Orange Hawkweed (Pilosella aurantiaca)

Despite its vivid appearance, orange hawkweed poses a significant threat to biodiversity and ecosystem health. It spreads aggressively, forming dense mats that outcompete native vegetation, reducing essential food sources for wildlife and livestock in rangelands and pastures. Additionally, it releases chemicals that inhibit the growth of surrounding plants. This invasive species can also escape from gardens, causing severe disruptions to natural landscapes.
