LOESS HILLS PRAIRIE SEMINAR

May 31st - June 2nd, 2019

Getting people; getting children acquainted with what's out here will make people concerned about what is happening here. If we get acquainted with natural communities we feel at home. Any place we feel at home, we feel like protecting.

The Loess Hills Seminar began in 1977 with a group of approximately 25 people who wanted to study the unique characteristics of this special area. To get an accurate feeling of the “Hills,” and preserve the delicate ecology the group backpacked into the interior for the first seminar. Since then the increased number of participants has necessitated a more convenient location. The original idea of preserving the “back to nature” concept of the seminar however, is still a major goal of the organizers.

The Loess Hills are a geological formation created thousands of years ago during the glacial periods. The Missouri River Valley flooded every summer with the ice melt from these glaciers. During the cool months, however, the flows declined, creating expansive mud flats. Winds dried and picked up this soil causing huge dust storms. Much of the wind-blown soil or loess was dropped near the mud flats in “dirt drifts” exceeding 200 feet in depth.

There are several reasons why the Loess Hills are unique. The soil itself is composed of “silt-sized” particles. This allows water to rapidly pass, which creates an arid or dry condition. South- and west-facing slopes of the Hills are baked in sunlight, while slopes facing north and east are more shaded. These shaded slopes are often wooded with relatively young stands of Bur Oak.

The sunny, steep slopes have remained in native grasses and flowers, genetically tied to the same vegetation that was here before settlers arrived. The combination and quality of both timber and prairie make this ideal for study.

Weekend Activities:

This seminar was developed to serve students of all ages, families, professionals in the conservation field, and all community members. Each year we see families come back. It has grown to be a multi-generational event.
