  "term_source": "Invasive Plant Species",
  "definition": "1. A (plant) species that is brought into an area, usually by human movement, and begins to out compete native species.\n\n2. Plants that are not part of (exotic) or a minor component of (native) the original plant community or communities that increase above what’s expected given the normal range of variability of a site.\n\n3. A plant species must interfere with management goals to be considered invasive. A nonnative species is not invasive simply because it is present in a wildland ecosystem; it must also have impacts on the ecosystem that interfere with attainment of management objectives. Fire-related impacts of nonnative invasive plants may include changes in the species composition or structure of postfire plant communities, especially when these changes occur at the expense of native species, and changes in fuel properties that alter fire behavior or fire regimes.\n\n4. With respect to a particular ecosystem, any species that is not native to that ecosystem, and whose introduction does or is likely to cause economic or environmental harm or harm to human health.\n\n5. Non-indigenous plant or animal species that can harm the environment, human health, or the economy.",
