Gowen cypress (Cupressus goveniana)

Also known as the dwarf cypress and Santa Cruz cypress, fewer than 2,300 individual Gowen cypress trees are found in just five counties in California: Mendocino, Sonoma, Santa Cruz, San Mateo and Monterey, according to the IUCN, which lists the tree as endangered.

These trees are usually around 30 feet tall but can grow much taller if conditions are right. The U.S. Forest Service says the population is declining due to rodents and deer eating seedlings, livestock grazing on them and trampling them, and a fungus called coryneum canker, which kills the tree and spreads from tree to tree through the distribution of spores.
