Revegetation is a broad term that describes a variety of practices that we use to modifying vegetation. A typical revegetation effort involves three general components: a disturbance to create a niche to introduce new species, propagation of that species onto the site with seeds, cuttings, or rooted stock, and some kind of aftercare (either supplemental water and nutrients, or more disturbance) to favor the introduced species. While we are focused on discrete projects, revegetation occurs in the context of natural vegetation evolution, driven by climate, hydrology, genetics, dispersal, competition, stress, and ongoing disturbance regime. This page is a master topic page to organize information on the wiki to support revegetation practice.
