Utilization Levels. The utilization levels define the maximum xxxxx height, minimum top diameter (inside bark) and minimum diameter at breast height by species and are used in the analysis to calculate merchantable volume and are listed in Table 25. Table 25. Utilization Levels in the Xxxxxx TSA Analysis unit Minimum diameter at DBH (cm) Maximum Xxxxx Height (cm) Minimum Top dib (cm) Lodgepole Pine 12.5 15.0 2 10.0 Balsam 17.5 15.0 3 10.0 Spruce 15 15.0 4 10.0
Utilization Levels. Minimum merchantable utilization standards, are listed in Table 9.1. These reflect current standards and performance. Table 9.1 Utilization levels Leading Species Minimum DBH (cm) Maximum Xxxxx Height (cm) Minimum Top DIB (cm) Pine 12.5 30.0 10.0 Cedar 17.5 30.0 15.0 All others 17.5 30.0 10.0
Utilization Levels. The utilization levels modeled are listed in Table 21. The levels reflect current standards and performance. Note: dbh = diameter breast height, dib = diameter inside bark Table 21 Utilization levels Leading Species Minimum dbh (cm) Maximum xxxxx height (cm) Minimum top dib (cm) Pine 12.5 30.0 10.0 All others 17.5 30.0 10.0
Utilization Levels. The utilization specifications define the minimum diameter breast height (DBH), the maximum xxxxx height, the minimum top diameter and the minimum log length by species. These values are used to determine gross merchantable volume. Table 11: Utilization Standards Species Maximum Xxxxx Height (cm) Minimum DBH (cm) Minimum Top Diameter (cm) Aspen 25.0 17.5 10.0 Lodgepole pine 25.0 12.5 10.0 Spruce and Subalpine fir 25.0 17.5 10.0 All other species 30.0 17.5 10.0
Utilization Levels. The utilization levels (Table 29) define the maximum xxxxx height, minimum top diameter (inside bark) and minimum diameter at breast height by species and are used in the analysis to determine merchantable volume. Table 29: Utilization levels dbh (cm) xxxxx height (cm) dib (cm) All coniferous, except Pine 15 30 10 Lodgepole pine – except for small diameter licence 12.5 30 10 Lodgepole pine – small diameter licence 10.5 15 10 Deciduous 17.5 30 10 Leading Species Minimum Utilization Maximum Minimum top Data source and comments: • Table 29 reflects current district utilization standards, license requirements and current performance; and • Supply block D (Vanderhoof Forest District) utilization levels are not standard. Thus, incorporating them into volume projections will require specific work by the Ministry of Forests, Research Branch.
