Study Will Track Movement of Deer on I-280

In early December, 15 deer will be captured and tagged to track their movements to understand how to keep them from crossing the highway.


The California Highway Patrol (CHP) is informing motorists of a study that will take place in early December that will involve the capture of deer along I-280.

The CalTrans-funded project will be carried out by UC Davis and will study the movement and activity of deer in the area for an 18-month period.

The purpose of the study is to learn how to reduce deer-vehicle collisions along I-280. Upon completion, researchers will submit a recommended action plan to CalTrans.

The California Department of Fish and Game (DFG) will aid UC Davis in capturing deer and fitting them with radio collars to track their movements and better understand how to keep deer from crossing the highway.

Capture dates will be December 2-December 11, 2011. During that time 15 deer will be captured using tranquilizer dart guns and walk-in net traps. The collars will automatically drop off the animals approximately six months later, and another set of 15 deer will be collared.

Due to the nature of the study, the deer captures must be conducted relatively close to the I-280. According to the CHP, motorists may see a DFG vehicle pulled over on the freeway (to check nearby traps) or possibly witness dart gunning in action on a nearby road.

All captures will be conducted from specially marked California Department of Fish and Game vehicles, but at a glance the dart guns may look like rifles and the CHP does not want to alarm motorists.

For more information on the study, contact Clara Laursen or Rose Isarose at 280Connectivity@gmail.com.

I wonder if the Davis folks plan to bring Lt. Pike with them to capture the deer - he will attempt to subdue them with pepper spray no doubt.

Tess - I have links for you... Steve - I just laughed out loud!

TM - Thank you for your thoughts! I really appreciate your input, your mind is going, I love it. "Olfactory repellents" is a good idea, but does need repeat application, I280 is long and exposed to elements, an expense. I hear you about "pointless studies," so you should know, I am a citizen of Santa Clara County, I set out to solve this issue so a) my daughter would never have to experience a large mammal crashing through her windshield b) neither would you and c) the animals on the road broke my heart, and I'm not done until this road has gone through succesful mitigative measures which significantly reduce the likelihood of drivers striking an animal. I didn't get this far because I was a push over who would be content with reading a study after 18 months, neither were those who gave me their time to help get this off the ground. -Reduction of collisions by improving connectivity is the overriding goal- You make an excellent point, I want our results to be transorfmed into action for the betterment of Lifekind, period. As for "Desk jockeys," all I can say to that is we're researchers out in the field, students working towards their degree's and Ph'd's, processing the massive data collected, meeting with public to spur collaboration (I.e. local schools at no cost to them, obviously), etc. Yes, we sit down to work, but not as you've assumed. Lastly, verbal dialogue with deer. For some reason I couldn't get them to learn to speak English (or Spanish), so I spoke for them.

JA - I appreciate your thoughts as well. I can relate in that there are many things I wish my taxes didn't go to. And you speak to the length of the road, it's definately a complex area, thus, our solutions will likely be diverse based on the fact this road is very long, rural and sometimes developed...as I understand it, some local communities are accustomed to living amongst the wildlife. This is why giving the animals appropriate places to get across without risk of injury is key, since we can't just shove 'em to one side. If you'd rather see TE funds go elsewhere, go to the site, check it out. There are 12 different categories, pick up the phone. I can help you get started, just shoot me an email. 280Connectivity@gmail.com Lastly, we are monitoring all species, it mis-speaks when mentioning deer only in the article, they are just the ones getting collars. Thank you for thinking of ALL of the wildlife! I love that. This is a very serious issue of safety, my team is necassary and works (for less than the average secretary) to determine how we can, together, create a safer roadway. Email me directly anytime with questions or venting needs.

This whole study is a joke and a waste of tax payer dollars. Deer cross 280 for feed, water and sex. plain and simple. Use the money to put up deer proof fences if you want to keep the deer off 280 and to keep them from getting hit by cars. The money would be better spent on fences than another study to study another study. Put up the fences.
