Therkildsen Field Station at Emiquon

Therkildsen Field Station at Emiquon The station promotes river floodplain research, on-site/online learning, and outreach; it has an ope and Barbara Cordwell Therkildsen Field Station at Emiquon.

In order to study, research, and document this unique, immense experiment, UIS established the Alfred O. The Therkildsen Field Station is a scientific facility near the towns of Lewiston and Havana, IL, about 45 miles northwest from Springfield on the Illinois River. . Elements that make Therkildsen a unique facility include:

Its location and cooperation with the Conservancy will make the Therkil

dsen Field Station the premier scientific facility associated with the Emiquon restoration. The Therkildsen Field Station offers both on-site and on-line learning. Therkildsen supports UIS student & faculty research, and it will work in conjunction with the Conservancy’s staff and other collaborating scientists. Therkildsen has developed a collection documenting species diversity and change - both at the traditional (specimen) level and at the molecular (meta-genomic) level.

We still have dates available for fall field trips! High school teachers, schedule Marvelous Macroinvertebrates, a fantastic hands-on experience for your students.

Through three main activities—sampling, sorting, and examining samples—students will learn how to identify aquatic macroinvertebrates and how these creatures can be used as indicators of the health of wetlands and other aquatic systems. Students will learn to collect macroinvertebrate samples in the wetland using a D-net and then, examine and identify their samples in the lab utilizing a microscope.

We are seeking applicants for fall, winter, and spring projects! Be sure to visit our website for details on how to submit a proposal.

We are welcoming artists working in any genre (including but not limited to painting, photography, sculpture, ceramics, handwork, music, dance, creative writing) to apply for our Artist-in-Residence Program (AIR). The program aims to forge a connection between the science of the floodplain restoration and artistic perspective of the Emiquon Preserve. Our goal is to build a community of artists and to provide space for them to create unique interpretive works of art.

TFSE’s AIR program is an award for up to a four-week experience at the station throughout the year. Currently, applications are being accepted on a rolling basis. Funding is now available for projects through Spring 2027 from the UIS Visionary Giving Circle.

TFSE has been home this summer for graduate researcher, Alexa Rojas, from the University of Illinois Urbana Champaign, and her two field technicians Hannah and Tijona, who are surveying various wooded areas in the Central Illinois River Valley for moth caterpillars to determine the impact of spray drift on the area's moth population. This is the second year working on this project.

Of the experience Rojas shares:

After our first field season looking at how caterpillar numbers compare in different agricultural settings, we found that in all forests we surveyed, caterpillars were more abundant the deeper we traveled into a forest. The difference in abundance between habitat edges and interiors became starker when the landscape was more surrounded by corn and soybean fields. We are at the tail end of our second and last field season now, so we will find out if that pattern holds true after a second season of data later this year after we run final analyses. Many different factors could be behind this pattern, but one interesting potential cause could be that pesticide drift impacts habitat suitability for caterpillars, since important host plants like oaks have been shown to suffer injury from common agricultural herbicides. Direct exposure to pesticides could also be a factor, especially from insecticides and fungicides, which are likely to be more deadly when insects are exposed to them.

The busiest season is now ramping up and we're finding up to 105 caterpillars in a night!

It's estimated that there are over 1,800 species of moths, members of the insect Order Lepidoptera, in Illinois. Moths pollinate flowers and are a food source for birds and mammals. A decline in moth populations can adversely affect the ecosystem.

Our recent Artist-in-Residence, Basia Krol, shared the following about her experience at the Emiquon Preserve:

A simple walk in nature is not simple anymore, not just for city dwellers or suburbanites but even for farmers. To walk in a forest is to walk through second—or third-growth riddled with rosa multiflora, and to walk the prairie, we now have to reconstruct it.

It gives me hope when humans reconstruct and give our fragile systems the care they deserve. We protect and cherish what we have amid the abundance of loss. Inspired by indigenous and restored natural habitat, my art explores the intersection of ecology and spirituality.

The restored floodplain of the Illinois River that forms the Emiquon Preserve is a perfect place for me. My stay there was full of magical moments and hours of uninterrupted reflection. I would wake up before down and run all the way to Thompson Lake to watch the sunrise. I can never achieve in my paintings the beauty of it but I will try to paint how the beauty felt.

I was fascinated by the lotus fields and the pelicans. Suddenly my mid-western state of Illinois became this wondrous tropical land. So many birds, dragonflies, frogs, giant fish, minks and muskrats and deer are everywhere and yet so elusive! How to paint them..?

I also found myself constantly wanting more. I wanted to be immersed, to get closer to animals, to wade up the stream till I was lost in the ridge, to follow tiniest deer paths through the prairies, to swim and float in the lakes, to get closer to pelicans and egrets and herons! Swimming was off limits but I spent some of the best hours of my life in the kayak, the Station let me borrow. I was surprised by the conflicting needs of belonging to and owning nature. I recognize this struggle as a very human struggle. It is hard for us to love nature and let it be. It must have something to do with our perception of being an outsider, a consciousness separated from the system, observing everything from our position in the center of the universe.

My joy, my struggles, hikes and adventures created an emotional footprint for many paintings to come. The best way to share Emiquon is beyond words.

Basia's artwork will be on display at Projects Unveiled on Sunday, August 23, from 1-4 p.m., at the field station, 11316 N. Prairie Road, Lewistown. The paintings will be among several artists' original pieces inspired by the Emiquon Preserve debuted at the event. Projects Unveiled is free and open to the public. Please dress appropriately for the weather as part of the program may be held outdoors.

The AIR is funded by the Visionary Giving Circle and partially supported by a grant from the Illinois Arts Council Agency and local funds from the Two Rivers Arts Council.
