Classification of Large Litter
For purposes of classifying litter, and in accordance with the methods used in previous litter surveys conducted, large litter is defined to be that which is over 4 square inches in size. Three templates are provided each survey team of an area of 4 square inches in rectangle, square and round shapes to aid field teams.
Teams record the categories of large litter found on the site, for later entry in to a specialized database program for analysis and reporting.
Classification of Small Litter
Small litter are those pieces of debris that were less than 4 square inches in size. The nature of the small litter survey is to sample the small litter in three transacts, or slices, of the site. A frame made of 1/2 inch P.V.C. plastic tubing is constructed to act as a frame. The frame is 1 foot wide and 5 feet long. A surveyor looks for and counts small litter in three samples, one at the start of the site, one at the mid-point and one at the end of the site. At each transact section; three flips of the frame are done, thus surveying 15 square feet of the site - repeated three times.
