You may not realize it, but you're on the edge of something exciting! Look around and you will see that three of the park's ecosystems meet at this very spot. Where ecosystems meet is called an edge. This edge is exciting becasue it has characteristics of the forest, prairie and riparian areas, making it very diverse. Forest animals, such as deer and elk, feed along the edges during dawn and dusk then return to the shelter of the forest during the day. Edges provide both food and shelter, which is why you will often see more wildlife in these areas.

Edges are constantly changing. As the trees drop pine cones onto the prairie, seedlings begin to grow. When fire sweeps across the land it burns the young seedlings, reclaiming land for the prairie. In years between fires, seedlings again flourish. This cycle has occurred throughout history under natural conditions. As you hike look for signs of the fire cycle. Also, think about why many animals prefer to live "life on the edge."
