Interesting comments....and I gotta say...I agree with 50% and disagree with 50%.
Each unit is significantly different from season to season with regards to hunter pressure, types of hunters, #s of hunters per season, type of pressure each season and # of animals harvested....throw in weather and it gives all the previous data points 3 more variables.
The ONLY way to know whats going on in a GMU is to spend time in it. CODAK mentions 3 years and that pretty much spot on for the minimum.
Types of hunters is huge in my opinion for how my season goes. There are the loud ones, ones that only hunt 48 hours then give up, ones that only stay on trails, those that only stay with 1/2 mile of camp, those then rent horses and go down the trail 24 hours prior to the opener acting like elk dont know what the sound of metal on rocks sounds like, those that have no clue about scent control and my all time favorite....the bugle from the trail all day and wonder why no bulls respond to that. All that factors into the archery muzzle loaders success #s.....in that particular GMU.
CDOW stats.....I think more people just plain flat out dont respond to the questionnaire vice lie or tell different stories to mess data up. Regardless its info to take in and analyze but I'm not to sure if id be using it as a determining factor. With regards to using that data for herd management, CDOW knows its faulty and leans heavily on the herd counts on winter range to help with the management plan for each DAU.
That being said.....in the limited entry GMU I've hunted in the past 7-10 years, every September......one thing has always held true regardless of resident or non resident....archery guys all are around 10% success if they hunt the standard 10-14 days of the season. If they spend the whole season or over 20 some odd days in there hunting (sometimes the whole season) that number jumps to 25-30%. If the muzzle loader guys hunt like an archery guy they have a roughly 25-30% success rate with their either sex tag. If the muzzle loader guys hunt like they have a rifle in hand....the success rates drop to 10% or below.
Just what I've seen. Hope that sheds a little light.
