Abies magnifica shastensis (Shasta Red Fir)

Abies magnifica shastensis (Shasta Red Fir) is a subspecies or ecotype of the California Red Fir (Abies magnifica) that is specifically found in the Shasta region of California, United States. 

The Shasta Red Fir shares many characteristics with the California Red Fir. It is a large evergreen coniferous tree with a tall and stately appearance. The tree can reach heights of up to 60 meters (197 feet) and has a straight trunk with a diameter of about 1 to 2 meters (3 to 6.5 feet). The bark of the Shasta Red Fir is typically grayish-brown and becomes rough and furrowed with age. 

Like the California Red Fir, the Shasta Red Fir features dense, dark green needles that are arranged in a spiral pattern along the branches. The needles are relatively long, ranging from 2 to 4 centimeters (0.8 to 1.6 inches), and have a soft texture. They give the tree an elegant and vibrant appearance. 

During spring, the Shasta Red Fir produces small, upright cones that grow toward the top of the tree. These cones start out green and mature into brown or purplish-brown. Each cone contains seeds that are released and dispersed by the wind. 

The Shasta Red Fir, as a variety of Abies magnifica, shares similar growth requirements and environmental preferences. It is typically found in montane and subalpine forests at higher elevations. The tree thrives in well-drained soils and prefers full sun to partial shade. 

The Shasta Red Fir, specifically adapted to the Shasta region, plays a significant ecological role by providing habitat and food for various bird species, mammals, and insects. It contributes to the biodiversity and ecosystem balance of the local environment. 

In summary, the Shasta Red Fir (Abies magnifica shastensis) is a subspecies or ecotype of the California Red Fir (Abies magnifica) that is specifically found in the Shasta region of California. It shares many characteristics with the California Red Fir, including its large size, dense dark green foliage, and cone production. The Shasta Red Fir is an important component of the local ecosystem and adds beauty to the natural landscapes of the region.
