Zooxanthellae require a mixture of white and blue light to thrive within the coral, depending on the coral type. [11] Some corals, like the orange cup coral, do not require light, and rely on the plankton or free-floating nutrients as sustenance. [12] Coral reefs protect the coastline from erosion and storm damage.
The reserve is a 32-acre (0.13 km 2) holding which extends from Montara light station at the north to Pillar Point on the south. The reserve consists of a three-mile stretch of beach, tidepool habitat, marsh, erosive bluffs, clifftop trail and cypress and eucalyptus forests.

The California State Parks system alone has 270 units and covers 1.3 million acres (5,300 km 2), with over 280 miles (450 km) of coastline, 625 miles (1,006 km) of lake and river frontage, nearly 18,000 campsites, and 3,000 miles (5,000 km) of hiking, biking, and equestrian trails.
Metal halide bulbs come in a variety of spectra from 5000k on up to 20,000k and allow for a variety of light-hungry corals to survive under them. Many aquarists will use metal halide bulbs in conjunction with either power compact fluorescents or T5 fluorescents since halide lighting does not have the overall balanced effect of other light types.
Coral reefs also support a huge community of life, including the corals themselves, their symbiotic zooxanthellae, tropical fish and many other organisms. Much attention in marine biology is focused on coral reefs and the El Niño weather phenomenon. In 1998, coral reefs experienced the most severe mass bleaching events on record, when vast ...

Coral reefs are some of the most biodiverse habitats on earth, supporting large numbers of species of corals, fish, molluscs, worms, arthropods, starfish, sea urchins, other invertebrates and algae. Because of the photosynthetic requirements of the corals, they are found in shallow waters, and many of these fringe land masses. [24]
Crystal Lake in Angeles National Forest, Azusa, California. Photo taken in July 1998 after a rainy season following a period of El Niño..
