Pronunciation: [ʃˈastə fˈɜː] (IPA) 
The correct spelling of the tree species known as "Shasta fir" is /ˈʃæstə fɜr/. The word "Shasta" refers to the region in Northern California where this type of fir tree is commonly found. Meanwhile, "fir" denotes the species of tree Shasta fir belongs to. Its phonetic transcription, /ˈʃæstə fɜr/, represents the sounds of "sh" as in "shoe", "a" as in "cat", "s" as in "sit", "t" as in "top", and "f" as in "fire".
Shasta fir, scientifically known as Abies magnifica var. shastensis, is a coniferous evergreen tree belonging to the family Pinaceae. It is a distinct variety of the California red fir species (Abies magnifica) and is native to the forests of the Klamath Mountains, specifically the slopes of Mount Shasta in northern California, United States.
The Shasta fir is characterized by its tall stature, reaching heights of up to 180 feet (55 meters) with a trunk diameter of about 6 feet (2 meters). It displays a slender, spire-like shape and a dense, symmetrical crown. The bark is smooth and gray when young, gradually becoming brown and fissured as the tree matures.
The Shasta fir features short, flat, and glossy dark green needles that spiral around the branches in a spiral whorl formation. These needles, which are about 1.5 inches (4 centimeters) long, give the tree its distinct appearance. It bears cylindrical cones that grow upright on the branches and disintegrate upon maturity, releasing their seeds.
Due to its aesthetic qualities and attractive form, the Shasta fir is highly sought after as an ornamental tree in gardens and parks. Its timber is also utilized in construction and furniture making. However, its limited range and susceptibility to climatic changes, diseases, and pests have led to concerns over its conservation status. Efforts are being made to protect and preserve the Shasta fir through sustainable forestry practices and habitat conservation initiatives.
The word "Shasta fir" is derived from the combination of two separate words: "Shasta" and "fir".
The term "Shasta" refers to Mount Shasta, a stratovolcano located in Northern California, United States. Mount Shasta is well-known for its lush coniferous forests, including the species of fir trees found in the region.
On the other hand, "fir" is a common term used to describe a genus (Abies) of evergreen coniferous trees. Firs are known for their needle-like leaves, upright cones, and ability to grow in various habitats worldwide.
Therefore, "Shasta fir" refers to the type of fir tree species found in the Mount Shasta area. The etymology essentially combines the geographical reference to Mount Shasta with the generic term for fir trees.
