Techniques and Equipment for Wilderness Travel with Stock
To be sure that an area is not overgrazed, leave 3 inches (7.62 centimeters) of grass in a rough, tufted appearance. Do not allow animals to graze in areas where the grass looks short and smooth. Avoid wet, marshy areas and lake edges, because they are very susceptible to damage. To prevent water pollution and bank erosion, tie stock well away from water sources. Use a collapsible bucket to water stock or lead them to water at a rocky spot where little bank damage will occur.

If picket stakes are used, they should be moved frequently to prevent overgrazing.

A highline is an effective, low-impact method for containing stock. Two-inch (5.08 centimeter) wide, nylon tree-saver straps with adjustable buckles allow stock users to set up a highline quickly and easily with little or no damage to the tree. A rope is run between the straps, tied with a quick-release knot, and pulled taut. The rope should be placed approximately 7 feet (2.14 meters) above the ground. Set up the highline where the soil is hard and rocky. Don’t tie stock directly to trees. Many managers have adopted strict regulations concerning picketing stock, grazing stock, and using corrals.
