“Land design and management informed by permaculture principles tends to regard naturalized species of plants as assets that should be managed to stabilize water and soil, build biomass, fix nutrients, ameliorate microclimate and provide habitat, fodder, fuel and food in the early stages of system development.While naturalized species may be given a lower value in permaculture design than species regarded as indigenous to the site and region, the typical designation of naturalized species as ‘invasive species’ or ‘environmental weeds’ is typically rejected as anti-ecological thinking.”
