Yellowstone National Park has just published its latest issue of Yellowstone Science magazine, the park’s periodical devoted to natural and cultural resources, focuses in this issue on a suite of ecological indicators that measure the health of the Greater Yellowstone Ecosystem.Guest Editor Andrew Ray explains that not unlike doctors who measure vital signs to track human health, scientists study ecological indicators to understand and measure the health of plants, animals, ecosystems, parks, and even the Earth itself. Since 2008, the park and the network have released four vital signs reports that provide snapshots about the status of each vital sign monitored in Yellowstone. Appearing a decade after the first report, this issue of Yellowstone Science provides an in-depth look at what scientists have learned about some of these vital signs over that period. Yellowstone Superintendent Cam Sholly explains that the park’s ability to understand and respond to threats like climate change and visitor impacts is heavily dependent on quality data and science.
