Such a purely ecological path can be made of wood cuts.
The trunk is sawn into chumps by 10 centimeters, it is possible more, then you have to drive them deeper. Slices are treated with an antiseptic, the side of the cuts that will come in contact with the ground should be coated with resin, so the track will be more durable.
A trench of small depth digs along the contour of the future path, depending on the thickness of the cats used. A layer of sand is poured into it, for waterproofing, waterproof material is laid on it - roofing material or film. Very fine gravel is poured on top of this, wooden saw cuts are being dug. A few stacked saw cuts are sprinkled with soil, on top - with a mixture of granosevit with sand and well tamped.
