4220 Phragmites australis australis Competition Observational Field Due to its competitive nature, Phragmites australis has replaced over 90% of Typha/Scirpus reed marshes in just 30 years. Riverbanks and creeks are now dominated by P. australis monocultures in the area. Connecticut River, USA 23335
4222 Phragmites australis australis Competition Observational Field Both density and frequency of submerged vascular plants (Ruppia maritima and Eleocharis parvula) and macroalgae (Enteromorpha sp. and Vaucheria sp.) was much higher in creeks without Phragmites australis. Connecticut River, USA 23335
4228 Phragmites australis australis Competition Observational Field Phragmites autralis has replaced native Spartina-dominated stands in marshes with man-made tidal alterations throughout the New England region of the United States. New England Region, USA 36124
4231 Phragmites australis australis Competition Observational Field Once introduced, Phragmites australis quickly outgrows native plant communities, changing them from lower mixed-statured communities into tall grass monocultures. North America 30163
4247 Phragmites australis australis Competition Anecdotal N/A Phragmites australis is considered a primary weed of rice, corn, and cotton in Russia, sugarcane in Australia, and sugar beets in Zimbabwe and the Netherlands. 28764
4289 Phragmites australis australis Competition Observational Field Phragmites australis displaces native plant communities in Lake Erie. Long Point, Lake Erie, Ontario, Canada 36123
5869 Phragmites australis australis Competition Anecdotal N/A P. australis reduces wetland plant diversity Crown Marsh, Long Point Bay, Lake Erie, Ontario 40186
5870 Phragmites australis australis Competition Observational Field In post industrial mine remediation areas of Towice, Poland, areas dominated by P. australis had fewer species than areas without P. australis. Silesian Upland, Katowice, Poland 40782
5871 Phragmites australis australis Competition Observational Field In littoral marshes in Poland P. australis was able to overgrow new sites and outcompete native species through vegetative propagation. Jeziórko Sulphur Mine, Poland 40228
5872 Phragmites australis australis Competition Experimental Laboratory The root exudates from P. australis negatively impacted the growth of M. Ericifolia. Negative effects were also observed from leaf litter for M. Ericifolia, R. Conglomeratus, and L. Sativa 40707
5873 Phragmites australis australis Competition Experimental Laboratory P. australis did not have negative competitive impacts on S. hermaphrodita in the rhizome but did outcompete the species via above ground shading. 40717
5874 Phragmites australis australis Competition Experimental Laboratory Propagule pressure from invasive Phragmties has a stronger impact on community outcomes than seed dispersal and low water levels increasing the species competitive advantage. 40720
5875 Phragmites australis australis Competition Experimental Laboratory Invading P. australis had a neutral or negative impact on the survival of native wetland plant seedlings including native Phragmites. 40738
5876 Phragmites australis australis Competition Observational Field Post monsoon seasons in South Korea resulted in P. australis replacing native vegetation (Suaeda japonica and other species) and decreasing their populations. Nakdong River estuary, South Korea 40758
5877 Phragmites australis australis Competition Observational Field P. australis decreases the competitiveness of native Melaleuca ericifolia in Australia by disrupting the formation of mycorrhizal associations in the soil. Cherry Lake, Victoria, Australia 40803
5878 Phragmites australis australis Competition Experimental Laboratory P. australis reduces invasive Spartina densiflora establishment with a garden experiment showing all plants dying after forming shoots. This is most likely due to P. australis outcompeting for soil based resources. 40821
6800 Phragmites australis australis Competition Anecdotal N/A Phragmites forms dense monocultures and is capable of dominating wetlands within a few years. 27611
6801 Phragmites australis australis Competition Anecdotal N/A Phragmites threatens the biodiversity of Michigan’s coastal and interior wetlands. It displaces native species including sedges, rushes, and cattails. This reduces wildlife habitat diversity, resulting in loss of food and shelter for native wildlife. Michigan, USA 27561
6802 Phragmites australis australis Competition Anecdotal N/A Phragmites may reduce and degrade wetland wildlife habitat, due in part to its dense growth habit 27613
9510 Phragmites australis australis Competition Observational Field Phragmites australis australis crowds out native plant species. United States 42993
