NEBIE Biodiversity - 140-203

Description: The goal of the NEBIE project is to establish a plot network to compare natural disturbances with a full range of extensive to elite silvicultural practices in the Boreal and Great Lakes - St. Lawrence regions of Ontario. This project addresses pertinent forest management issues including fibre production, species and genetic diversity, nutrient cycling and wildlife habitat. Members of the forest industry, universities, non-governmental organizations, Canadian Forest Service, and OMNR designed the project to rigorously test timber yields, environmental impacts and economics for a broad range of forest management intentsities. The NEBIE acronym stands for:

  • Natural Disturbance: Forest ecosystem responds without human inputs
  • Extensive: Minimum stocking is achieved and desired tree species are free of major insect pests
  • Basic: Minumum stocking is achieved and desired tree species are free of interspecific competition and major insect pests
  • Intensive: Near full stocking is achieved and desired tree species are free from inter and intraspecific competition and majot insect pests
  • Elite: Full stocking is achieved and desired tree species are from inter and intra specific competition, nutrient deficiencies and major insect pests.

The objectives of the NEBIE research project are to:

  • Determine the effects of natural disturbance and silvicultural practices on tree survival, growth, wood quality, and genetic diversity
  • Monitor the effects of silvicultural practices on microclimate, soil moisture and nutrient cycling, vegetation diversity and wildlife habitat
  • Develop a defensible database to accurately forecast allowable cut while maintaining ecological and economic viability

This research will help resource managers to:

  • Maintain or enhance fibre quantity and quality
  • Maintain soil and water resources
  • Conserve biological diversity
  • Reduce risk of losses to fire, insect, and disease
  • Maintain economic sustainability
