Joe Bonnell, Natural Resources Educator – Natural Resources Institute,
UW-Madison Division of Extension

Evaluating the Relative Contributions of Stream Bank Erosion and Cultivated Field Runoff to P Loadings in the Mill Creek Watershed in NE Iowa County, WI.

Dr. Bonnell is a Natural Resource Educator and the Interim Director of the North Central Region Water Network, Natural Resources Institute at UW-Madison Division of Extension. Dr. Bonnell has been involved in watershed and natural resource management for 30 years. In addition to his Ph.D. in Natural Resources, Dr. Bonnell has a bachelor’s degree in Zoology and a M.S. in Environmental Science from the School of Public and Environmental Affairs from Indiana University. His poster focuses on P loading from stream bank erosion and field runoff in the Mill Creek Watershed.

Jamie Patton, Outreach Specialist – UW-Madison Nutrient and Pest Management Program

Can We Move Past 35%? Increasing Wisconsin’s Cropland Acres Covered by a Nutrient Management Plan

Dr. Patton is an Outreach Specialist for the Nutrient and Pest Management Program at UW-Madison. She provides support to farmers, agronomists, and agency and industry professionals on nutrient and pest management to improve water quality while protecting farm profitability. Dr. Patton’s key programming includes nutrient management in northeast Wisconsin while also assisting with statewide research and outreach on soil heath, soil fertility and cover crops. Her poster focuses on the development of targeted educational initiatives to address the stagnating cropland acres covered by Nutrient Management Plans.

Chelsea Zegler, Ag & Water Quality Outreach Specialist –
UW-Madison Extension

Twenty Years of Discovery Farms Edge of Field Monitoring Indicate Runoff from Frozen and Non-frozen Ground Influence Type of Phosphorus Loss and Effective Agricultural Mitigation Strategies

Chelsea Zegler currently serves as an Agriculture Water Quality Outreach Specialist for UW-Madison Extension. She received a Master’s in Agroecology from UW-Madison, where she focused on forage production and soil health on dairies across the state. Her current work is centered around educating stakeholders on how conservation practices influence phosphorus and nitrogen loss dynamics. Her poster focuses on over 200 site-years of edge-of-field data to better understand the surface water quality impacts of agricultural practices.

Ellen Albright, Postdoctoral Researcher – Center for Limnology, UW-Madison

Internal Phosphorus Loading in Wisconsin Lakes and Reservoirs: Perspectives and Management Considerations from a Global Synthesis

Dr. Albright is a Postdoctoral Researcher at UW-Madison’s Center for Limnology. She is an ecosystem ecologist and biogeochemist studying how inland waters respond to stressors such as nutrient enrichment and climate change. Dr. Albright’s research is inspired by her conviction that everyone deserves access to safe drinking water and that our freshwater resources are a precious gift. Her poster focuses on internal phosphorus loading in Wisconsin lakes and reservoirs as it relates to phosphorus reduction and management.

Laura Bates, Ph.D. Candidate – Nelson Institute for Environmental Studies, UW-Madison

Evaluating the Association Between Biological Indicators and Nutrient Concentrations within the Green Lake Watershed

Laura Bates is a Ph.D. candidate in the Environment and Resources department with The Nelson Institute at UW-Madison. Her research topics include stream ecology, watershed management, water quality, nutrient management, biological indicators, and limnology. Her poster presents a case study on the Green Lake Watershed to assess water quality using biological indicators, highlighting the interconnectedness between local anthropogenic and natural stressors and nutrient pollution affecting this aquatic ecosystem.

Tyler Byrnes, Ph.D. Candidate – Nelson Institute for Environmental Studies, UW-Madison

The Impact of Numeric Phosphorus Criteria on Market-Like Compliance Options

Tyler Byrnes is a Ph.D. candidate in the Environment and Resources department with The Nelson Institute at UW-Madison. His research interests include water quality trading, environmental politics, environmental policy, non-point nutrient pollution, public lands, and science communication. His poster focuses on Wisconsin’s market or market-like policies designed to address excess phosphorus in surface water, providing insight into why regulated entities or producers choose such policies and the hurdles to widespread adoption.
