The Mission of the National Park Service is to preserve the resources it protects for future generations to enjoy. To protect these precious natural resources, thirty-two networks were established across the United States to Inventory and Monitor natural resources.

The Upper Columbia Basin Network (UCBN)is composed of nine units managed by the National Park Service located in Idaho, Montana, Oregon, and Washington. These units include:

Big Hole National Battlefield
City of Rocks National Reserve
Craters of the Moon National Monument and Preserve
Hagerman Fossil Beds National Monument 
John Day Fossil Beds National Monument
Lake Roosevelt National Recreation Area Minidoka Internment National Monument
Nez Perce National Historical Park 
Whitman Mission National Historic Site

The UCBN website has copies of reports of all of the parks in the UCBN. These come in a pdf format and can be accessed directly through their website.
