay Montague
Causeways constructed across the mouths of tidal creeks during the 1920s in northeastern Florida resulted in significant changes in salt marsh creek structure and function and a net loss in marsh area greater than can be attributed to sea level rise alone. In light of interest in causeway removal (potential restoration of the salt marsh), ArcView Spatial Analyst was used to quantify the effects of the causeways on the salt marsh using historical aerial photographs. Calculated yearly rate of marsh loss (marsh converted to creek) was used to predict future marsh area within the study site. Potential impact of causeway removal is addressed.
