Since 2006 there have been roughly 10% more licensed hunters than the (1992-2011) average.
And equipment has improved, some areas have better access to hunters, more disposable income etc.
Sheep are under more pressure and although I would like to not accept any of the responsibility and blame predators/lack of burns etc, I think it all adds up.
And anyone in the cattle business knows you don't send yearling bulls out to cover a large herd in tough terrain. I pick up what you are saying Bvw. We need some of those mature rams to keep the sync in the herds.
