Also called the loop method for analyzing vegetation. Permanent line transects 100 feet in length were established 50 years ago for studying rangeland health and revisited. A 3/4-inch loop was lowered to the ground at 1-foot intervals, and contacts with plant tissues were recorded. Contacts were classified by species, litter, or type of abiotic material. Data comprised total contact counts for each species and material. Demonstrated by American botanist Thayne Tuason.
