Does Tennessee's age data include DMAP and WMA data?

Most of the data is gathered on opening day of rifle season from
a few selected checking stations, from what I understand. I often
wonder how accurate the data is, because many "roaming" 1.5 bucks
are killed on opening day.

After opening day, the check out person at the local 7-11 can't
age a deer. Even with today's technology, the computer check in
system can't tell either.

I have heard the equation before about opening day data, but I
wonder how accurate it is with the.....roaming baby buck factor
on opening day.

Extremely accurate, from start to finish. As expected there are a few mistakes, but some are aged younger and some are aged older. It comes out as a wash.

Setterman,
I wonder why you only quoted a very small portion of my
statement. Whether anyone believes it or not, certain kinds of
data collections, do not tell the whole story. That is true in
other areas too. Not just deer age stats.

I am not a scientist or biologist by any means, but sometimes
"real life", obvious fact, can be detected by a laymen like me.

Ever heard of a political survey that was considered true "data".

You responded to a question about our age data in this state. I was stating that the age data itself is extremely accurate.

I agree, its just hard to beleive 1 weekend of aging at only a few check stations would be enough to properly give an accurate overall prediction!

It happens more then just one weekend here, aging was going on randomly throughout the whole season and there was alot going on during ML and rifle. Just because you don't see a TWRA person at the processor doesn't mean that aging isn't going on at other times.

When we publish our statewide data, only check station data is used. We do collect data from WMAs and check stations but it is not included in our statewide reports (although that may be changing shortly).

RKenney -

You bring up a question many have considered in the past, whether the opening day data collection skews the data. Although I haven't personally looked at our data, other biologists have and what they have all concluded it that there is no significant skew collecting it on the high harvest weekends. If anything, we do see just a few more yearling bucks than what is normally killed throughout the season simply due to the weekend warrior affect. In other words, our true harvested age data if it were collected on every animal would probably be a few percentage points older than what we report.
