C04f_Attachment 5 - Information Chart_1284LM26Q0098.xlsx

This is an Information Chart attachment that provides detailed silvicultural stand specifications for tree thinning and stand improvement activities on the Lolo National Forest, Seeley Ranger District. The chart specifies seven distinct work units totaling approximately 904 acres, divided into two treatment categories: five handpiling units (234, 420A, 420B, 237, and 415A acres) and two lop and scatter units (30 and 38 acres).

The prescription requirements establish uniform standards across all units, including a target leave tree spacing of 15 feet by 15 feet (14 feet by 14 feet for units 420A and 420B), a maximum diameter limit of 8.0 inches DBH for trees to be cut, and a minimum tree height of 1 foot for thinning. Species preference ranking prioritizes Ponderosa Pine and Western Larch over Douglas-fir, Subalpine Fir, Engelmann Spruce, and Lodgepole Pine, with preference given to trees 4 inches smaller in diameter than Lodgepole Pine. Handpiling units require 6-foot by 6-foot piles with a 6-foot minimum height, while lop and scatter units require slash reduction to 18 inches maximum height with bucking to 6-foot minimum and 8-foot maximum lengths. All slash treatment must maintain minimum pullback distances from infrastructure (2 feet from roads and slopes, 5 feet from culverts and trails), and piling must occur outside driplines of residual tree crowns with material greater than 6 inches limbed and bucked to maintain 5-12 tons per acre of down wood for long-term site productivity.
