YELLOWSTONE NATIONAL PARK, Mont. (AP) — Yellowstone National Park is has hired three Mandarin-speaking rangers to help with communication amid a growing number of Chinese tourists.

The Billings Gazette reports that Yellowstone South District Resource Education Ranger Rich Jehle says basic safety publications are available in many languages, but it's different to have a ranger who can talk directly with a visitor. Yellowstone doesn't track visitation by nation of origin and is relying instead on a perceived increase.

The new hires are interpretive rangers who provide about the parks. According to U.S. Department of Commerce statistics, Chinese visitation to the U.S. increased by 451 percent between 2007 and 2015. The Idaho Falls newspaper recently reported that the city is also seeing an influx of Chinese visitors on their way to and from Yellowstone.
