AI-generated description

Erigeron bonariensis, also known as Argentine fleabane, is an annual herb native to South America. In Qatar, it has been naturalized and is considered an invasive species. Studies have found that E. bonariensis grows abundantly in the country's urban areas, roadsides, and disturbed habitats, often forming dense stands. It can thrive in a variety of conditions, including high temperatures and saline soils, making it well-suited to Qatar's arid environment. The plant's presence in Qatar has been documented in various regions, including Doha and the surrounding areas, where it can outcompete native vegetation and potentially disrupt local ecosystems.
