These variables determine whether a marsh maintains its elevation with rising sea level or becomes inundated and drowns. Biomass accumulation, above and below ground, and sediment accretion contribute to increases in marsh elevation, while decomposition and sediment erosion result in decreases. The vegetation analyses will help prioritize sites for marsh restoration and aid in developing metrics to measure restoration success.<\/p>\n
Managers also will need to make informed decisions on whether, and where, to encourage wetlands. Our maps will provide information on the areas most vulnerable to erosion and contribute to decisions regarding shoreline stabilization projects, such as the establishment of living shorelines. Study results also may be used in planning for marsh migration corridors into maritime forest swamps and uplands.<\/p>\n
Undergraduates from Chowan University participate in all the project\u2019s field and lab activities.<\/p>\n
Our annual field ecology class was tasked with project setup and initial sampling. Students learned about coastal-barrier ecosystems and processes, climate change, sea-level rise and habitat response, and habitat mapping. They also constructed litterbags for measuring\u00a0decomposition, and PVC quadrats and cores for collecting biomass. Classes in the field mapped wetlands, collected initial biomass samples, deployed litterbags and established feldspar plots for measuring sediment accretion.<\/p>\n
Tyler Richards sorts different species from a vegetation sample as part of his undergraduate capstone project.<\/p><\/div>\n
Three work-study students assist with sample analysis in the lab. Two senior environmental biology students, Charles Blackburn and Tyler Richards, are pursuing undergraduate capstone projects that assume responsibility for part of the overall study. They are examining differences in above- and below-ground biomass between marshes dominated by big cordgrass and common reed.<\/p>\n
Our research project and results will be featured in displays at the reserve and sanctuary starting in summer 2017. These kiosks, located along popular trails, will give an overview of our project, along with background information on climate change and sea-level rise.<\/p>\n
Due to the long timescale of natural processes, our project will not fully answer our fundamental research questions: \u201cCan Currituck Sound wetlands accrete vertically and keep pace with rising seas, and how will wetland areas change?\u201d However, our project will increase understanding in a region where data are limited.<\/p>\n
Moreover, this project has laid a foundation for future collaborations, most likely beginning back where we started \u2014 with seafood and in good company.<\/p>\n
