what type of woods?, what is the age of the forest? how much undergrowth etc.
How much land do you have, and how much trails do you plan on making, and how much time are you going to have for maintenance. How many people are going to be using this? and what equiment do you have availalbe for construction and maintenance. Is there any water and other maintenance issues.
I'm doing a similar job on my property. most of my property is red alder between 2 and 6 inches DBH and nearly one every square foot. Inbetween I have salal, sword fern, salmon berry and the occational blacberry (both native and himilayan)
I plan on havein trails at least 4' and usually 6-8 feet wide. I can easily loose 2-4 feet of width due to branch encrochment per year, so clearing an 8' wide trail can still force people to walk single file sometimes.
My plan is to have paths smooth enough to be able to ride mountian bikes on.
I start by planning out where it is going to go, flagging the path at various sections. Cutting down all the trees in the path. and either pulling up the stumps or cutting them flush wiht the ground. In the case of some old bigger stumps, I simply pile up dirt over them to make a big bump out of the hill.
I then drive teh tractor over the path, ripping out whatever small stumps, and other roots, and flattening the trail. Warning. Pulling out a root ball removes dirt and creates a hole.
Then I fill in all of the holes and low sections with dirt from other places. A hole will collect water and become a mud puddle.
In the summer this will dry out and become very dusty when walked on. some sort of surface covering is needed. Grass does not grow well in the mostly full shade of my trails. I use wood chips. Last year I bought a couple truck loads of wood chips. This kept the dust down really well. This year I hope to rent (or buy I hope) a
chipper and chip up a lot of the alder that I cut down making the trail.
