The Effect of Long-Term Marsh Management on Land-Loss Rates in Coastal Louisiana

3 ha) studied previously were obtained, expanded, and tested statistically to provide empirically valid conclusions over a longer management period than previously available (1–32 years compared to 6–37 years). There was no statistically significant difference between managed and nearby reference sites. The effects of changes in the regional environment appear to have had much greater influence on the land-loss rates than did management at individual sites.
