This data layer provides information on harvest and silvicultural activities in the US Forest Service. It is part of the Forest Service Activity Tracking System (FACTS) database, an activity tracking system that records, tracks, and monitors activities associated with timber sales, NEPA decisions, trust fund plans, hazardous fuels reduction treatments, invasive species mitigation, and some range activities. The database was queried to produce this data layer on harvest and silviculture activities (2001-2021). This data layer presents five types of harvest and silviculture activities: harvests, silvicultural exams and certifications, establishment and reforestation, stand improvement, nurseries and seed procurement, and miscellaneous.

Harvest and silviculture activities were identified in consultation with subject matter experts on each category of FACTS codes. The following activities were included in this category: 'Treatment Monitoring Plot' (4039), 'Research Areas' (4041), 'Coppice Cut (EA/RH/FH)' (4101), 'Coppice Cut (w/leave trees) (EA/RH/FH)' (4102), 'Patch Clearcut (EA/RH/FH)' (4111), 'Stand Clearcut (EA/RH/FH)' (4113), 'Patch Clearcut (w/ leave trees) (EA/RH/FH)' (4115), 'Stand Clearcut (w/ leave trees) (EA/RH/FH)' (4117), 'Shelterwood Preparatory Cut (EA/NRH/NFH)' (4121), 'Seed-tree Preparatory Cut (EA/NRH/NFH)' (4122), 'Shelterwood Establishment Cut (with or without leave trees) (EA/RH/NFH)' (4131), 'Seed-tree Seed Cut (with and without leave trees) (EA/RH/NFH)' (4132), 'Shelterwood Removal Cut (EA/NRH/FH)' (4141), 'Seed-tree Final Cut (EA/NRH/FH)' (4142), 'Overstory Removal Cut (from advanced regeneration) (EA/RH/FH)' (4143), 'Shelterwood Removal Cut (w/ leave trees) (EA/NRH/FH)' (4145), 'Seed-tree Removal Cut (w/ leave trees) (EA/NRH/FH)' (4146), 'Shelterwood Staged Removal Cut (EA/NRH/NFH)' (4148), 'Single-tree Selection Cut (UA/RH/FH)' (4151), 'Group Selection Cut (UA/RH/FH)' (4152), 'Two-aged Coppice Cut (w/res) (2A/RH/FH)' (4162), 'Two-aged Patch Clearcut (w/res) (2A/RH/FH)' (4175), 'Two-aged Stand Clearcut (w/res) (2A/RH/FH)' (4177), 'Two-aged Seed-tree Seed and Removal Cut (w/res) (2A/RH/FH)' (4183), 'Two-aged Preparatory Cut (w/res) (2A/NRH/NFH)' (4192), 'Two-aged Shelterwood Establishment and Removal Cut (w/ res) (2A/RH/FH)' (4193), 'Two-aged Shelterwood Establishment Cut (w/res) (2A/RH/NFH)' (4194), 'Two-aged Shelterwood Final Removal Cut (w/res) (2A/NRH/FH)' (4196), 'Improvement Cut' (4210), 'Liberation Cut' (4211), 'Commercial Thin' (4220), 'Salvage Cut (intermediate treatment, not regeneration)' (4231), 'Sanitation Cut' (4232), 'Special Products Removal' (4241), 'Harvest Without Restocking' (4242), 'Natural Changes (excludes fire)' (4250), 'Permanent Land Clearing' (4270), 'Administrative Changes' (4290), 'No Treatment Matrix' (4291), 'Remote Sensing Vegetation Mapping' (4302), 'Silvicultural Stand Examination' (4310), 'Pretreatment Exam for Reforestation' (4314), 'Pretreatment Exam for Release or Precommercial Thinning' (4315), 'Ecosystem and Midscale Inventory -
