The massive Grizzly Giant sequoia tree stands with a wide, reddish-brown trunk and a hollowed base, surrounded by other tall trees in Mariposa Grove, Yosemite National Park. — Conifer A giant sequoia (*Sequoiadendron giganteum*) estimated to be between 1,900 and 2,400 years old, Grizzly Giant is the oldest tree in the Mariposa Grove, Yosemite National Park, California.

Tropical conifers are often found in cooler mountain areas because these higher elevations provide the temperate conditions to which many conifer species are adapted, contrasting with the perpetually hot climates of lowland tropical regions.12

In the wet tropics, temperatures decrease by approximately 0.5 °C (0.9 °F) for every 100 meters of elevation gained. While most tropical rainforests are characterized by consistently high temperatures, the cooler, higher-altitude zones allow for the growth of conifers that thrive in temperate environments. Consequently, these mountain areas serve as a refuge where conifers can form solid stands or grow alongside tropical hardwoods, whereas only a few specific species are adapted to the heat of lower elevations.21
