The message
Human stewardship has shaped biodiversity for millennia and continues to do so.
The experience
A backlit case contains a geometric mosaic of colors and textures. On closer examination, the mosaic is composed of seeds from Chicago area prairies. Handheld magnifying glasses let visitors explore the wide range of forms, including dense spikes, delicate fluff, slender gold grains, and blood-red pearls.
Opposite this display is an unlikely set of conservation tools: A drip-can, lighter, flame-retardant jumpsuit, face shield, and heavy, insulated gloves. The installation might permit visitors to try on a piece of burn gear. Dramatic footage of a prairie burn accompanies these objects.
The display illustrates the aspects of prairie plants that make them so well-suited to fire—unlike their invasive neighbors. This includes a low growth point, deep root systems, dry leaves that act as accelerant, and seedpods that respond to fire.
The story
The native people of what is today Chicago originally burned prairies to create more robust ecosystems. There is a complex relationship between the shaping of this landscape by both lightening and man-made fires, and the evolution of prairie plants. Their contemporary structure is suited to and in some cases dependent on fire. Ongoing human stewardship helps these species maintain their habitat against encroaching invasive plants and fragmentation.
Few Chicagoans realize their region includes rare ecosystems. Seed processing efforts include a strong citizen science component, providing an opportunity for local visitors to move from awareness to action.
