Estimating Long-term Phosphorus Retention Capacity of Ohio Riverine and Coastal Wetlands

Date and Time: 
Wed, 03/11/2020 - 3:30pm to 4:30pm
Kristi Arend, Emily Kuzmick, and Song Qian

Just how much phosphorus can a wetland absorb and retain over the long run? That’s the question that researchers have spent the past two years investigating as part of an effort to reduce the phosphorus loading that is fueling algal blooms in Lake Erie. A research team from Old Woman Creek Reserve and the University of Toledo developed a Bayesian hierarchical modeling approach to calculate the phosphorus retention capacity of wetlands with limited datasets. 

In this webinar, the team will share some of their key findings, management implications, and potential for other practitioners to use their monitoring guide and statistical codes to calculate the nutrient retention capacity of their wetlands. In addition to taking audience questions, the team will offer some ideas about how their work informs an ambitious new water quality initiative in Ohio.

Cressman Cumulative Change

Kristi Arend is the Research Coordinator at Old Woman Creek NERR, where she has overseen the implementation and onsite expansion of the System-side Monitoring Program and has collaborated on projects related to wetland nutrient dynamics, shoreline development, and the impacts of Lake Erie water level change on wetland ecosystem indicators. Her research interests include how physicochemical conditions and linkages between ecosystems influence coastal water quality, fish communities, and food web dynamics. Kristi also enjoys opportunities to help OWC NERR’s education program provide students hands-on experiences in aquatic ecology, especially if fish and bugs are involved.

Emily Kuzmick is the Coastal Training Program Coordinator at the Old Woman Creek National Estuarine Research Reserve, where she works with environmental professionals to provide training and technical assistance relating to stormwater and nutrient management, land-use practices, species and habitat monitoring, shoreline erosion control solutions, and other identified Great Lakes coastal issues. Emily’s past research efforts focused on how anthropogenic activities impact the natural environment, including the effect of marine debris and conventional agricultural and renewable energy activities on wildlife populations. Her additional experience in environmental education, advocacy, and as a contributor to sustainability publications has enhanced her ability to communicate complex environmental issues.

His research includes several papers quantifying an Everglades wetland’s assimilative capacity of phosphorus and setting ecological threshold nutrient criteria in the U.S. As part of the project, Dr. Qian led the statistical analyses of wetland datasets, assisted in creating the monitoring guidelines and protocol, and recruited and supervised students.
