"Indigenous tribes are leading the effort to bring back the bison — a victory not only for the sake of biodiversity, but for the entire ecosystem they nurture".
"Miles of prairie stretched out across the Wichita Mountains Wildlife Refuge in southern Oklahoma, acre after acre of brush, grasses and hearty vegetation creeping toward the low-range granite mountains rising in the distance. Like in much of Oklahoma, the road is flat here, but the speed limit remains 30 mph. That’s because of the bison.
They appeared seemingly out of nowhere: dozens of massive animals lumbering up the shoulder of the road to cross to the fresh vegetation on the other side. The herd moved slowly, their soft, bovine eyes barely registering the stopped cars awaiting their passage. They quickly set to work mowing down the fresh springtime grass.
The bison’s quiet munching does more than nourish their bodies — it’s one of many things they do to nurture their entire ecosystem, one that is increasingly under threat from climate change. Grazing bison shaving down acres of vegetation leave more than dung behind: Their aggressive chewing spurs growth of nutritious new plant shoots, and their natural behaviors — the microhabitats they create by rolling in the ground, the many birds that forged symbiotic relationships with them — trickle down the food chain. Once bordering on extinction, bison now serve as a great provider for their ecosystems, standing as an example of the ways in which animal conservation and ecological protection can work in tandem."
