The range and population numbers of lesser prairie-chickens have declined dramatically due conversion of grassland habitat to cropland, energy development, urban development, woody plant encroachment, fire suppression, and unsustainable grazing. In 2017, a range-wide survey estimated their population at roughly 33,000. Their numbers are most precarious in the sand-shinnery oak eco-region of the southern Great Plains, where Sand Ranch is located. In this photo, a lesser prairie-chicken male conducts his mating display at a lek site in Kansas that burned in a prescribed fire just three days earlier.
