2. www.ehs.ucla.edu 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. www.ehs.ucla.edu This rodent found a home

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

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

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

7. What is a bait station? Open Closed

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

9. www.ehs.ucla.edu Why we want to limit rodent bait stations

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

11. www.ehs.ucla.edu Why should we visualize our data?

12. www.ehs.ucla.edu 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. Visualize Question Analyze Interpret What is GIS?

14. www.ehs.ucla.edu 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. www.ehs.ucla.edu Dining Areas 10 dining areas

21. Rodent Harborage: Algerian Ivy 11 ivy patches

22. www.ehs.ucla.edu Loading Docks 35 loading docks 15 are conducive to pests

23. www.ehs.ucla.edu Vending Machines 49 vending machines

24. www.ehs.ucla.edu Given all of that… Where do you think the rodent complaints would be?

25. Yearly rodent incident reports: 2008-2013

26. www.ehs.ucla.edu 5 year collection of rodent incident reports: 2008-2013

27. www.ehs.ucla.edu Bait Stations 269 bait stations

28. www.ehs.ucla.edu 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. www.ehs.ucla.edu Suitability Model: How we weighted our factors 1.Rodent Report Locations: 30% 2.Trash Cans: 20% 3.Building Age: 10% 4.Food (facilities + dining areas): 10% 5.Ivy: 10% 6.Loading Docks: 10% 7.Vending Machines: 10%
