Impact ID Scientific Name Impact Type Study Type Study Location Impact Description Geographic Location Reference
3337 Myriophyllum spicatum Competition Experimental Laboratory Myriophyllum sibiricum suppressed biomass accumulation of M. spicatum in outdoor mesocosms. 20801
3400 Myriophyllum spicatum Competition Observational Field Decreasing plant species diversity was associated with increasing Myriophyllum spicatum frequency over three years. 10169
3402 Myriophyllum spicatum Competition Observational Field Najas marina has a stronger competitive effect on Myriophyllum spicatum than vice-versa. 20325
3405 Myriophyllum spicatum Competition Observational Field Native plant species richness and density decreased over three years associated with Myriophyllum spicatum increase in abundance at Lake George, NY 20402
8718 Myriophyllum spicatum Competition Anecdotal N/A Myriophyllum spicatum (Eurasian watermilfoil) is tolerant of low water temperatures and begins to photosynthesize and grow early in the spring. 19120
8719 Myriophyllum spicatum Competition Anecdotal N/A Growth in spring allows Myriophyllum spicatum (Eurasian watermilfoil) to reach the water's surface before native plants and create a dense canopy to out-compete for sunlight and space. 35275
8720 Myriophyllum spicatum Competition Anecdotal N/A Growing early in the spring gives an advantage that allows Myriophyllum spicatum (Eurasian watermilfoil) to form dense beds with stem densities in excess of 300/m2 in shallow water, essentially excluding other plant species. 10310
8721 Myriophyllum spicatum Competition Experimental Laboratory In small tank experiments, the native Myriophyllum sibiricum (northern watermilfoil) appears competitively superior. In the field, however, Myriophyllum spicatum (Eurasian watermilfoil) has replaced M. sibiricum over much of the temperate range of this species in North America. 20801
8722 Myriophyllum spicatum Competition Anecdotal N/A Suppression by Myriophyllum spicatum (Eurasian watermilfoil) of native plant communities in the field can occur in just a few years. 10310
8723 Myriophyllum spicatum Competition Anecdotal N/A Myriophyllum spicatum (Eurasian watermilfoil) has difficulty becoming established in existing populations of native plants. 35279
8724 Myriophyllum spicatum Competition Anecdotal N/A Myriophyllum spicatum (Eurasian watermilfoil) thrives in waterbodies that have experienced a disturbance, such as nutrient loading, intense plant management (i.e. yard management on private property), heavy recreational use, and/or fluctuating water levels. 35275
8725 Myriophyllum spicatum Competition Anecdotal N/A Myriophyllum spicatum (Eurasian watermilfoil) is found in hundreds of inland lakes in Michigan. Michigan, USA 35279
8726 Myriophyllum spicatum Competition Anecdotal N/A The Minnesota Sea Grant states that Eurasian watermilfoil (Myriophyllum spicatum) is not problematic in ecosystems with sandy or low sediment fertility. 35277
9306 Myriophyllum spicatum Competition Observational Field Myriophyllum spicatum grows in dense stands which excludes native aquatic vegetation and potentially wildlife species that use that space. 42811
9339 Myriophyllum spicatum Competition Observational Field In Lake George, New York, the increase in coverage of Myriophyllum spicatum from 30% to 95% coverage resulted in significant decline of native plant species density. Lake George, NY 42843
9340 Myriophyllum spicatum Competition Observational Field In Lake Waneta, New York, the presence of Myriophyllum spicatum reduced the presence of native species. Lake Waneta, NY 42843
9341 Myriophyllum spicatum Competition Observational Field In Lake Lamoka, New York, the presence of Myriophyllum spicatum reduced the presence of native species. Lake Lamoka, NY 42843
