spoken by Mark Arnold

We wanted our sidewalks to call attention to the fact that the cave and the surface are not separate worlds but part of one unique ecosystem. We developed sidewalk blocks with pictures etched in them of cave animals and plants that are native to this region. Places where caves are found are called karst regions. Karst regions typically have limestone substrates with very thin soil layers. Certain types of plants grow better in karst regions, such as trout lilies and cedar trees. Here you see an engraving of Eggert’s sunflower, a species that was on the endangered species list from 1997 to 2005. Randy Seymour, co-owner of Roundstone Native Seeds in Hart County, explains that before the prairies of central Kentucky were plowed up for farming, these small sunflowers grew on the slopes and ridges bordering the prairies and were a source of food for birds. Today they are too rare to make much of a contribution to food for wildlife.
