Restoration vs Protection

Restoration and protection are two important elements for improving watershed health. Restoration refers to work done to restore historical natural systems that have since degraded. Protection refers to focusing efforts on preserving what is currently present so that it does not further degrade. This map can help inform resource managers with the information they need to make critical decisions pertaining to the Chehalis basin.
