From the waaaaaayback machine! Did Bruce start this thread when he was a kid? ;)
I was reading this and also thought that 1.5 million deer collisions seems high. But there wasn't an internet when this thread started and now there is, so here's some more data.
There's actually a wiki on this and it claims 1 million animal-vehicle collisions and 200 deaths annually.
http://en.wikipedia.org/wiki/Deer%E2%80 ... collisions
The "Insurance Journal" says it was an
estimated 1.23 million in 2011.
USAToday has a piece that shows what the most dangerous states are (PA, WV, MI, IA, SD) and how late autumn and early winter are exponentially worse due to mating seasons.

And it all seems a little high to me anyway.

These numbers are established by insurance companies. But people aren't always honest. I know of three people personally who were involved in distracted driving accidents that reported animal involvement as the cause. (For the record, it doesn't matter to the insurance company. Unless another person/driver causes the accident, it's your fault whether you were changing the radio station, texting, or a deer ran into the road). Point is, I think the insurance numbers might be inflated.
I found a report from Washington State that covered a 5-year period (2000-2004) and used only data from deer and elk carcasses removed from state roadways.
14,969 deer, and 415 elk carcasses were removed from state roadways over those 5 years. Thats about 3,000/year or about 10% of the math Joe did above ... 8 deer per day. It is interesting to note that only one elk carcass was recovered every 5 days on average over those 5 years. The Washington State study emphasizes that it only covers carcasses recovered, and that animals struck who traveled beyond the roadway and died later are not counted, nor are those on city-owned roadways. It mentions a study that estimates an additional 5x more deer were probably killed by vehicles than those whose carcasses were recovered on or adjacent to the roadway. Even so, the math still adds up to about half of the estimates reported elsewhere.
It's worth noting that elk are substantially larger than deer, and may have higher survivability rates after a vehicle collision. Or at least the ability to get farther from the roadway before expiring, therefore not being counted as highly in the Washington State study.

Reports from Wisconsin showed over 25,000 deer removed from roadways by either state highway contractors, or via free hunting tag (mmm road kill!). That's 68/day, and you'd have to figure that more are hit that don't die. This might be the closest figure to the estimate I can find. But it's difficult to extrapolate data from a state like Wisconsin to other states with much smaller deer populations.
In Arizona, AZGFD reports that about 75% of vehicle animal collisions on I-40 from Williams to Winona, I-17 from Flagstaff to Stoneman Lake, and AZ-260 from Payson to Forest Lakes are due to elk. If you travel the 260 east of Payson, you may have seen the elk crossing areas that have been installed in the past decade or so.
An AZGFD study I found showed that prior to the elk crossings, an average of 12 elk were struck by vehicles in a 3-mile study area at Preacher Canyon. If you extrapolate the data to cover the 30 miles from Payson to the top of the rim, that would be 120 elk struck annually on just that segment of AZ-260. Which is about one every three days. With about 2.5 million cars passing through there annually, the odds were about 1:20,000 of you hitting an elk when you drove that stretch.
Now that the elk crossings have been installed, the rate of collisions has dropped by over 90% according to the AZGFD report (commissioned by ADOT).
In the end, data can be made to tell whatever story the entity seeking funding wants it to tell. Which usually isn't true.
So that's all I feel like reading on this topic tonight. Interesting stuff though!
