Trial website: http://wetbelt.unbc.ca
Installation name Estab. year Ecosystems represented Tree species Silvicultral systems tested Trial objectives
Lucille Mountain (EP 1119.01) 1991 ESSFmm1
  • Engelmann spruce
  • Sub-alpine fir
  • Clearcut
  • Group retention – 0.01ha to 0.1ha
  • Group selection/patch 0.02 ha
  • Irregular shelterwood
  • Single tree selection
To better understand how forest management affects these wet mountain forests:
  • Microclimate
  • Understory plant succession
  • Vegetation competition
  • Conifer regeneration
  • Windthrow
  • Arboreal lichen
  • Organic matter decomposition
Pinkerton Mountain (EP 1119.02) 1998 ESSFwc3
  • Sub-alpine fir
  • Hybrid spruce
  • Group selection/patch cut – 0.1ha to 0.3ha
  • Single tree selection
  • Uncut control
Determine effect of partial cutting on mountain caribou habitat:
  • Arboreal lichens
  • Regeneration
  • Vegetation
  • Stand structure
  • CWD
  • Wildlife trees
Bearpaw Ridge (EP 1119.03) 1999 ESSFwk2
  • Hybrid spruce

  • Western Hemlock
  • Group selection/patch cut – 0.1ha to 0.3ha
  • Single tree selection
  • Patch cut – 0.5ha to 1.0ha 
  • Uncut control
Examine effects of silvicultural systems on:
  • Stand structure, productivity, regeneration, understory, and damage agents
  • Biodiversity attributes, especially wildlife trees and CWD
East Twin, Minnow and Lunate study areas (EP 1119.03) 2000-01 ICHwk3 and ICHvk2
