The most common vegetation for more than 90 percent of the land on the island is desert scrub of many different species. The lower elevations, especially the south, receive very sparse rainfall. However, the northern and western parts of the island are often shrouded in fog, and some plants have adapted to receiving moisture from fog. The fog plus the slightly greater rainfall at higher elevations has permitted the existence of Monterey pine forests at elevations of to where the influence of the fog is most intense. The pine forests are scattered and only cover 0.46 percent of the total area of the island. The pines grow to a height of up to . California juniper are also found at similar altitudes, covering 0.05 percent of the land area.
