The project consists of felling and bunching trees using a tracked feller-buncher, skidding trees using a tracked or rubber tired skidder, delimbing using chainsaws or a stroke delimber, piling slash using the stroke delimber and skidder - trees by description and piling of slash as described below. The project consists of 50 acres of treated forest, not including leave Islands, these are in units shown on the map. The contractor shall fall all trees including Ponderosa Pine and Juniper trees except the leave trees as described below. Retain all trees over 16 inches DBH regardless of spacing unless approved individually by the Forest Officer. Remove all trees except LEAVE TREES and trees over 16 inches DBH including all regen and unmerchantable trees and Juniper trees. LEAVE TREES are to be 60 to 120 - foot variable spacing of boles with a 30 - foot minimum crown spacing goal. LEAVE TREES will be a mix between 6 inches DBH to 16inch plus DBH. LEAVE TREES will be of good form and have a single terminal leader and be free of obvious insect or disease. Do not leave defective trees for leave trees unless they are unique in nature.
