Our assumptions
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

Bait station analysis


Number of rodent reports
Number of rodent reports

2008: 181

Average 2009-2013: 59.6

-67%



In short
In short:

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



What does gis mean to us
What does GIS mean to us?

  • Our working definition is: Addressing a complex problem using intersecting information to create solutions



What are our overarching goals
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


What is gis
What is GIS?

  • Visualize

  • Question

  • Analyze

  • Interpret


How did we do it
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…



Which buildings are serviced by eh s
Which buildings are serviced by EH&S?

  • 116/265 buildings (~44%)

  • We do not service medical center or housing business units


Trash cans
Trash Cans

  • # of trash cans: 616

  • Trash cans are not rodent proof


Age of building
Age of Building

  • Demarcated by 10 year increments

  • Shows susceptibility to rodent penetration

  • Oldest currently existing building built in 1921


Food facilities
Food Facilities

  • Areas where the campus community consumes food outdoors

  • 53 locations


Dining areas

are conducive to pests


Vending machines

Given all of that
Given all of that…

  • Where do you think the rodent complaints would be?



5 year collection of rodent incident reports: 2008-2013


Bait s tations
Bait Stations

269

bait stations


Solution suitability model
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
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%
