Abies magnifica, also known as the California Red Fir or Red Fir, is an evergreen tree that grows well in heavy clay soils. It requires a cool position in a good moist but not water-logged soil. It is very shade tolerant, especially when young, but growth may be slower in dense shade. The tree prefers growing on a north-facing slope. This large tree can grow up to 120-180 ft m tall and 6 ft trunk diameter, and is typically found in the mountains of southwest Oregon and California in the United States. The Red Fir is a high elevation tree, usually found at elevations between 4,500-9,000 feet, though it rarely reaches tree line. The bark of old trees gives the tree its name, as it becomes a beautiful orange-red color. Red Fir is an important forest tree and its wood is used for general structural purposes, paper manufacture, and it is also a popular Christmas tree. Its high-quality young Silvertip Firs, with dense dark-green needles, sell for top prices as Christmas trees. The Red Fir dominates large areas of high country, which are a major source of water, especially in California. This makes the Red Fir a significant tree for those interested in preserving the environment and ecology of natural forests.
