Biomass and Biodiversity in Ohio Wetlands: Management Comparisons Over Time.

Wetlands have been increasingly threatened by anthropogenic influences in the modern era. As a mitigation tool, wetlands have been created and restored to provide habitats that harbor ecosystems, as well as perform ecological functions. Humans also benefit from reduced pollution and improved hydrology, among other things. It is important to track comparisons of created and restored wetlands to unplanned sites over time. Four different wetlands were studied for species richness, diversity and biomass. These locations were originally assayed in the summer 2002 and once again in the summer of 2011. In this study, we detected trends on a temporal scale. When considered over time,sites exhibited a decrease in species richness (ANOVA; F1,147 =128.50, P <.0001), but a significant increase in species diversity (F1,147 = 31.87, P <.0001). From these figures, we concluded that agreater level of species evenness accompanied the loss in richness.Furthermore, biomass decreased at most sites for two species: Typha spp.and Scirpus validus. Differences between sites were apparent in some cases. In 2002, there was a significant difference among sites for Scirpus (ANCOVA; F3,18 = 3.33, P = 0.066), but not for Typha ( F3,26= 2.19, P = 0.113). In 2011, there was not a significant difference among sites for Scirpus validus (F3,7 = 3.51, P = 0.1319). However,we did find a significant difference between sites for Typha spp. (F 3,12= 7.12, P = 0.0120).
