National park and marine reserve
San Miguel, Santa Rosa, Santa Cruz, Anacapa, and Santa Barbara together make up the Channel Islands National Park , to which tourist access is restricted.
The Channel Islands are home to the island gray fox , an endemic species of fox that is one of the smallest fox species in the world. This species developed from the North American gray fox and is a typical form of island dwarfing . About 30,000 to 12,000 years ago, another example of island dwarfing lived on the Channel Islands of California, the dwarf mammoth ( Mammuthus exilis ), an extinct species from the family Elephants with a shoulder height of 1.20 to 1.80 meters.
The surrounding seas are also protected and form the " National Marine Sanctuary of the Channel Islands" ( Channel Islands National Marine Sanctuary ). It is one of the most biodiverse marine areas in the world. The large kelp forests are home to over 1000 different species. In addition to seaweed , these include various types of plankton , mussels , crabs , sea slugs , seahorses , wrasse , perch , rays , sharks , sea urchins , octopuses , starfish , anemones and sponges . This biodiversity makes the Channel Islands National Marine Sanctuary a prime location for cold water dives.
The abundance of fish in the area favors the occurrence of large whales as well as the colonies of the four seal species Northern elephant seal , California sea lion , Steller sea lion and Northern fur seal .
history
The earliest human settlement has been dated between 13,000 and 11,300 Before Present (defined as "before 1950"). From here a further settlement of the central Andes started about 4,200 years ago.
