Last Stand of the Tallgrass Prairie

Where's the tall grass?

Tallgrass prairie once covered 170 million acres of North America. Within a generation the vast majority was developed and plowed under. Today less than 4% remains, mostly here in the Kansas Flint Hills. The preserve protects a nationally significant remnant of the once vast tallgrass prairie and its cultural resources. Here the tallgrass prairie takes its last stand.

Southwind Nature Trail at Tallgrass Prairie National Preserve

A single blade of big bluestem might have a root system descending over 8 feet underground. This is deep enough so that the plant will emerge in the spring even without rainfall. Big bluestem grows abundantly on the Southwind Nature Trail.
