Daily, dried grasses should be cut, and brought back to scatter around the camp, and if using a tent, fresh grass and pine bows can be cut to put under bedding to make a softer sleep. If sleeping on the ground, use a shovel, or your knife to soften the ground by digging it up, and scooping out dirt in a shallow hole for your backside.
A 12 inch thick layer of dried leaves and grasses will insulate your sleeping bag well, and protect you from the cold ground. Put fresh dead leaves down every day, and hang the sleeping bags out to dry, too. Those leaves you remove from where your bed was can be spread around the camp to fight back the mud, and keep you from slipping in your moccasins.
