Wisconsin | There was a "study" out of UW Madison I believe, that claimed wolves caused a significant drop in car deer accidents. Plenty in the study to disagree with, they didn't collect any data, just analyzed numbers, but I agree with the conclusion. Wolves have a MUCH bigger affect on deer than the ones they kill, whether that's a lot or not that many killed directly. In the car example, wolves travel roads and deer learn to avoid roads and hang out in deeper cover.
For population, just compare a goat to a cow, a productive goat will have twins around it's first birthday, a cow will have a single at about two years old. Deer fawns used to regularly carry twins their first year, I'd bet areas with wolf pressure are going to have more and more two year old does having a single for first birth, that is HUGE for the population. | |
