 Typical of mountains closest to the Pacific in California, these trees ignore the elevation separations of vegetation (known as life zones) that are found on many other mountains.For example, in the adjacent picture, trees such as White Fir and Incense Cedar, are seen growing on the lowest extent of the mountain beside dryer, weather-tolerant trees such as Jeffrey Pine and Ponderosa Pine.In winter, the weather on Toro Peak and the Santa Rosa Mountains can be difficult.
