The Glyceria maxima wasw located in the upper section of the lake along the western shoreline on shoreline proterty of the Norther Highland American Legion State Forest. It was growing in a mucky substrate and in a water depth of 1? ? 3? of water. Since we did not find many Glyceria plants, I got out of the canoe and hand-harvested all of them that I could find, including its root mass, totaling about 15 plants. Unlike other AIS with dense roots systems, I was surprised by Glycerias lack of root structure and how easily they pulled out of the sediment. I also found Purple Loosestrife and Yellow Iris growing in amongst the Glyceria and native vegetation and obtained samples of both.

About
Reed Manna Grass
Reed manna grass is a semi-aquatic, perennial grass with unbranched stems that grow up to 8’ tall. It has a reddish tint on the lower parts of the stems. Tall manna grass invades wetlands, including swamps, lakes, ponds, slow-moving rivers, creeks, ditches, and wet pastures, where it forms monospecific stands that are capable of crowding out native vegetation. It degrades wetland habitats because it is not suitable for nesting and is a poor food source for wildlife. Tall manna grass has been sold as an ornamental in a variegated variety. Young shoots can cause cyanide poisoning in cattle if used as forage.
