Hawaii’s 9-foot invasive grass can produce 9,000 seeds per plant and fuel fires

 Once celebrated for its grazing benefits, Guinea grass has become a formidable threat to Hawaii’s delicate ecosystems. Since its introduction in the 19th century, it has proliferated, reaching impressive heights. This resilient perennial can generate thousands of seeds and rebound swiftly from fires, exacerbating wildfire risks by providing ample fuel across the islands. Its growth pattern serves as a stark reminder of the lasting ecological impact of imported plant species. Once celebrated for its grazing benefits, Guinea grass has become a formidable threat to Hawaii’s delicate ecosystems.
