4221 Phragmites australis australis Habitat Alteration Observational Field Due to the tendency of Phragmites australis to replace Typha/Scirpus reed marshes, muskrat dens, which were once plentiful under the native grasses, are now rare. Connecticut River, USA 23335
4223 Phragmites australis australis Habitat Alteration Anecdotal N/A It is suggested that the presence of Phragmites australis on creek banks and in marshes could have an impact on the fish populations. Connecticut River, USA 23335
4226 Phragmites australis australis Habitat Alteration Observational Field The biomass of insects inhabiting Phragmites australis stands is high. Hudson River, New York, USA 35919
4229 Phragmites australis australis Habitat Alteration Observational Field Due to its tendency to consume litter and peat, Phragmites australis-dominated sites contributed to the lower relative marsh surface elevation in man-made tidal alterations New England Region, USA 36124
4232 Phragmites australis australis Habitat Alteration 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
4250 Phragmites australis australis Habitat Alteration Observational Field The spread of Phragmites australis has limited and changed suitable nesting habitats of native turtle species through habitat alteration, including Apalone spinifera, the spiny softshell turtle. Long Point National Wildlife Area, Lake Erie, Ontario, Canada 31633
4251 Phragmites australis australis Habitat Alteration Observational Field Phragmites australis has been shown to displace native species, including rushes, sedges, and cattails, reducing overall plant diversity. North America 27561
4255 Phragmites australis australis Habitat Alteration Observational Field Phragmites australis stabilizes soil, which can protect against erosion. Phragmites australis stabilize soils against erosion (Kiviat 2010). 27608
4258 Phragmites australis australis Habitat Alteration Observational Field Insects, birds, and muskrats use Phragmites australis for shelter and nesting material. 27608
4285 Phragmites australis australis Habitat Alteration Anecdotal Field Phragmites australis can act as a sediment trap, preventing erosion and acting as a buffer for wetlands from sea-level rise. Chesapeake Bay 22662
4287 Phragmites australis australis Habitat Alteration Anecdotal N/A Phragmites australis has the ability to cause habitat loss and can negatively impact bird populations. Gulf Coast, United States 35917
4288 Phragmites australis australis Habitat Alteration Anecdotal N/A Phragmites australis can act as a sediment trap, preventing erosion and acting as a buffer for wetlands from storms. Chesapeake Bay 35917
4290 Phragmites australis australis Habitat Alteration Observational Field Phragmites australis displaces native plant communities in Lake Erie. Long Point, Lake Erie, Ontario, Canada 36123
4291 Phragmites australis australis Habitat Alteration Observational Field In fields and marshes where Phragmites australis has replaced native vegetation stands, bird population abundance is lower and bird species compositions are altered. Long Point, Lake Erie, Ontario, Canada 36123
4292 Phragmites australis australis Habitat Alteration Observational Field Phragmites australis disrupts the nesting habitat of the Diamondback Terrapin (Malaclemys terrapin). It also increases shading of the nesting sites, which changes nest temperature, shifting clutches to be predominately male. Chesapeake Bay 32607
4558 Phragmites australis australis Habitat Alteration Observational Field The dense aggregation of Phragmites australis in Rend Lake in Southern Illinois caused poor habitat quality for recreation and native plants and animals, and the lake was closed to recreation for the treatment of the plant in August of 2021. Rend Lake , Southern Illinois 36857
5714 Phragmites australis australis Habitat Alteration Anecdotal N/A In the Ottawa Refuge, Ohio, Phragmites australis australis grows extremely dense mats of vegetation which can prevent fish and frogs that take shelter and lay their eggs in between aquatic plants. The dense mats of Phragmites australis australis can also decrease the amount of food and foraging space for wading birds. Ottawa Refuge, Oak Harbor, Ohio, United States 17893
5879 Phragmites australis australis Habitat Alteration Anecdotal N/A P. australis converts wetland areas into terrestrial habitats. 40186
5882 Phragmites australis australis Habitat Alteration Experimental Laboratory P. australis did not change C fluxes and pools in comparison to uninvaded systems. 40246
5886 Phragmites australis australis Habitat Alteration Observational Field P. australis was the same or worse (during low water levels) than native S. alterniflora at attenuating waves and protecting coasts. Franklin Point State Park, Maryland, United States 40755
5887 Phragmites australis australis Habitat Alteration Observational Field P. australis cover of 50% or more had a negative effect on Malaclemys terrapin nest reducing the temperature of nest increasing the predominance of male hatchlings. Did not lead to increased root growth into nests Fisherman Island, Chesapeake Bay, Virginia, United States 36207
5888 Phragmites australis australis Habitat Alteration Observational Field P. australis has a deeper rooting depth than native species and produces a higher amount of CO2 from deep SOM mineralization meaning P. australis is potentially depleting deep C pools sequestered by native species. Kirkpatrick Marsh, Chesapeake Bay, Maryland, United States 40767
5890 Phragmites australis australis Habitat Alteration Observational Field P. australis decreased native plant density and impacted soil microbial communities especially with increased salinity. Louisiana, United States 40785
5891 Phragmites australis australis Habitat Alteration Observational Field P. australis provides habitat for birds that are shrub-nesting, ground, and foliage gleaning species but reduces habitat for marsh nesting species. Long Point, Ontario, Canada 36123
5905 Phragmites australis australis Habitat Alteration Observational Field Invasive P. australis led to a biochemical production of amorphous silica particles at a rate that was 1.5 and 2 times higher than native willow and Phragmites respectively. Platte River, Nebraska, United States 40798
