Ecological Relevance

photo of forestDetermining ecological relevance in specific cases requires professional judgment using the three criteria and based on site-specific information, preliminary surveys, or other available information.

Ecological relevance is linked to:

  • Nature and intensity of effects.
  • Spatial and temporal scales of effects.
  • Potential for recovery.
  • Level of organization potentially affected.
  • The entity's role in the ecosystem.

For example, if a change in a particular ecological entity could cause multiple or widespread effects, that entity might be part of a more valuable (relevant) endpoint. This entity could be helpful in identifying the potential cascade of adverse effects the endpoint could involve. Try the Activity below and read the In-Depth note to expand upon the importance of ecological relevance.
