Closed-cone pine forest

Closed-cone pine forest is a plant community of coastal California
and several offshore islands. It consists of stands of Bishop Pine

regions along the coast with cool wet winters and foggy, dry summers. Despite the fact that the summers are dry, the air is consistently humid due to frequent coastal fog brought in by interior heat. The fog also supplies irrigation when it passes through the conifer needles of the pines. The moisture is caught this way and drips to the forest floor. Thus, drought is avoided by up to 40%. In the autumn fog is less frequent and it is during this season when occasional heat waves are possible. This is when fires are most likely. Precipitation ranges from 20 to 60 inches a year, depending on the locale.
