Native plant species— The term native plant species means indigenous terrestrial and aquatic plant species that evolved naturally in a defined native ecosystem.

Nonnative plant species— The term nonnative plant species means a plant that has been introduced by humans to a location outside its native or natural range and may, depending on relevant facts and circumstances, include a species introduced from another continent, ecosystem, seed zone, or habitat within an ecosystem.

Plant materials— The term plant materials includes, with respect to a native plant species or a nonnative plant species, such a plant or its seeds, eggs, spores, or other biological material capable of propagating that species.
