  1. Black Bear Damages in Virginia

  2. Executive Summary • Analyze incidents of damage performed by black bears based upon county of incidence and type of occurrence. • POTENTIAL SOLUTIONS: • providing more resources for counties that are shown to have an increased likelihood for bear damage and conflict • changes in land use and zoning for those counties with a higher incident rate.

  3. Goals • Determine which Virginia counties have the most incidents of black bear damage and sightings, as well as the various types • Obtain an accurate portrayal of black bear confrontations within Virginia

  4. Objectives • Create map of Virginia counties • Convert data from raw data into .dbf table • Join data to county shapefile and analyze

  5. Data • County shapefile • VDGIF raw data for 2006-2007 • PROBLEMS • scattered reporting • 2 different codes used on forms

  6. Virginia Counties with Black Bear Damage Incidents

  7. Public Safety Concerns

  8. Trash Disturbances

  9. Property Damage

  10. Birdfeeder Damage

  11. Crop Damage

  12. Livestock Damage

  13. Livestock Feed Damage

  14. Other Damage

  15. Multiple Incidents

  16. Black Bear Sightings with no Damage

  17. Relocation

  18. Kill Permits Issued

  19. Analysis • Simple chloropleth maps • Import data as .dbf table • Join damage info with VDGIF county table • Join combined tables to county shapefile

  20. Analysis 2 • Create new layers for various types of incidents • Select by attribute for each element and export selected features • Convert each new layer into individual chloropleth map based on number of incidents

  21. Conclusions – Recommended Solution • Stringent monitoring and increased resources for counties with significant damage incidents • Include educational materials and trained personnel

  22. Conclusions - Counties • SIGNIFICANT ACTIVITY • Albemarle – 233 incidents • Tazewell – 61 incidents • Campbell – 42 incidents • LOWER ACTIVITY • Clarke, Page, Madison, Lancaster, Bath, Giles, Pulaski, Wythe, Carroll, Grayson, Buchanan, Wise, and Lee

  23. Conclusion - Problems • Problems importing tables • Geodatabase would not work • Editing tools would not work • Data problems - confusing

  24. Conclusion - Changes • More detailed map – topology • Include surrounding cities

  25. Future Suggestions • Compare county population vs. number of incidents • Potential population growth • Types of land use – i.e. farming vs. urban • Pinpoint more precise location within counties for each incident • Use more years in data
