Written by GovTribe AI ·

This document is a Contract Area, Hazard Reduction, and Site Preparation Map for the Mitchell Jackson Integrated Resource Stewardship Challenge (IRSC) Area 56, Subdivision 1 located on the Kootenai National Forest, Libby Ranger District in Montana. The map and accompanying planning table designate 96 cutting units totaling approximately 1,447 acres for timber harvesting and hazard reduction activities. The work involves felling trees, yarding operations via skyline or tractor methods, hand and mechanical slashing, excavator piling, scarification for site preparation, and landing cleanup across multiple specified units. Skidding and yarding methods are designated for each unit, with species designation or prescription-based designation methods applied to determine which trees are to be cut.

The cutting units employ various harvesting systems including skyline yarding (for steeper terrain), tractor yarding, and Over-the-Snow (ORSY) equipment operations. Work requirements include whole tree yarding, hand slashing of ninebark vegetation, excavator piling of residual materials, mechanical mastication, and scarification of soil. The map legend indicates protected areas including stream courses, trail improvements, utility protections, and areas with no cutting restrictions. The document includes closure specifications, road reconstruction and construction designations, and identifies unsuitable hauling areas and road use prohibitions. This planning document serves as the primary reference for defining scope, locations, and operational specifications for the hazard reduction and site preparation contract work.
