The timeframe of the use of neonic’s makes sense in species decline.
Do they not use neonicotinoids in the northern states where turkeys are numerous?
Yes, we use neonicotinoids up here. Lots of people trying to outlaw them and typically use the honey bee for emotional support/backing. I don't see it having merit as I run about 70 hives next to farmlands that neonics are used. I know of a guy who runs 1500 hives in Manitoba on his Canola farm. He has a success rate that most of us would die for and uses plenty of Neonics right next to his hives...and it's not hard to kill bees.
Now I can see someone making an argument along the lines of "application differences" from state to state? ( If there's any difference). I'm not aware of any differences in application mandates....but I wouldn't be a person who would know, in reality.
Here in MN. (According to the DNR) we have not seen much of a decline in turkey numbers, other than sporadic talk...actually a steady growth of both turkey and hunters, according to the DNR.
Most of the turkeys in this state are located in the Southeast region where farmlands is present amongst mature trees/hills, etc. Last year we harvested a little over 12,000 turkeys in the spring season alone with more hunters than ever before. The DNR claims hunting has no effect on the numbers.
MN (at least where most of the turkey are) also have plenty of predators: Coon, skunk and of course coyotes galore.
When MN introduced Turkeys decades ago, I remember having some real hard winters. They didn't die off but continued to grow and expand their ranges
I don't pretend have any answers...and why I posed the initial question. Thanks for the comments. I find them interesting (in a good way).
