Widgeon Grass (R uppia m aritima) Widgeon Grass is mostly found in freshwater but also exhibits a high tolerance for salinity and therefore can be found in Texas estuaries. Salt marshes can be extremely difficult places to live because of wide daily fluctuations in salinity, water, temperature, and oxygen. Widgeon grass Dominant or common species Increase Low salinity Medium salinity High salinity Change in distribution High phytoplankton biomass Decrease Decrease Climate change effects include higher freshwater flows, which bring more nutrients and sediments into the Bay Large freshwater flow delivering nutrients and sediment. They large herbivores graze on the grasses and weeds for up to seven hours each day, ultimately consuming about 10 – 15% of their body weight. see the adaptations each organism has to survive in this environment.

[4], The fruits are drupelets. Diving species which usually nest on the larger marshes are: canvasback, redhead, ruddy, and lesser scaup. In late summer, long stalks with clusters of individual black, pointed seeds grow from the base of the leaves.
