Within 50’ feet either side of hiking trails the Contractor is to space all tree’s less than 10” inch DBH, to an 8’ foot x 8’ foot spacing regardless of species. Additionally, the Contractor shall retain a 1/10th acre patch uncut every 100’ linear feet along hiking trails. These retention patches are not marked or flagged. Contractor is required to directionally fell trees away from trail systems as much as possible. Should material be felled across any trail system, contractor must buck and remove material from within 10’ feet of hiking trail in the same operation period. NO CUT MATERIAL MAY REMAIN ACROSS HIKING TRAILS PAST THE DAY IT IS CUT. B. Felling Requirements (All units) Cut trees shall be completely severed from the stump. No hang-up "straps" will be permitted. 2. All felled trees shall be severed below the lowest live limb.

Cut trees shall be felled parallel to each other and not criss-crossed or jack-strawed. 4. Cut trees shall be felled away from unit boundaries into the units, roads, maintained trails, wildlife trails, fence lines, established land corners, and streams. Any trees felled on such areas shall be removed. Old roads that are closed can have cut trees fell across them. This will be on a case-by-case basis. 6. Bearing, section-line, or trail-blazed trees shall not be cut. Unit boundary trees with unit flagging can be cut if determined to be excess. 7. Snow damaged, bent over trees will be cut. 8.
