Summary

Since 1916, the National Park Service has worked to preserve our country’s natural and cultural resources for current and future generations. U.S. National Parks inspire more than 318 million visitors per year, and these unimpaired landscapes provide safe refuge to more than 600 at-risk species. Unfortunately, they also provide safe refuge to some highly unwelcome wildlife.
