ATTENTION! White Nose Syndrome Affecting Bats (Download Poster PDF)
A serious problem is affecting and killing bats in caves in the eastern portion of the United States. Although Crystal Cave tours are not affected at this time, anyone who has been caving in other caves, especially in the eastern U.S. must not wear the same clothing or equipment when visiting Crystal Cave. This will reduce the spread of the problem. For more information please visit the White Nose Syndrome page. More... Crystal Cave.

 
Park worker helps revegetate a site by planting a tree.

Restoration and revegetation is just one way the park fulfills its mission: to preserve and protect park resources.

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.

The Division of Natural Resources strives to:

  • Understand natural processes (such as fire) and human-induced effects on ecosystems (such as effects of air pollution).
  • Mitigate for the existing and potential human effects on ecosystems (for example, restoring previously developed areas using re-vegetation, re-introducing fire to areas where it has been suppressed for decades).
  • Monitor for ongoing or future trends in key ecosystem components.
  • Protect existing natural species, populations, communities, systems, and processes.
  • Interpret these organisms, systems, and processes to park visitors and to visitor center staffs so they may provide current information to the public.

Did You Know?

Sequoia fire scar.

The large black areas at the base of many sequoia trees are fire scars. Even though fire may eat into the very heart of a sequoia tree, the tree can survive so long as the fire doesn't kill the living tissue all the way around the tree. Over time, the fire scars gradually heal over and disappear.
