California is a state of enormous diversity. From the coast to the mountains and the forests to the deserts, California is full of a wide array of plant life. California is the third largest state in the United States and thus has a major variation in climate resulting in the many plants found. Not only are there many plants found here, but many of those plants cannot be found anywhere else. There are also many nonnative plants that have become a part of the scenery in California. The best way to understand the state’s vegetation is to first understand the floristic provinces.
In North America there are 12 floristic provinces with four of those found in California (Map #1). California itself has five major biomes, some of which can be

Redwood trees are located in the California floristic province. It covers the cismontane region of California as well as part of southwestern Oregon. The climate there is Mediterranean dry hot summers and wet, cool winters. The tree at RSABG was around 1300 years old. During the time that this tree was standing the American Civil War was taking place because of the spread of slavery. The vernal pools (Picture #4) are a part of the grasslands and marshes biome. Most of the pools are found in the central valley but also in the inland valleys of the inner Coast Ranges, and along coastal terraces of Southern California. They are temporary pools of water that are usually without fish, and thus allow the safe development of natal amphibian and insect species. Most pools are dry for at least part of the year and fill with the winter rains or snow melt. Some pools may remain at least partially filled with water over the course of a year or more, but all vernal pools dry up periodically. They are called vernal pools because they are often at their deepest in the spring. Despite being dry at times, once filled they are full of life. The most obvious inhabitants are various species of frogs and toads. Manzanitas (Picture #5) are evergreen shrubs or small trees present in the chaparral biome. They are characterized by smooth, orange or red bark and stiff, twisting branches. There are 106 species of Manzanita, 95 of which are found in California.
