Ecosystems in the Columbia River Basin, and elsewhere, are under pressure from a range of human activities that are altering their function and impacting the species that rely on them. Ensuring the health of ecosystems is critical to conserving biodiversity.
In some cases, minor ecological impacts can be restored, in time, through natural recovery. Where the ecological impacts are more significant, natural recovery will not occur.
Ecosystem restoration is the process of intervening in an ecosystem to re-establish the naturally occurring mix of species and plants. This can be achieved by:
Prescribed burns, together with thinning (e.g., harvesting, spacing and slashing) are important tools used to restore grassland and open forest ecosystems. Riparian, stream and river (for fisheries), and wetland ecosystems are also the subject of active restoration programs in the Basin. The loss of specific habitat features, like large old trees for nest sites, can be addressed by constructing nest boxes or other interventions.
