© Parks Canada

A healthy ecosystem has its native compents intact, including abiotic factors, biodiversity and ecosystem proceseses. A healthy ecosystem has ecological integrity. A system with ecological integrity is characteristic of the natural region and likely to persist or rebound from change or disturbance. Tiny changes in the forest ecosystem can compromise its ability to withstand or rebound from stresses such as:

  • drought
  • insects
  • disease
  • climate change
  • human interaction

Ensuring that habitats within national parks have ecological integrity is a large part of the Parks Canada mandate.
