Introduction

Prairies are plant communities dominated by the grasses. However, they also preserve a large diversity of wildflowers, butterflies, and birds. The flowering season begins in early spring, sometimes before the last snowfall, and doesn't end until killing frosts of late autumn. These characteristics make prairies and savannas favorite destinations for hikers, birders, and wildflower enthusiasts.
