  1. IPM GIS Mapping: A Tale of Rats and Maps NEHA 2014 AEC Convention Las Vegas, Nevada July 10th, 2014 Joshua D. Witt, REHS Environmental Health Program Manager UCLA Office of Environment, Health & Safety

  2. UCLA Founded Students Faculty & Academic Staff Staff Personnel Total Campus Population Acres People/Acre Number of UC Campuses UCLA Population Density 1919 41,341 10,875 31,262 83,478 419 199.2 10 #1

  3. This rodent found a home

  4. Our assumptions • UCLA will always have a baseline population of rodents due to the following factors:

  5. Sections include: Building name Bait station number Location Status/condition Media Pictures Map of station status Bait station analysis

  6. Number of rodent reports 2008: 181 Average 2009-2013: 59.6 Year -67%

  7. What is a bait station? Open Closed

  8. In short: • Where should we reallocate our rodent bait stations and focus our IPM energy to prevent rodent infestations?

  9. Why we want to limit rodent bait stations

  10. What does GIS mean to us? • Our working definition is: Addressing a complex problem using intersecting information to create solutions

  11. Why should we visualize our data?

  12. What are our overarching goals? • Optimize our bait station placement to reduce unnecessary rodenticide • Demonstrate the viability and usefulness of the GIS project to: • Improve campus Integrated Pest Management • Increase stakeholder focus and cooperation • Advocate for situation-appropriate resources

  13. What is GIS? • Visualize • Question • Analyze • Interpret

  14. How did we do it? • Program used: ESRI ArcGIS version 10.1 • To be compatible with UCLA GIS-users • Why is that important? • We need their data and…

  15. UCLA Interactive Map: What Could Be

  16. Which buildings are serviced by EH&S? • 116/265 buildings (~44%) • We do not service medical center or housing business units

  17. Trash Cans • # of trash cans: 616 • Trash cans are not rodent proof

  18. Age of Building • Demarcated by 10 year increments • Shows susceptibility to rodent penetration • Oldest currently existing building built in 1921

  19. Food Facilities • Areas where the campus community consumes food outdoors • 53 locations

  20. Dining Areas 10 dining areas

  21. Rodent Harborage: Algerian Ivy • 11 ivy patches

  22. Loading Docks 35 loading docks 15 are conducive to pests

  23. Vending Machines 49 vending machines

  24. Given all of that… • Where do you think the rodent complaints would be?

  25. Yearly rodent incident reports: 2008-2013

  26. 5 year collection of rodent incident reports: 2008-2013

  27. Bait Stations 269 bait stations

  28. Solution: Suitability Model • A model that weights locations relative to each other based on given criteria • Suitability models might aid in finding a favorable location for a new facility, road, or habitat for a species of bird • Basically, suitability models “put it all together”

  29. Suitability Model: How we weighted our factors • Rodent Report Locations: 30% • Trash Cans: 20% • Building Age: 10% • Food (facilities + dining areas): 10% • Ivy: 10% • Loading Docks: 10% • Vending Machines: 10%

  30. Suitability Model Map

  31. Credits • Credit for project management and creating the GIS maps goes to Alan Chen, MPHand Airalee E. Rivera • Special thanks to Jennie Wung, REHS
