Wind Erosion

Working Group

Mission/Vision

Enhance wind erosion monitoring and assessment capabilities through a National Wind Erosion Research Network to support management.

Objectives

  • Support basic research underpinning wind erosion monitoring, modeling, and management across all land use and land cover types.
  • Improve the availability of wind erosion decision-support tools for managers and agencies.
  • Integrate wind erosion analysis tools with farming systems models to support sustainable intensification in US agroecological systems.
  • Facilitate collaboration and integration of monitoring and research programs to increase the impact of wind erosion research for management, planning and policy.

Activities

  • Expand National Wind Erosion Research Network to include new sites in Colorado, Arizona, California, Nevada and Idaho.
  • Develop collaborative research projects linking data and expertise across rangeland and cropland sites.
  • Calibrate and validate physically-based wind erosion model and integrate with the Agricultural Policy / Environmental eXtender (APEX) farming systems model.
  • Produce national wind erosion assessment integrating BLM Assessment, Inventory and Monitoring (AIM) and NRCS National Resources Inventory (NRI) datasets.
  • Evaluate wind erosion responses and feedbacks of business-as-usual and aspirational management strategies across the LTAR network.
  • Develop database system linking wind erosion data and analyses to AIM database, ecological site descriptions in the Ecosystem Dynamics Interpretive Tool (EDIT), National Agricultural Library (NAL) and DataONE.

Accomplishments

  • Established multi-partner National Wind Erosion Research Network in collaboration with the USDA ARS, NRCS, Bureau of Land Management (BLM), US Geological Survey (USGS), Department of Defense and The Nature Conservancy.
  • Published Standard Methods Protocol for Wind Erosion Research and Model Development.
  • Developed website and data portal for the National Wind Erosion Research Network.
  • Installed 10 Network sites across Washington, Idaho, North Dakota, Colorado, Utah, New Mexico, Texas and Oklahoma.
  • Conducted training sessions at Network sites to support quality assurance (QA) and quality control (QC) in data collection, storage and management.
  • Developed physically-based wind erosion model linked to national AIM and NRI datasets
