A06_Attachment_3_-_HSO_Limbing_Info.xlsx

This is an attachment containing detailed specifications for tree limbing work across multiple orchard and forest units under the 2026 HSO (Hazardous Fuels and Silviculture Operations) and TSO (Timber Sale Operations) program managed by the Department of the Interior Bureau of Land Management Oregon-Washington.

The work encompasses three operational categories totaling 5,813 trees requiring pruning across 35 whorls to be removed. The 1st Generation units include nine orchards (I11-Nestucca through B93-Zone 2/3 WWP) requiring 1,409 trees pruned with 10 whorls removed and 1,409 total whorls to address. The Consolidation phase consists of eleven forest management units (C43 Cascade Low SP through I61 N. OR Cascades WH) requiring 3,650 trees pruned with 19 whorls removed and 6,873 total whorls to address. The Preservation category includes three preservation units (P-01, P-02, V-98) requiring 754 trees pruned with 6 whorls removed and 1,617 total whorls to address. Each unit specifies the number of trees to prune, the number of whorls to remove per tree, and the cumulative whorls to address per orchard or forest unit, providing contractors with precise scope requirements for bidding and execution planning.
