As far as body condition, i just rated 1-10 as far as what i perceive the animals overall health / condition to be. I think what really matters is location and sex information. That combined with tooth aging gives them the info they want. :dunno:

I wouldn’t put to much into tooth reporting as I think it’s a way to link bear DNA to you in case they find gall bladder or paws on the black market then they can trace It back to possibly a hunter that reported.

I killed a bear a couple years ago and the rug went 6.5ft nose to tail with broken and rotted teeth. Tooth aging came back and it said it was a 1yr old. I don’t believe a bear that 2 men can’t barely move to gut and has a hide of 6.5ft long is 1 yr old.Why would they need to do hair sample gathering tests if teeth would give the dna?

It seems that tooth analysis from the lab in montana is used to age all kinds of animals for nearly all states...

Tooth aging isnt foolproof. For one thing human error is a factor. Teeth can get mixed up etc. Neighbor of mine killed a very large boar and they said it was 2 years old. Also, its not an exact science. Qdma does a lot of collaring / tracking projects on whitetails. I read where they took teeth from several bucks of known ages and sent them in, qnd the results came back anywhere from 1-3 years off in either direction on most of the samples.

Tooth aging in bears is a lot better than for deer as it's based on cementum annuli instead of teeth wear, at least in places w/ strong seasonality (i.e. it works better in Alaska than New Mexico). If bear teeth are in good shape it tends to be accurate at early ages and gets a bit more imprecise at older ages. That said, broken teeth present a problem - they probably just put those in a different category. I wouldn't trust an age from a broken tooth. This is based on data from Pennsylvania where they have known age bears in their harvest
When you send a deers tooth in, cementum annuli is what theyre doing. Same thing as bears.
