Last night's virtual presentation was recorded and they said it would be available in a couple of days here: https://www.youtube.com/c/alaskafishandgame
It was well documented how long it takes sheep numbers to recover after a black swam weather event, but it does concern me how often these events seem to be happening. At what point do we start to manage sheep in a way that factors in such events every 5-10 years instead of the historic 20-30 years? And what does that management look like? I think that's at least a conversation worth having if there is another similar webinar. It's something I think we need to start thinking about and factoring in; and opening lines of discussion on the topic early is a good route to take instead of being forced into rushed decisions later on or not acting until it's too late.
My common sense agrees with you and always has. But I still think sound data needs to give us a concrete answer if our thinking is correct before we can write it off. After last night's presentation, for the first time ever I had a bit of doubt in that line of thinking and I think maybe we do need to look into it more. They made it clear that although the data shows that while most ungulates have nearly a 100% pregnancy rate, the sheep in their studies universally across ranges had significantly lower birth rates (correct me if I'm wrong b/c I had a lot going on last night, but I think I saw years where less than 50% ewes had lambs). Do we have concrete data that shows the reasons for this low rate and that killing only mature rams isn't the reason? Are all ewes getting bred and then miscarrying lambs because of outside environmental stressors? Or are these older sheep more valuable than we thought in making sure these ewes are bred? Maybe they touched on this and I missed it? Maybe there is an actual study somewhere and I missed it? I did have to step away and deal with kids a couple times. Hopefully Joe can maybe touch on something I missed when he sees this post. I know he has very good data based on how full curl and age are recorded on what percentage of legal (mature) sheep are left on the mountain each year. Are those left on the mountain enough?Given that harvesting 8 year old rams has little to no impact on the population and we know that hunters are not killing all of the full curl rams in a given range every year, what management actions should be taken? You can't 'bank' legal rams for the proverbial rainy day and restricting opportunity through drawing hunts will likely do little more than reduce the number of rams that end up on the dinner plate and increase the number of rams that die of natural causes.
View attachment 360960Do you know if this has been recorded anywhere? I just saw this now and realized it happened yesterday haha
There is a big difference between harvesting "60-80% of the rams"...in an area and 60-80% of the rams harvested are by non-residents. I know of no instance where 60-80% of the ram population is being harvested."Watchful Waiting" is not the avenue ADFG needs to go down. I simply can't believe that we still allow nonresident sheep hunters to harvest 60-80% of the rams in 20A & 19C, with the Dept and Board of Game not supporting any limits on nonresident hunters when sheep have been declining for years in those areas.
Just a quick note; there have been quite a few studies of sheep on the Kenai from the early or mid sixties there were some fairly extensive studies conducted. From a regulatory prospective a great deal of attention was given the Kenai starting in the early 1900s. Starting with a series of closures to sheep hunting.Great presentation, I hate to say it but I feel like if they had started studying the kenai mountain sheep before they became so small that now the sample size is insufficient. We would be farther a head then we are now.
That's a bit of a semantic stretch there, Joe, I think most understood what I meant. Anyway, again, really appreciated your historical overview, very well done!There is a big difference between harvesting "60-80% of the rams"...in an area and 60-80% of the rams harvested are by non-residents. I know of no instance where 60-80% of the ram population is being harvested.

If we can assume that killing old rams has no impact on the overall population, then we can all agree that who kills them and how many tags are allocated is a social argument and not a biological one. I still believe that the overall effect on sheep populations by killing only mature rams is negligible. So under this assumption what management actions should be taken? I don't know and I don't really have a suggestion at this point. I would've said more aggressive predator management but after seeing data presented last night maybe that's the solution in the interior, but would likely have little impact in south central. I would simply just like to hear it discussed. I am a biologist/ecologist by profession, so I tend to be on the side where folks tasked with management should be proposing a remedy to us and it's our job to question and scrutinize it to make sure the remedy is sufficient. I think it's time for some "what ifs" or at least the acknowledgement that we may be closing in on a time where we need to do something more.
