  1. Best available estimates. Accuracy varies, depending on the pest. Many more pests are endemic throughout most forests. Detailed measures of the intensity of infestation are not available.
  2. Best available estimates of current annual losses as compiled by Forestry Canada except for the Cariboo Forest Region values. Accuracy varies, depending on the pest.
  3. Best available estimates of current annual losses as compiled by Forestry Canada. Accuracy varies, depending on the pest.
  4. Best available estimates of current area affected are compiled from Ministry of Forests and Canadian Forest Service data. Although more insects and diseases are endemic, detailed measures of the intensity of infestation are not available.
  5. Estimates of losses compiled by Canadian Forest Service, Forest Insect and Disease Survey.
  6. Infested area estimates include parks and other protected areas.
  7. Estimates of losses provided by Ministry of Forests’ regional offices.
