U.S. Forest Service National Insect and Disease Risk Maps

    The National Insect and Disease Risk Maps (NDRM) assess the potential hazard for tree mortality due to major forest insects and diseases across the United States. The NIDRM can summarize landscape-level patterns of potential insect and disease activity. This could help prioritize investment for areas where both hazard is significant and effective treatment can be efficiently implemented. The NIDRM page hosts many up to date supporting documents that describe this project. Numerous Zip files with downloadable GIS raster data (ArcINFO GRID format) and downloadable tabular summaries (MS Excel format) are hosted on the site.

    Cover Crop Chart (version 2.0): Helping producers choose cover crops in crop and forage production systems

      The Cover Crop Chart (v. 2.0) is designed to assist producers with decisions on the use of cover crops in crop and forage production systems. The chart, patterned after the periodic table of elements, includes information on 58 crop species that may be planted individually or in cocktail mixtures. Information on growth cycle, relative water use, plant architecture, seeding depth, forage quality, pollination characteristics, and nutrient cycling are included for most crop species.
