This is an interesting topic, I really never thought about creating Buck beds or doe beds for that matter. But I can tell you where I find them, if that matters.
I do the vast majority of my deer hunting on state land, and here in Mich. that varies quite a bit in regards to cover and terrain. My favorite spot of all that borders private land is a big buck mecca and has been for over 20yrs. Also I was lucky enough to meet the owners of the surrounding private lands and secured permission to bow hunt on it only.
These pieces of private land all had one thing in common on them. They used to grow christmas trees on them, that consisted of five ten and twenty acre plots. After the market for the trees tanked they never harvested them and continued to just let them grow. In between these plots the state land was planted in red pine that were interspersed with huge white oak and beech trees.
Now, as the red pine began to mature they lost there holding and bedding desireability, but the overgrown christmas trees(scotch pine) still hold uncanny bedding traits. The does bed there all the time and the big bucks know it! During the last week of Oct. and the first week of Nov. you catch the bucks cruising from one patch to the other in search of those first esterous does.
During the most severe of weather conditions, from high heat to knee deep snow you'll find the deer here. Also there is a small creek that runs near by so there is a year round water source. You would think that there was no food available to them but you would be suprised at the amount of lichens, mosses and mushrooms that grow amongst them, that deer will eat!
Now it's been my observation over the years that during the heavy chase phase of the rut, the does will run from thinner cover into these thick spots to shake the bucks off their tail. The older, wiser bucks will already be staged up in here just waiting for the fresh meat to be chased to them.Intercepting the does and running the younger bucks off!
I guess I'm rambling a bit, so back to what I believe was my point to start with. I think If I were to attempt creating a bedding area, I would use scotch pine trees.They will grow in just about anything, except very moist ground and muck! and grow especially well in very sandy soils. They also are very cheap to buy in bulk seedling stage and grow appx. 1ft a year. After 6 or 7 years I would top them to slow there upward growth. The deer don't usually brouse these trees until they get much older so I wouldn't be to concerned about them eating to oblivian and destroying the trees altogether. just my 2 cents worth.
Like gramps used to say, "Why is it there's never time to do it right, but there's always time to do it over?"
