Mount Seven/Ice road partial cutting research trials - uniform shelterwood trails

Trial Name: Partial cutting systems research in Armillaria root rot infected stands (EP 1186) (aka Ice Road and Mount Seven)
Trial objectives Installation name Ecosystems represented Tree species Silvicultural systems tested Post establishment treatments
  • Measure planted stock and natural regeneration response
  • Measure overstory residual tree response
  • Measure the relationship between light and tree growth
  • Monitor the vegetation development
  • Measure soil properties in response to harvesting method
  • Measure root disease (Armillaria ostoyae and Inonotus tomentosus) and impact on regeneration
Ice Road and Mount Seven
  • ICHmw2
  • MSdk
  • Douglas-fir
  • Western larch
  • Hybrid spruce
  • Western red cedar
  • Western hemlock
  • Irregular Uniform Shelterwood 
  • Patch cut
  • 4 levels of BA retention (zero, light, heavy and full)
  • two harvest methods – push-over and conventional hand falling
Comments: Impacted by windfall and Douglas-fir beetle in 2017 to 2018
