America’s national parks saw more than 331 million visits last year, a record. But the Trump administration does not want to call attention to those numbers, according to a National Park Service memo, amid mass firings of rangers and other employees at the Grand Canyon, Yosemite, Arches and other popular destinations.

The internal memo, issued Wednesday, said the agency would “not issue a press release or other proactive communications, including social media posts” regarding the numbers. Individual parks could make public visitor numbers if directly asked for them, it said. The data also was posted online.
