Sequoia Trees, Redwood National And State Parks, California, United States

Conservation
The entire subfamily is endangered. Sequoiadendron giganteum and Sequoia sempervirens are Vulnerable species, and Metasequoia glyptostroboides is a critically endangered species on the IUCN Red List.
• Introduced range
The two California redwood species, since the early 19th century, and the Chinese redwood species since 1948, have been cultivated horticulturally far beyond their origins. They are found in botanical gardens, public parks, and private landscapes in many similar climates worldwide. Plantings outside their native ranges particularly are found in California, the coastal Northwestern and Eastern United States, areas of China, Germany, and the United Kingdom. They are also used in educational projects recreating the look of the megaflora of the Pleistocene landscape.
