I would call almost a full year swing fairly significant, having gone from an avg age of nearly 9 to nearly 8. Considering the narrow bandwidth of age these animals can be harvested in, that is a big swing. As noted, with such a small pool of data these days, bigger swings one way or another are less significant than when we were killing 1200 rams a year.
The avg age in 2023 was 8.06 based on the numbers I looked at.
In 2023 117 out of 340, or 35%, of rams were less than 8 y/o.
2019 = 8.65
2020 = 8.76
2021 = 8.25
2022 = 8.18
2023 = 8.06
I'm no statistician, but that seems like a trend to me.
So what?
Valid question. I don't think the long-term affects of killing younger rams has been looked closely, nor has the potential impact on younger rams survival in relation to not having mature rams on the mountain.
Perhaps killing 5-6-7 year old rams isn't a significant biological problem for herd maintenance. There are still human factors and concerns to consider as well. Those dead young rams won't turn into mature 9+ year-old rams that a significant number of the remaining hunters, non-res and res, are looking for, hoping for.
Yet another trend is the % of rams killed that are 40" or better. In the past, 40" rams have made up as much as 6.5% of the total. That number has dropped to 4.5 to 5% in the last handful of years. For whatever that is worth.
