View our plant photo catalog featuring over 100 photos of wetland plants found in Minnesota shallow lakes and North Dakota prairie pothole wetlands.
In the video, you can see Chara spp., Utricularia vulgaris, Lemna trisulca, and Potamogeton zosteriformis. I made this video while doing field work for my graduate research project on shallow lakes in Minnesota. We used a Plexiglass-bottomed cylinder to view submerged aquatic vegetation from a canoe.
For more information on the design of the submerged vegetation viewer see our article: Macrophytes in shallow lakes: Relationships with water, sediment and watershed characteristics
An invasive species in Williams Pond
An invasive species in Williams Pond
We have been monitoring the aquatic vegetation in and around Williams Pond at George Washington Carver Monument near Diamond, Missouri since 2017. Williams pond is a spring-fed pond at this National Park.
A few years ago Potamogeton crispus (curly leaf pondweed) was observed growing in Williams pond. P. crispus prefers cooler waters, usually peaks in the spring, and dies back in the summer. This plant is an invasive species and its prolific growth is a problem in many states. However, its growth has not been a problem in Williams pond. On July 26, 2019 we observed P. crispus spreading throughout the pond, which is unusual for this time of year. We will continue to monitor its growth throughout the year.
Emergents at Williams Pond
Emergents at Williams Pond
We have been monitoring the aquatic vegetation in and around Williams Pond at George Washington Carver Monument, near Diamond, Missouri since 2017. Williams pond is a spring-fed pond at this National Park.
In the fall of 2018, we found possibly three different species of Persicaria growing along the water's edge. Looking forward to seeing how these plants spread and colonize the shoreline.
Update: After a survey on July 26, 2019 we found new Persicaria growth along the banks (north, east, and west) and in shallow water near the spring box.

In summer 2017 we sampled gravel bar vegetation in Big River in SE Missouri. Big River is located in Missouri's Old Lead Belt, which has experienced lead mining pollution for centuries.

Former students, Christine Cornish and Chet Hall scoping out golf course ponds to sample in Neosho, MO.
Christine and Chet conducted aquatic vegetation surveys, completed water quality measurements, and collected sediment samples for analysis.
