Nature & Science
The Connecting People to Ecosystems pages provide Information about the natural resources of the Preserve and the scientific research and monitoring that is being conducted to conserve these resources. Each web page has sections containing information, multimedia products, and links to other websites. It is our goal that your visit to these pages will be a virtual visit to the Preserve and that you will come away discovering your own connections to the Yukon Charley Preserve
The National Park Service recognizes that animal, human, and ecosystem health are inextricably linked and viewed holistically. A healthy ecosystem is a place where people, animals, plants, and natural processes interact in ways that support life within an historic range of variability. The living and nonliving components of the ecosystem are often connected in ways that are obscure, or are very complex and unexpected. Science (both western science and local knowledge) is essential in understanding these connections. By focusing research and monitoring on vital resources within an ecosystem, Park biologists and cooperating scientists can provide management with crucial information on current conditions and long-term trends of these vital resources. This will help ensure that the ecosystems are sustained for future generations.
