Optimizing Wetland Conservation Programs through Data-Driven Framework

Strategic Insights -

Researchers at the University of Nebraska have developed a data-driven framework to analyze watershed wetness dynamics and prioritize agricultural lands for wetland conservation. By mapping areas with periodic inundation of agricultural lands from 2018 to 2023 and integrating inundation dynamics, soil characteristics, and restoration context, the framework evaluates site suitability for conservation efforts. The analysis identifies approximately 24,000 priority parcels, ranging in size from 0.4 to 20 hectares, for wetland conservation.

Key Takeaways:

  • The research focuses on mapping areas with the most periodic inundation of agricultural lands from 2018 to 2023 using Google Earth Engine and Sentinel-2 imagery.
  • A multi-criteria spatial decision support tool was developed to identify high-priority agricultural parcels for wetland conservation programs.
  • The tool integrates inundation dynamics, soil characteristics, and restoration context to evaluate site suitability for conservation efforts.
  • The analysis ranks watersheds based on the proportion of inundated agricultural lands and identifies priority parcels for wetland conservation.
  • Approximately 24,000 priority parcels, ranging in size from 0.4 to 20 hectares, were identified for wetland conservation.
  • The study recommends prioritizing potential sandhill wetlands in the Sandhills ecoregion, high-potential playa wetlands in the Rainwater Basin area, riverine wetlands along the Missouri, Elkhorn, and Platte Rivers, and saline wetlands in the rural-urban transitional watersheds of eastern Nebraska.
  • The research demonstrates the scalability and cost-effectiveness of remote sensing and multi-criteria geospatial analysis for wetland mapping and site selection.

Statistics:

  • The analysis was conducted on agricultural lands from 2018 to 2023.
  • Approximately 24,000 priority parcels were identified for wetland conservation.
  • Parcel sizes ranged from 0.4 to 20 hectares (1-50 US acres).
  • Priority parcels were identified in the Sandhills ecoregion, Rainwater Basin area, Missouri, Elkhorn, and Platte River watersheds, and rural-urban transitional watersheds of eastern Nebraska.
