North America was once a loose, sprawling conversation between landscapes. During a dry spell, lightning might spark a fire that burned for miles and days on end, relenting only when it hit a lake or river. Remove fire, and this dialogue gets interrupted. “Ruderal junk — that’s what happens without fire,” said Bill Kleiman, project director at Nachusa Grasslands, a 3,600-acre preserve operated by @nature_org in Illinois. Bill’s team runs controlled burns every spring and fall. For thousands of years, indigenous Americans ignited the landscape to bring bison and deer to hunt, and berries and tubers to harvest. European colonizers took these strategies, but a few catastrophic wildfires in the early 20th century helped convince land managers that fire should be vanquished. Eventually, cologists suspected fire suppression was disrupting natural life cycles. In the 1960s, scientists encouraged policymakers to allow for natural processes like fire. Last spring, the photographer @_lyndonfrench_ caught a glimpse of a controlled burn at Nachusa — and the life that sprung up a few weeks later. Swipe left to see some of his photos.
