The Wisconsin Buffer Initiative pilot project on the Pecatonica River is a collaboration among academic, county, state, federal and nonprofit partners. Here’s what a few of them have to say about their role in the partnership.
Director of Conservation, Agricultural Landscapes
The Nature Conservancy
How are corporations and foundations like The Monsanto Company and the McKnight Foundation supporting this project?
Steve Richter: With financial support from The Monsanto Company, the McKnight Foundation, and other individuals, corporations and foundations, the Conservancy is providing resources to this project that help fund monitoring, staff time for landowner outreach and financial incentives for landowners. Support from private sources allows us to reduce the risk for landowners to try new management practices, which often cannot be funded through public dollars. These private donations have been used to secure additional public funding for the project from the U.S. Department of Agriculture.
USDA-Natural Resources Conservation Service
How is the Natural Resources Conservation Service supporting this project?
Adam Dowling: The Dane County Land and Water Resources Department submitted a Cooperative Conservation Partnership Initiative (CCPI) grant proposal to the Natural Resources Conservation Service (NRCS) requesting financial assistance for landowners willing to enter into agreements to address phosphorus losses from farming operations in the Pleasant Valley Watershed in southwestern Dane County. CCPI is a voluntary conservation initiative that enables conservation programs such as the Environmental Quality Incentive Program (EQIP) and Wildlife Habitat Incentive Program (WHIP) to landowners. Twenty-two operators entered into contract agreements to implement practices such as streambank protection, stream habitat improvement, nutrient management, no-till and barnyard runoff structures. To date, $621,000 has been allocated to the 22 farm operators.
NRCS staff provides oversight for the contract agreements over the next three to four years. Additionally, NRCS will assist partners in evaluating the effectiveness of the practices applied and encourage landowners to implement additional conservation activities that will result in a holistic resource management system addressing all resource concerns.

How is the Soil Science Department at the University of Wisconsin-Madison contributing its science expertise to this project?
Laura Ward Good: This project is testing whether we can identify and change management on the fields contributing the most phosphorus and sediment to the stream and, consequently, get real improvements in stream water quality. The assessment we are using to rank fields by their runoff phosphorus contributions is called the Wisconsin Phosphorus (P) Index and it, along with field erosion rates, is calculated in a software program called SNAP-Plus. The P Index and SNAP-Plus were developed by the UW-Madison Soil Science Department. In this project, we are using the P Index both for targeting high contributing fields and for assessing the effects of management changes on runoff phosphorus losses. Working with our project partners in the Biological Systems Engineering Department and at the U.S. Geological Survey, we are trying to develop easy-to-use assessment models for determining how reductions in phosphorus and sediment leaving fields will affect watershed outputs. These models will help determine how much and what types of management changes need to take place at the field scale to achieve watershed water quality goals.
Curt Diehl, Pat Sutter and Duane Wagner
Dane County Department of Land and Water Resources
What is the county’s role with landowners in this project?
Pat Sutter, County Conservationist: We have been working closely with landowners on a handful of farm fields in the watershed that are contributing the majority of the nutrients and sediment to the stream. We met with the landowners about their farm practices and developed and put into place recommendations for how they might do things differently to reduce nutrient and sediment loss into streams. For example, some decided to switch some of their fields from a more intensive tillage system where most of the crop residue from the previous year is removed to no-till where seeds are planted directly into the residue remaining from last year’s crop. Less soil disturbance means less chance of soil and nutrients washing into streams when it rains. We are also keeping track of changes in land use that take place. For example, lands once in the Conservation Reserve Program are now being planted to row crops of corn and soybeans. Our staff will meet with the operators to make sure they are following a conservation plan to minimize nutrient runoff.

How are you working with landowners to analyze the economic impacts of proposed management changes?
Jim Leverich: We're visiting farms in the pilot area helping landowners implement practices that have the greatest potential to reduce the contribution of nutrients to streams and improve farm profitability. We talk about their crop rotations, planting techniques, how they handle manure and other management practices to identify best management practices (BMPs) that can improve environmental and economic performance. Together we do a financial inventory of the costs associated with the different enterprise parts of their farm operations like dairy, hay and corn. We want to see how the management alternatives we’re proposing will impact their bottom line. Our goal is to choose those alternatives that will help reduce nutrient and soil losses and work well with their current farm operations to improve their profitability.
Becky Carvin and Dr. Faith Fitzpatrick
Physical Scientist and Research Hydrologist
U.S. Geological Survey
How is the U.S. Geological Survey involved in monitoring the results of the project?
Becky Carvin: We are measuring stream flow and precipitation and collecting water samples to be analyzed for suspended sediment and total and dissolved phosphorus in the two sub-watersheds that are part of this pilot project—the one where we will be working with farmers to make management changes (test watershed) and the other where no action will be taken (control watershed). We started collecting data in 2007 so we could get two years of baseline data before any management practices were changed. We are collecting data as the changes are being made, and we hope to continue monitoring for a number of years after that. We want to be able to compare our data for both watersheds to see if there are any statistically significant differences in water quality between the test watershed and the control.
Faith Fitzpatrick: In addition to daily stream monitoring, we are surveying both watersheds and developing a sediment budget for each as a way to track sediment and nutrients from the fields through the watershed to the outlet. This information will help us better understand the delay between when farming practices are changed and when those improvements are seen in water quality. Over time, these monitoring efforts should tell us whether or not the changes farmers are making are having a positive impact on water quality.
Jim Amrhein, Bob Hansis (retired) and Greg Searle
Wisconsin Department of Natural Resources
How is the Wisconsin Department of Natural Resources involved in monitoring the results of the project?
Greg Searle, Section Chief, Monitoring and Management: We are monitoring the streams in both the test and control watersheds for the fish assemblage, habitat assessment and invertebrates. Determining what species of fish are in the stream and their abundance is our best indicator of stream health because we have a robust set of fish data across the state of Wisconsin. The results of this monitoring enable us to show how the stream compares with other streams in the region and to evaluate the impacts of the targeted conservation practices put into place in the test watershed.
Anita Thompson, John Panuska and Jasmeet Lamba
UW-Madison Biological Systems Engineering
How is UW-Madison Biological Systems Engineering contributing its science expertise to this project?
Jasmeet Lamba: We are estimating the relative proportion of in-stream sediments and sediment-bound phosphorus coming from different sources in the watershed that travels downstream and is recorded at the USGS water quality gage. Some of the sediment and phosphorus is entering the stream in runoff from farm fields; in other cases, where land use is dominated by woodlands and grasslands, it is coming from the streambed and banks. The more cropland there is in a watershed, the greater the contribution of in-stream sediments from farm fields. Also, knowing the role that the streambed and banks play in storing or releasing phosphorus will help us determine the lag time required before we can expect to see an improvement in water quality in the test watershed.
