Invasive Species and the Rivers:  How Students Are Helping Scientists Learn More

Want to learn more about aquatic invasive species and how they impact native species? Are you curious how students are helping scientists uncover the effects these non-natives have on entire ecosystems? Join the National Park Service for an engaging lesson about invasive species in the St. Croix and Namekagon rivers. This free workshop will be held on Saturday, March 6th, from 8:30 a.m. to 12:30 p.m., at the Marshland Center near Grantsburg, Wisconsin.

The workshop will feature presentations by Byron Karns, aquatic biologist for the St. Croix National Scenic Riverway, and Matt Berg, Grantsburg High School science teacher.  

Byron will use a combination of props, visual learning devices, and a PowerPoint presentation to showcase invasive zebra mussels and the threat they pose to rivers. Matt will detail his efforts with high school students and their research on native mussels. Learn what is being done to protect these native mussels from the zebra mussels and other invasive threats. Find out about other dangers looming on the horizon like the Asian carp and Eurasian water milfoil. Discover how your students can become involved in helping researchers learn more. 

This workshop is the fifth in a series of six workshops on the St. Croix National Scenic Riverway being held during the 2009-2010 school year. The workshops are designed to increase awareness of the Riverway as a teaching resource by providing experiences that focus on using the Riverway as a learning laboratory. The series of workshops will also include a presentation and lessons on birds along the Riverway along with a birdwatching field trip.

While the workshops were designed for classroom teachers, all educators at any level are welcome to attend. Educators may attend any or all of the workshops in the series.

Space is limited and registration for the workshop is required. Please call Park Ranger Jean Van Tatenhove (320) 629-2148 to register or for more information. Registration deadline is Thursday, March 4th.  

Final workshop date and topic:  April 17: Birdwatching

The Marshland Center is located at 15975 State Hwy 70, Pine City, Minnesota, on the Minnesota side of the St. Croix River, 5 miles west of Grantsburg, Wisconsin. 

The St. Croix National Scenic Riverway, a unit of the National Park System was established by the Wild and Scenic Rivers Act in 1968; it is one of a group of eight rivers in the country which first received this recognition. For 255 miles, the St. Croix and Namekagon rivers flow through some of the most scenic and least developed country in the Upper Midwest.

Dragonflies spend most of their life living in the water. Eventually they climb out of the water and grab onto something. Here they will emerge from their old skin like a butterfly emerges from its cocoon and fly away.
