Active restoration is defined as physically changing a river channel or its floodplain; for example, removing a levee or placing boulders or logs in a river or changing the channel’s location or shape. (Passive restoration, on the other hand, is defined as changing land management and then allowing the river to recover over time.) The first steps in restoration often involve protecting areas with intact processes and high-quality habitat and reconnecting isolated fish habitats made inaccessible by culverts or other artificial obstructions. Managers also focus first on passive restoration measures. Active measures are usually employed only when passive restoration is not enough or would take too long to yeild results. Often managers use a mix of passive and active restoration measures.
