  2. 2. Update on the ACPF JULY 31, 2019 SWCS ANNUAL CONFERENCE, PITTSBURGH 1. Watershed Applications of the ACPF for Stakeholder Engagement, Research, and Modeling – Ann Lewandowski, University of Minnesota Water Resources Center 2. ACPF Version 3: Riparian Watersheds with Applications for Landscape Analyses – Mark Tomer, USDA ARS 3. Expanding Access: ACPF Website and Training Resources – Anne Nardi, University of Madison- Wisconsin Extension 4. Farmer Engagement Using Precision Approach to Conservation Planning: What Do We Know? – Pranay Ranjan, Purdue University 5. A Tool to Evaluate Economic Opportunities and Tradeoffs Using the ACPF – Emily Zimmerman and John Tyndall, Iowa State University 6.

  3. 3. Watershed Applications of the ACPF for Stakeholder Engagement, Research, and Modeling ANN LEWANDOWSKI, UNIVERSITY OF MINNESOTA WATER RESOURCES CENTER
  4. 4. The ACPF is. . . 1. A unifying concept for water quality management in agricultural watersheds (conservation pyramid). 2. Input data consistent across watersheds and regions. 3. ArcGIS toolbox identifies a full menu of possible locations for conservation practice installations. HUC-12 is intended unit of analysis. Facilitates landowner involvement in planning by providing choices for conservation practice implementation with spatial precision.
  5. 5. ACPF Concept: Conservation Pyramid for Agricultural Watersheds (Tomer et al., 2013)
  6. 6. ArcGIS Toolbox Identifies a menu of possible locations for conservation practices One tool for each practice User options are built in. ◦ Results will be optimized with experience and with local knowledge of the watersheds
  7. 7. ACPF Toolbox DEM Hydroconditioning Flow network definition Field characterization ◦ By-field slope statistics ◦ Tile drainage determination ◦ Distance to stream ◦ Runoff risk assessment Terrain derivatives (SPI, TWI) Opportunities for practices ◦ Depressions and their drainage area ◦ Drainage water management ◦ Grassed waterways (SPI) ◦ Contour buffer strips ◦ Bioreactors ◦ Nutrient removal wetlands ◦ WASCOBs ◦ Sat’d buffers Riparian function assessment
  8. 8. Input databases Databases developed specifically for agricultural conservation. Also used for the Daily Erosion Project. Consistent across the region High enough resolution to analyze terrain at the field level
  9. 9. Input databases Field boundaries Land use ◦ Past 6 years, based on Cropland Data Layer USDA/NRCS Soil Survey data (gSSURGO), 10m grid High resolution elevation data ◦ Hydro-modified by user (tools included in the ACPF toolbox) ◦ Critical for all practices to identify water flow
  10. 10. ACPF Requirements Expertise ◦ Moderate proficiency in ArcGIS ◦ Knowledge of the local landscape and practices. Time ◦ 2 days - technical training for an experienced GIS specialist ◦ 2 days - hydro-modify a HUC12, and define flow networks ◦ ½ day - run the practice siting tools on one HUC12 ◦ ? - Verify output and develop display maps Software ◦ ArcGIS Advanced version, with Spatial Analyst extension ◦ TauDEM (free)
  11. 11. Application examples Justify proposals Facilitate engagement Inform implementation Make farm visits more effective Inform state nutrient reduction strategy
  12. 12. Application examples Justify proposals Facilitate engagement Inform implementation Make farm visits more effective Inform state nutrient reduction strategy ◦ HeartLands Conservancy used ACPF as part of planning in the Upper Silver Creek watershed (southwest IL) using an EPA 604b watershed-based planning grant. ◦ Identified areas of highest priority for nutrient removal wetlands. ◦ ACPF helped them quantify realistic potential, and estimate potential impact.
  13. 13. Application examples Justify proposals Facilitate engagement Inform implementation Make farm visits more effective Inform state nutrient reduction strategy ◦ Wilson and Annis Creek Watershed Partnership (WI) set priorities and goals for agency implementation. ◦ County conservation staff provided ACPF maps of conservation opportunities so the watershed group could discuss priorities and what they were willing to do.
  14. 14. Application examples Justify proposals Facilitate engagement Inform implementation Make farm visits more effective Inform state nutrient reduction strategy Iowa Soybean Association used ACPF to identify practice locations after landowners had identified priority issues and practices, and modeling had quantified the number of practices needed.
  15. 15. Application examples Justify proposals Facilitate engagement Inform implementation Make farm visits more effective Inform state nutrient reduction strategy Root River (MN) Fields to Streams Partnership used ACPF analyses to prepare for farm visits.
  16. 16. Application examples Justify proposals Facilitate engagement Inform implementation Make farm visits more effective Inform state nutrient reduction strategy State contracted ISU’s GIS lab to map potential saturated buffer sites statewide and nutrient removal wetland sites
  17. 17. Application examples Justify proposals Facilitate engagement Inform implementation Make farm visits more effective Inform state nutrient reduction strategy Who sees the maps? When in the planning and implementation process? With what other tools?
  18. 18. Example research questions • Edge of field monitoring results: What is the extent of field settings similar to a monitored location? • Regional planning: How does the extent of locations suited to a specific practice vary among watersheds and landform regions? Can this information help better budget conservation expenditures and prioritize research/demonstration efforts? • Stacked practices: What is the most prevalent opportunity to combine in-field and edge-of-field practices? • Social engagement: How can the availability of detailed information on conservation practice siting opportunities in a watershed best be leveraged to engage landowners to participate in watershed improvement?
