Wright State University Biology Professor Dr. Stephen Jacquemin and Mercer County Agriculture and Natural Resources Director Theresa Dirksen recently co-authored a study titled “Management of a restored wetland: challenges and lessons associated with the nutrient reduction potential of Beaver Creek Wetland in Grand Lake St. Marys Watershed.”
Key takeaways include:
- The wetland treated about 1.2% of Beaver Creek’s flow over 7 years
- Soluble reactive phosphorus (SRP) was reduced by 78.4%
- Total phosphorus (TP) was reduced by 78.1%
- Nitrate-nitrogen (NO₃‑N) was reduced by 95.7%
- Total suspended solids (TSS) were reduced by 87.5%
From the study:
“Despite these successes, however, GLSM remains hypereutrophic largely resultant of still untreated tributary loading flowing into the lake–thus, this study reinforces the importance of continued wetland restoration and management for meeting overarching nutrient reduction goals.”
