Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed [1] or transformed. [2] It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures.
The goal of geomorphic restoration is to eventually restore hydrologic processes important to riparian and instream ecosystems. However, this type of restoration can be logistically difficult: in many cases, the initial straightening or modification of the channel has resulted in humans encroaching into the former floodplain through development ...
Example: mine land restoration, lake restoration, and channel aquatic restoration with mature riparian corridors; Ecosystem modified in ecologically sound way. Example: selective timber harvest, biomanipulation, and introduction of predator fish to reduce planktivorous fish, increase zooplankton, consume algae or phytoplankton, and clarify the ...
Forest restoration may include simply protecting remnant vegetation (fire prevention, cattle exclusion etc.) or more active interventions to accelerate natural regeneration, [8] as well as tree planting and/or sowing seeds (direct seeding) of species characteristic of the target ecosystem.
Three important purposes of reforestation programs are for harvesting of wood, for climate change mitigation, and for ecosystem and habitat restoration purposes. One method of reforestation is to establish tree plantations , also called plantation forests.
An example is using willow in a stream corridor for sediment and phosphorus capture. [1] It aims to aid ecological restoration, the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action.
If a species integral to an ecosystem has been lost due to extinction, a related species will be placed to fulfil the same role and re-establish the ecosystem function. These typically range from a related sub-species to another species within the same genus. [1] An example of such is the ecological services herbivores provide.
This will involve a paradigm shift in the relationship between humans and nature. The ultimate goal of rewilding is the restoration of functioning native ecosystems containing the full range of species at all trophic levels while reducing human control and pressures. Rewilded ecosystems should—where possible—be self-sustaining.
