From what I've heard so far numbers are a bit lower, I haven't heard the unofficial count yet, it takes a month or so to get the preliminary numbers. I'd say maybe 10-15% lower at most. The winter was rough in some areas, but what we saw this year was more a factor of the winter of 2012 which killed most all the lambs and a lot of the yearlings in many areas. Next year will be pretty rough in many areas too. The good news is 2 years out we'll see the bumper crop of lambs (rams) start to crop up into the bag. Bad news is we'll experience the same as this year 7-8 years from now, and the ewes took a beating last winter in many areas.
The long term weather forecast is an easy winter. The summer was wetter than normal, and there was lots of feed for them going into fall/winter. Unless we get a bad winter, I would expect a good lamb crop this spring.
Mature rams fair much better than ewes do in bad winters, although some of the older rams don't make it. Its kind of a double whammy. Not enough old rams to fill the void of the rams that are missing in the fall to harvest.
On a given year about 15-20% of rams killed are 7 year olds, 45% are 8yo, 25% are 9yo, with the rest being older and a few younger. Since there is a "hole" in the age class where the majority of harvest happens we put more pressure on the few that survived last year, and there was very few 7-8yos running around this year... if that all makes sense. I haven't looked at the age class harvest stats in depth from last year but the overall average age class last year was about 0.2 years younger than years prior. as I recall, meaning we killed more young rams last year.
The weather was awful in many parts of the state (it rained 7 of 9 days I was out, and I couldn't see the mountain 5 of those days) The weather undoubtedly saved a few rams.
I'm pretty optimistic for next fall. I heard similar reports from others (plenty of younger rams), yet have heard dismal reports from some other areas of the state. Mainly the Talkeetnas and parts of the central and western AK range. The sheep hunters in TMA (Tok) had a really rough go at it, but the DCUA (Delta) hunters did well, just across the river, more or less. Center of areas are maybe 40 miles apart.
