Welcome to the natural resources webpages for Sequoia and Kings Canyon National Parks. Here you will find descriptions of natural resources in these two parks, as well as introductions to different components of the Science and Natural Resources Management program (SNRM). Links are provided above to other webpages on various aspects of the SNRM program: air resources, geology, vegetation, water, wildlife, and inventory & monitoring. They provide more information about park resources and management, along with species lists, reports, and links to related sites.
Sequoia and Kings Canyon National Parks contain big trees, high peaks, and deep canyons, but the diversity goes far beyond that. Located in the southern Sierra Nevada range, the parks' elevations extend from 1,300 feet (418m) in the foothills to 14,491 feet (4,417m) at the summit of Mount Whitney, the highest mountain in the contiguous 48 states. Plunging in the opposite direction far below the surface are over 200 marble caverns, many with endemic cave fauna. This huge variation in the landscape contributes to the collage of habitats that create a rich assemblage of terrestrial, aquatic and subterranean ecosystems. Here one can observe a vast diversity of plants and animals representing an array of adaptations.
Despite the protected status of resources within park boundaries, many threats to park resources exist. These include air pollutants, invasion by alien species, loss of natural fire regimes, habitat fragmentation, and rapid human-caused climatic change.
