The National Park Service's mission is to
As parks strive to maintain, and in many cases, restore natural processes and ecosystems inside their boundaries, accomplishment of these mandated goals can be comprised by outside activities and actions. Parks do not exist in vacuums, but remain part of, and connected to, the larger landscape that surrounds them. All parks today face threats from invasions of nonnative species, pollution from near and far, and incompatible uses of resources in and around parks.
Great Basin National Park is not immune to these issues. Some of the specific threats facing the park today are groundwater pumping from neighboring valleys that may dry up park springs and springs, proposed coal-fired power plants nearby that may degrade air and water quality, the invasion of cheatgrass to the detriment of many native plant species, and global climate change that could completely alter the plant and animal communities of the Great Basin.
