This rodent found a home

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

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

Number of rodent reports -67% Average : : 181 Year

What is a bait station? Open Closed

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

Why we want to limit rodent bait stations

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

Why should we visualize our data?

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

Visualize Question Analyze Interpret What is GIS?

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…

UCLA Interactive Map: What Could Be

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

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

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

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

Dining Areas 10 dining areas

Rodent Harborage: Algerian Ivy 11 ivy patches

Loading Docks 35 loading docks 15 are conducive to pests

Vending Machines 49 vending machines

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

Yearly rodent incident reports:

5 year collection of rodent incident reports:

Bait Stations 269 bait stations

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”

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%
