Ecosynthesis is the use of introduced species to fill gaps in a disrupted environment, with the aim of speeding up ecological restoration and reducing further damage. A simple example is planting willow along a stream to help capture sediment and phosphorus.

It is part of restoration ecology, which uses active human steps to renew damaged ecosystems. This includes selecting and placing plants, mapping vegetation, improving habitats, and remediation and mitigation to support recovery.

Key ideas include: revegetation (reestablishing plants where they were lost, often to control erosion), habitat enhancement (making a site more suitable for specific species), remediation (improving an existing ecosystem or creating a new one to replace a damaged one), and mitigation (legal steps to compensate for the loss of protected habitats or species).

A famous example of ecosynthesis effects is a trophic cascade. In Yellowstone National Park, wolves were reintroduced. Their presence reduced the elk population, which allowed vegetation like aspen to recover, helping restore the ecosystem’s balance.
