Erin is interested in the restoration of wetlands. She finished her masters in the summer of 2008 with Dr. Smardon (Environmental Studies) and Dr. Horton (Environmental and Forest Biology) as her co-adivors. She assessed the mycorrhizal status of wetland plants in restored and remnant wetlands in central New York. In addition, she assessing biotic and abiotic factors as indicators of successful wetland restoration.
Erin's MS Abstract:
To evaluate the effectiveness of wetland policy, restored and reference wetlands were compared within the same geographic area. Here I a) compare colonization by arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE) in plants between wetland type and season, b) compare native and non-native plant species richness between wetland type and c), compare soil physiochemical properties between wetland type and season. Data were collected in fall 2005 and summer 2006. There was no difference in colonization by AMF and DSE between wetland types but colonization was higher in the fall when redox was higher. Soil physiochemical properties were more variable in restored wetlands compared to reference wetlands. Restored wetlands had higher plant species richness and evidence of more non-natives. Restoration of wetlands should focus on relationships among soil, hydrology and plants using reference wetland properties as a guide. Better tools for identifying and sampling AMF species should be developed.Return to Horton Homepage
