The significance of Channel Islands National Park stems from the islands’ remote, isolated position at the confluence of two major ocean currents, a region of persistent oceanic upwelling, and the border of two tectonic plates. The park contains examples of two biogeographical provinces in the ocean, the Oregonian and the Californian, and a dynamic transition zone between them. In a remarkably small area, the park harbors the biologic diversity of nearly 1,000 miles of the West Coast of North America. In addition to this diversity, park waters are also exceptionally productive. Swirling around the islands, cool, nutrient-rich oceanic waters rise into abundant sunlight and mix with warm coastal waters, accelerating photosynthesis and growth rates of myriad forms of sea life from microscopic plankton to blue whales.

The park preserves some of the finest remnants of the coastal Mediterranean-type ecosystem in America. The most endangered in the world, this type of ecosystem is found in only five places. The unique suite of plants and animals that have colonized the islands and their isolation over eons has resulted in the evolution of many endemic species and subspecies. The park also harbors a prolific paleontological record; archeological resources that record nearly 13,000 years of continuous human occupation; and historical features that represent ranching, fishing, hunting, navigation, and other endeavors from a wide variety of cultures.

The Channel Islands National Park provides the public with unparalleled opportunities for solitude, tranquility, wildlife viewing, and appreciation of natural history, outdoor recreation, and education.
