Eighteen national forests in California make up the national forest lands of the Pacific Southwestern Region of the U.S. Forest Service. Much of the Region is within the California floristic province, unique in the United States for its Mediterranean climate of dry, hot summers and wet or snowy winters. Many wildflowers of the California national forests grow nowhere else in the world. From ancient rock gardens to sagebrush steppes to squishy mountain fens, California's native plants are spectacular!
