Abstract

Wetlands provide functions such as reducing flooding of surrounding areas and acting as a rest stop for migrating birds. Eufaula National Wildlife Refuge in Alabama has a natural wetland and six artificial wetlands that are differentiated by how they are drained. Remote sensing derived normalized difference vegetation index and normalized difference wetness indexes were used to obtain information about vegetation and wetness at the wetlands from 1984-2011. A correlation analysis was performed to assess the degree of association between vegetation and wetness as a function of management practices. An ANOVA and agglomerative hierarchical clustering were performed to assess the degree of similarity among the different wetlands based on vegetation and wetness. From the results of the correlation analysis, it was found that there is a statistically significant association between vegetation and wetness. The ANOVA and agglomerative hierarchical clustering suggest that wetlands that are managed similarly have a similar association between vegetation and wetness.
