SGA

    Stored Grain Advisor (SGA) is a decision support system for managing insect pests of farm-stored wheat. The program predicts the likelihood of insect infestation, and recommends appropriate preventative actions . It also provides advice on how to sample and identify insect pests of stored wheat. SGA Pro was designed for use in commercial elevators as part of the Areawide IPM Project for stored grain. Grain samples are taken with a vacuum probe and processed over an inclined sieve. SGA Pro analyzes the insect data, grain temperatures and moistures, and determines which bins need to be fumigated.

    Varroa Pop

      Varroa Pop simulates the growth of Varroa mite population in honey bee colonies. The program demonstratres how Varroa mites influence colony population growth throughout the year. You can change many factors through the menus in the model such as the initial population size, queen egg laying potential, and mite reproduction rates, so you can see how these factors influence both colony and mite population growth. We hope that the model will help you understand the interactions between the honey bee and mite populations and provide insights on how best to control Varroa in colonies.

      Arctic Peregrine Falcon Abundance on Cliffs Along the Colville River, Alaska, 1981-2002 and Covariate Input Files

        This data set consists of fourteen data files. Rcode_arctic_peregrine_abundance.R contains R code that was used to analyze Arctic peregrine falcon data collected between 1981 and 2002. The code primarily uses the R package "UNMARKED" and is based on the Dail-Madsen model for estimating population abundance. To run this code in an R environment, download the file and open it in an R interpreter (such as RStudio). The remaining files are all covariate matrices that act as inputs to the R code.

        NRCS Regional Conservation Partnership Program - Columbia River Basin

          The Columbia River Basin provides habitat for salmon and steelhead, essential components of a healthy ecosystem and critical to Indian tribes and local communities. Loss of quality habitat because of pressures from population growth threaten fish numbers and the overall health of the basin. With this Critical Conservation Area designation, USDA will build on existing strong partnerships in the basin to work with agricultural producers to improve water quality and quantity in order to restore critical components of salmon habitat, aid in the recovery of Pacific salmon, and protect public health and the environment while maintaining a strong agricultural sector. The boundary of the CCA is a portion of the Columbia River Basin that includes essential fish habitat. This dataset includes a printer-friendly CCA map and shapefiles for GIS.

          National Plant Germplasm System

            The U.S. National Plant Germplasm System (NPGS) is collaborative effort to safeguard the genetic diversity of agriculturally important plants.
