These are standard trail plan drawings from the U.S. Department of Forest Service for the Bon Secour National Wildlife Refuge (NWR) Centennial Trail project, detailing clearing and brushing specifications for trail construction. The documents provide technical diagrams and instructions for tree and vegetation removal, including specific guidelines for:

1. Tree Clearing (Sheet STD-912-01): Defines clearing limits for trees and logs, with instructions to start work at the east end and continue westward along an existing trail. Key specifications include: preserving trees outside designated zones, removing trees over 6-inch DBH (diameter at breast height), and using disposal methods D1, D4, and D5 for tree and woody debris management. Hazard trees are defined as standing or leaning dead trees larger than 90 feet in height.

2. Brushing Clearing (Sheet STD-912-02): Outlines brushing and mowing limits, specifying clearing to soil height with brush disposal via chipping (D4) or off-site removal (D5). Mowing debris can be left on-site. The drawings provide detailed cross-section views illustrating clearing zones, uphill and downhill limits, and cutting specifications for the trail corridor.
