I support and practice QDMA on my property, and it is far from trophy management.
First and foremost QDMA recommends protecting ALL 1.5 yr old bucks, and SOME 2.5 yr old bucks. They also recommend keeping doe numbers in check, low impact hunting, improving habitat, ethical hunting, giving back, education and support youth hunting.
I do food plots, I have good deer numbers, great hunting and though only 4 years have alot of 2.5 year old deer or older running around than 1.5 year old's at the moment. In 4 years I have harvested 1 2.5 year old and one 3.5 year old bucks, multiple does and have had the best hunting of my life.
This season I firmly believe I have a 5.5 to 6.5 year old buck, on cam.... 1 3.5 yr old and several 2.5 year old bucks.
I dont believe in AR mandated by law. I believe a hunter has the right to decide what he/she wants to harvest. For my place I started with 8pt min to help hunters who couldn't tell between 1.5 and 2.5, but now that everyone who hunts can tell the difference it is simply 2.5 years or older.
Plots vs feeders are night and day and so it solid minded QDMA and Trophy Management!
