2020 Kayak/Canoe Field Seminar and Classroom Lecture Series:

An Introduction to Aquatic Plants

with Gerould Wilhelm and Laura Rericha


Classroom Lecture: July 18th, 2020

Field Seminar: July 25th and July 26th, 2020


Conservation Research Institute is announcing an intense field workshop for the summer of 2020. Wilhelm and Rericha will take a deep dive into the ecology and taxonomy of plants floating or rooted in healthy, floristically diverse waters of the Chicago Region.


Each student will learn how to recognize aquatic plants and how to use a dichotomous key. Students also will learn how to prepare specimens.

Field Seminar: "Prairies of the Chicago Region" Class of 2017

Saturday, July 18 – Introductory Classroom Lecture

There will be a 4-hour lecture on the morphology and ecology of aquatic plants. A laminated fascicle of keys and descriptions, distilled from the Flora of the Chicago Region: A Floristic and Ecological Synthesis, will be provided.


Saturday, July 25th and Sunday July 26th – Field Work

The following weekend, over two days, we will visit four magnificent lakes in Indiana, Michigan, and Wisconsin. Each lake teems with such genera as Brasenia, Dulichium, Pontederia, Potamogeton, Najas, Ceratophyllum, Elodea, Schoenoplectus, Scirpus, and dozens of other aquatic species to which few people have access and with which few botanists have taxonomic training. Each student will need to bring a kayak or canoe to study the lakes.

There is room for a maximum of 20 students in the classroom lecture and 15 students for the field seminar. The cost is $1,800 dollars, half of which is paid up front to secure a position in the class. The

remaining balance must be paid by June 1st, 2020. The cost to students who wish take advantage of the

lecture only is $400.00; the laminated wetland plant guide is included with the lecture. No refunds

will be remitted after that date.

Speaking Engagements


Gerould Wilhelm, PhD, is available for speaking engagements through Conservation Research Institute (CRI). Jerry is an internationally renowned botanist and ecologist who has been studying the Chicago region flora for over 40-years. He is coauthor, with Laura Rericha, of Flora of the Chicago Region: A Floristic and Ecological Synthesis, published by the Indiana Academy of Science in 2017.

Dr. Wilhelm has been requested to speak to many groups over the past several decades, from professional botanical societies, to workshops and seminars, conservation groups, and local garden clubs. Topics close to his heart are listed below, but presentation topics can be tailored to a specific request. The base fee-stipend for a speaking engagement is $1000, necessary to compensate Jerry for preparation, presentation, and travel (for locations within a 25-mile radius from Glen Ellyn, Illinois). Speaking engagements are approximately 2 to 3 hours in length.*


• Floristic Quality Assessment and Species Conservatism

• The Ecology and Culture of Water

• Biblical Environmental Wisdom

School of Athens Painting by Raphael

• Consilience

• Other topics have included: The Dune Flora; History of Botany in Chicago Region


Book Signings: Jerry and Laura are available for book signings for the Flora, which can include a brief 35 minute presentation.*

Flora of the Chicago Region: A Floristic and Ecological Synthesis by Gerould Wilhelm and Laura Rericha (2017)

Completely updated and rewritten, the Flora of the Chicago Region: A Floristic and Ecological Synthesis is rich with new and expanded features in comparison with the 4th edition of the Plants of the Chicago Region by Floyd Swink and Gerould Wilhelm (1994). Also, it has added newly-described species and range updates; morphological descriptions; taxonomic etymology; re-evaluations of many problematic genera; an entirely new section of associate flora and fauna such as bryophytes, lichens, insects, birds, and mammals; in-depth descriptions of our region’s habitats, geology, and soils; a re-evaluation of our region's coefficients of conservatism, and original illustrations for every genus. For more information, click here.

The Flora is available for purchase from the Indiana Academy of Science and the Morton Arboretum bookstore in Lisle, Illinois.

Root Systems of Prairie Plants Poster This much loved illustration by Heidi Natura displays the deep root systems of our natural grasslands and all that implies about the importance of rainwater infiltration and soil organic production. CRI owns the copyright for this image.

Ongoing Research



Research at Conservation Research Institute is ongoing. Currently, our researchers are in need of support to pursue the completion of floristic and faunistic works on the lichens, bees, ants, and ongoing work with the vascular plants. Donors will be acknowledged in
upcoming publications.
