This is a very solid foundation......^^^^^^
I've hunted a bunch from the ground and killed a lot of deer in that manner, but it is more challenging than a treestand because you are at eye level and can't get away with nearly as much. Some contend that camo and face cover isn't really necessary for bowhunting.....and that may be true for THEM in a treestand. But from the ground, a leafy type suit that is of the same tonal coloration as the foliage is advantageous. So is being still and doing whatever you can to be downwind and/or scent containment measures. That is a hot topic here on AT, because most either hunt from the air or are ground pounders out west doing spot and stalk. Ground ambush hunting is different from both and every little facet can make a difference in success or failure.
Building a little "fort" out of branches and such at the base of a tree is the way firearms hunters tend to ground hunt, but I've found being "in" a natural part of the habitat such as a blowdown or hedgerow or edge of a thicket gives much better cover. With a firearm or xbow, there isn't nearly the required movement as drawing a vertical bow, so as mentioned above, a bow holder that keeps your bow vertical and easily in reach is indeed valuable. When ground hunting, I always carry a folding saw and nippers, so I can cut a hole to sit and shoot through. It is easy to get caught up with lots of shooting "windows", but that also turns the backdrop to swiss cheese and makes your human form more visible. WATCH FOR POISON IVY in hedgerows.....don't ask.
Keep in mind a prey animal has eyes on the side of their head to see a much wider field of vision than predators. When you are timing your draw, make sure the animal is turned away, has something blocking their head or has moved on a bit so you are taking a quartering away shot. If they bust you on the ground, most often the "jig is up" and you won't be getting a shot at that particular animal.....plus they run off blowing the alarm to anything else in the region. However making a good shot at ground level and experiencing the elation of going about things in a more challenging manner is very rewarding......some of my fondest bowhunting memories are ground level kills.
