What is UCLA>What is the scope of the situation we have to deal with?*Drive home the point that UCLA is NOT just a campus, its a very dense SMALL CITY!!!*UCLA IS A SMALL CITY!!!2This rodent found a home

www.ehs.ucla.eduBecause UCLA is a very dense small city, no surprise it has pests like rodents!3Our assumptionsUCLA will always have a baseline population of rodents due to the following factors:

4Our caveat is that UCLA has and will have a baseline population of rodents due to factors such as overflowing trash bins, significant (though aesthetically-pleasing) ivy growth, and constant construction projects.Bait station analysisSections include:Building nameBait station numberLocationStatus/condition

MediaPicturesMap of station status

www.ehs.ucla.edu5To address these rodent issues, UCLA EH&S uses integrated pest management (IPM), which includes the use of bait stations filled with rodenticide that are provided by our pest contractor.*Do we need a slide explaining what IPM is? Probably.*Maybe we need a picture of an open/closed station

We analyze the performance of these stations using bait station analysis, shown here.Number of rodent reports -67%Average 2009-2013: 59.62008: 181Yearwww.ehs.ucla.eduI think it should say Average 2009-2013. JDW*DONE AC

And through the combined efforts of IPM and bait stations, we have significantly reduced the number of rodent reports. However, we always strive to be better. Thats were something called GIS comes in.6What 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?

8Why we want to limit rodent bait stations

Its not just good for the environment in general. The effects of our use of rodenticide has a face.9What does GIS mean to us?Our working definition is: Addressing a complex problem using intersecting information to create solutions

www.ehs.ucla.eduYou see, we have lots of data. LOTS of data, like hundreds of entries for reports of pests of all sorts. But they exist in either databases or large, cumbersome spreadsheets. We also have accumulated experience with which areas are trouble spots institutional knowledge.

So we have large amounts of data which we use on a daily basis, but to which we dont like at the macro view. And we have large amounts of on-the-ground experience that may or may not be backed up by the numbers.

What if we could visualize the data? It would allow us to take a step back and look at the big picture while also allowing us to check if our instincts are right.10Why should we visualize our data?www.ehs.ucla.eduhttp://www.esri.com/news/arcnews/spring12articles/indonesia-nsdi-one-map-for-the-nation.html

11What 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 ManagementIncrease stakeholder focus and cooperationAdvocate for situation-appropriate resources

www.ehs.ucla.edu\We use GIS to visually present large amounts of complex data that originates from many sources in a simple, easy-to-digest form. Specifically, we will use GIS to optimize our Integrated Pest Management (IPM) program by looking at which areas have been overlooked in our bait station placement, so that we can redistribute appropriately. Broadly speaking, a map of troublesome hot spots will aid us in guiding the combined efforts of various stakeholders to control extant rodent issues, allowing us to advocate for more resources as the situation dictates.

VisualizeQuestionAnalyzeInterpretWhat is GIS?13This is what GIS can look like. Since were in Vegas, were showing this map, created by someone else, that maps the location of Sin Citys famous casinos. GIS maps allow us to visualize, question, analyze and interpret data. In short, it allows us to present large amounts of complex data in a simple format.

http://www.esri.com/what-is-gisGeographic Information Systems (GIS): lets us visualize, question, analyze, interpret, and understand data: to reveal relationships, patterns, and trends.http://www.rexjrowley.com/wp-content/gallery/lvmaps/casinos_streetlabels_title2_legend_nobc_new_nohalo_modified_nolabels.png

It answers questions of EXTREME importance to us visually.

How did we do it?Program used: ESRI ArcGIS version 10.1To be compatible with UCLA GIS-users

Why is that important?We need their data and

www.ehs.ucla.eduThe program we used is ESRI ArcGIS version 10.1. We used this because that is what existing UCLA entities used already in their work. Compatibility with other UCLA entities who already use GIS was a high priority because 1) they have IPM-related data that we needed and

http://s.techtunes.com.bd/tDrive/tuner/rejaur/71471/ArcGIS-Logo.pnghttp://maps.ucla.edu/campus/14UCLA Interactive Map: What Could Be

15Compatibility would allow us, in the long term, to display our data on the UCLA interactive map. As you can see, the interactive map already includes data such as the location of parking lots and bicycle racks. Using this common forum, we could display pest-related data for stakeholders. Although, this is sensitive information, the maps display settings can easily be tweaked to make the information selectively available.

Which buildings are serviced by EH&S?

116/265 buildings (~44%)

We do not service medical center or housing business unitsUCLA has 265 buildings, of which EH&S services 116 (106 if dont count the parking lots. We do not service medical center or housing business units.

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

www.ehs.ucla.eduNow we come to a crossroads. Weve mapped out all the factors, so now we can visualize them and take a look at the entire campus as a whole to take a look at the big picture instead of only being able to see what happens day-to-day. However, this is still limited. How do the factors all fit together? Whats the REALLY big picture? Thats where suitability models come in.

Spend time discussing what I THOUGHT vs. WHAT THIS MAP DISPLAYS
