Sequoiadendron giganteum

Sequoiadendron giganteum, also known as the giant sequoia, giant redwood or Sierra redwood is a coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the most massive trees on Earth. They occur naturally only in groves on the western slopes of the Sierra Nevada mountain range of California.

The giant sequoia is listed as an endangered species by the IUCN, with fewer than 80,000 trees remaining. Since its last assessment as an endangered species in 2011, it was estimated that another 13–19% of the population was destroyed during the Castle Fire of 2020 and the KNP Complex & Windy Fire in 2021, events attributed to fire suppression and drought. Prescribed burns to reduce available fuel load may be crucial for saving the species.The Giant sequoia grow to an average height of 50–85 m with trunk diameters ranging from 6–8 m.
