Trial name: St. Mary’s residual basal area study in a mixed conifer stand (EP 1365) (aka St. Mary’s)
Trial objectives Installation name Ecosystems represented Tree species Silvicultural systems tested Post establishment treatments
How does the overstory and understory regeneration response to the level of residual basal area? 
  • Tree regeneration density and growth (natural and planted)
  • Light studies
  • Stand stability
  • Vegetation response
  • Ungulate use
