Research

  • Invasive plant ecology
  • Invasive plant detection, with emphasis on remote sensing, identifying areas likely invaded for early detection and rapid response survey
  • Integrated pest management of weeds in hay, pasture CRP and wildland areas
  • Plant community rehabilitation, with special attention to both invasive plant interactions and soil interactions
  • Modeling plant movement across landscapes
Extension
  • Administer the Lambert Erickson Weed Diagnostic Laboratory that identifies, tracks and surveys for invasive plant species
  • Provide technical and educational program support to Cooperative Weed Management Areas in Idaho
  • Collaborate with county faculty on pasture and wildland projects
