Family: Poaceae
Andropogon bicornis, commonly known as West Indian foxtail grass or Barbas de Indio, is an invasive species in Hawaii. Invasive species are non-native plants, animals, or organisms that can harm the local environment, economy, or human health. When they are introduced to new ecosystems, they often outcompete native species, disrupt ecological balance, and cause economic damage.
Barbas de Indio grass is native to tropical regions in the Americas, and it has become invasive in various parts of the world, including Hawaii. This invasive grass can outcompete native vegetation, alter the structure of natural ecosystems, and impact wildlife habitats. It can also pose a fire risk in certain areas.
Efforts are typically made to control and manage invasive species like West Indian foxtail grass in Hawaii through various methods, including manual removal, herbicide application, and ecological restoration projects. These efforts aim to protect native Hawaiian ecosystems and biodiversity.
High Risk Traits:
- Naturalized on Kaua'i and Hawai'i
- Thrives in tropical/subtropical climates.
- Tolerates a wide range of soil conditions.
- Documented weed of pastures and sugarcane.
- Unpalatable to grazing animals, reducing forage value.
- Increases fire hazard in ecosystems.
- Forms dense, monotypic thickets.
- Reproduces by viable seed and is self-compatible.
- Hybridizes with related species.
- Seeds dispersed by wind, water, and through animal guts.
- Tolerates and benefits from fire and mutilation.
Low Risk Traits:
- Lacks spines, thorns, or burrs.
- Not parasitic or toxic.
- Does not reproduce vegetatively.
