The “Place in Between”, “The Big Empty”, “Flyover Country” - it goes by many bleak names, but North America’s iconic sagebrush steppe is far more than the forgotten backdrop of a Hollywood western - it is the planet’s only home for a deceptively subtle ecosystem: a vast wilderness spanning 250,000 square miles which, at second glance, is brimming with hardy life. But despite its size, this veritable sea of sagebrush is a fragmented landscape with a tenuous future. As we begin to leave our mark here, wringing profit from the land, the marks of other lives more ancient - the cascading songs of sage thrashers, the otherworldly booming of strutting grouse, or the widely-spaced tracks of a Pronghorn’s sprint - are at risk of fading away.
