  2. Definitions • Restoration is the process of intentionally altering a site to establish a defined, indigenous, historic ecosystem. The goal of restoration is to emulate the structure, function, diversity, and dynamics of the specified ecosystem. • Creation establishes a historical ecosystem on lands that did not previously support that ecosystem. (from California Society for Ecological Restoration)

  3. Definitions • Restoration can be divided into two activities, res-establishment and rehabilitation. • Re-establishment returns historic/natural functions to a site as previously existed. • Rehabilitation improves the general suite of functions of degraded site. Usually, this activity results in less disturbance to a site.
