NPS Photo Phragmites (Phragmites australis) Phragmites, Phragmites australis, also known as Common Reed, is an aggressively growing species, which outcompetes many other native plants. It can grow to a height of ten feet, and often grows in disturbed areas. It forms a "monoculture," which lowers biological diversity. Phragmites reproduces mainly by underground runners, with one plant often giving rise to dozens of shoots. It is also the main fuel for fast-moving and dangerous grassland fires at Gateway. |
