Flora and fauna
Extreme topographic differences and a striking elevation gradient ranging from 1,360 feet (412 m in the foothills to 14,494 feet 4,417 m along the Sierran crest) create a rich tapestry of environments, from the hot, dry lowlands along the western boundary to the stark and snow-covered alpine high country.
This topographic diversity in turn supports over 1,200 species and more than 1400 taxa, including subspecies and varieties of vascular plants, which make up dozens of unique plant communities. These include not only the renowned groves of massive giant sequoia, but also vast tracts of montane forests, spectacular alpine habitats, and oak woodlands and chaparral.
The richness of the Sierran flora mirrors that of the state as a whole--of the nearly 6,000 species of vascular plants known to occur in California, over 20% of them can be found within Sequoia and Kings Canyon National Parks.
Sequoia and Kings Canyon National Parks support a wide diversity of animal species, reflecting the range in elevation, climate, and habitat variety here. Over 260 native vertebrate species are in the parks; numerous additional species may be present but have not been confirmed. Of the native vertebrates, five species are extirpated extinct here, and over 150 are rare or uncommon.
There have been some studies of invertebrates here, but there is not enough information to know how many species occur in the parks. Many of the parks' caves contain invertebrates, some of which occur only in one cave and are known nowhere else in the world.
History
Humans have traveled or lived in the Southern Sierra for at least 6-7,000 years. In the higher mountains, and also down into the western foothills, lived hunters and gatherers remembered today as the Monache or Western Mono. West of the Monache in the lowest foothills and also across the expanses of the Great Central Valley were a second group, the Yokuts.
In the late 1700s and early 1800s, Spanish began exploring the edge of the Sierras. Soon afterwards, trappers, sheepherders, miners, and loggers poured into the Sierras seeking to exploit whatever the mountains had to offer. By the end of the 19th century, San Joaquin Valley communities increasingly looked to the Sierras for water and recreation. In the struggle between all these competing interests, two national parks were born that became what we know today as Sequoia and Kings Canyon National Parks. Today the parks together protect 265 Native American archeological sites and 69 historic sites.
Understand
Although technically they are two separate national parks, Sequoia and Kings Canyon generally operate as a single unit in many ways. One fee US $5 per person or US $20 per private vehicle allows entrance to both parks.
The combined area of these two parks is 865,952 acres 3,504 km² with most of that area being wilderness backcountry. The altitiude in the parks range from 1,300 feet 418m to 14,505 ft 4421 m. The front country area can be divided into basic areas: The Foothills, Giant Forest, Mineral King, Grant Grove, and Kings Canyon and Cedar Grove.
