About this file
This document is a Detailed Unit Information Sheet for a site preparation mowing and road brushing contract on the Deschutes National Forest. The contract encompasses 18 base units and 9 optional units totaling approximately 712 acres across elevations ranging from 3,800 to 5,100 feet.
The primary work requirement is mechanical mowing of snowbrush, bitterbrush, and manzanita throughout all units, with mowing passes planned to minimize turning and soil disturbance. All trees 4.5 feet in height must be retained, and rock outcroppings and downed wood concentrations must be avoided; these unmowed areas are incorporated into the allowed 35% unmowed area per unit. Base units range from 8 to 77 acres with slopes varying from 5% to 25%. Additional requirements include trail maintenance provisions such as warning signs, retention of key trail-defining features, and debris removal from operations. Specific restrictions apply to Units 14, 15, 16, 17, 18, and 22, including boundary adherence for soil and hydrological concerns, wildlife treatment restrictions during April 1–August 30, avoidance areas, approved access requirements, and private property boundaries. The optional units (19–27) contain similar mowing specifications with selective restrictions noted for Unit 22 regarding private land boundaries and Unit 18 regarding trail management and pink avoidance areas.
