Koyama spruce
Picea koyamae Shiras.
Picea koyamae is a critically endangered spruce species native to the Akaishi and Yatsugatake Mountains in central Honshu, Japan. It is an evergreen tree that can reach up to 25 m in height with a trunk diameter of up to 1 m. The species is found in small, isolated stands and occupies an area of less than 100 square kilometers. Due to its limited range and vulnerability to typhoon damage, it is at high risk of extinction in the wild. Some individuals are cultivated for ornamental purposes.

The tree is known for its limited area of occupancy and is threatened by natural disasters such as typhoons, which often replace lost trees with faster-growing species.
