Anecdotal
|
N/A
|
Dense populations of Glyceria maxima (reed manna grass) create rhizomal mats that can trap sediment faster than native species. This increased sedimentation can alter the flow of water, restrict or even clog small waterways and drainages, and cause flooding.

Experimental
|
Laboratory
|
Glyceria maxima (reed manna grass) uptakes available ammonium, which further decreases nitrifying activities. As G. maxima increases in a habitat, the availability of nitrogen in the soil could decrease.
