Redwood (Sequoia)

Redwood-SRedwoods are really cool trees. They are huge—the tallest and biggest trees in the world. It’s amazing that trees so big grow from seeds that are so tiny—100,000 of them would only weigh a pound. Their cones are small, too; they’re no bigger than an inch.

Two types of redwoods live in the United States, the coast redwood and the giant sequoia, and both need our help. Habitat loss due to development and logging continue to threaten redwood forests. The changing climate, with noticeably less fog along the Pacific coast, and increased air pollution in California’s Central Valley and Sierras are also impacting these magnificent trees.


Coast redwoods are native along the Pacific coast, from southern Oregon to central California. Giant sequoias remain only in a few areas within the western Sierra Nevada Mountains.


Coast redwoods need the moist cool air of the Pacific coast to grow, while giant sequoias prefer dry, sunny areas and require forest fires to help open their cones and clear out competing plants.
