Facts about Redwood Trees
- 11
Sequoia sempervirens trees produce a tannin-rich bark up to 12 inches thick that resists fire, insects, and decay better than any other tree species on Earth.
- 10
Approximately 90 percent of a coast redwood's nutrient intake comes from fog drip rather than soil absorption, a unique adaptation to coastal California's summer drought conditions.
- 09
Redwood tree roots typically extend only 6 to 12 feet deep but spread laterally up to 100 feet, interlocking with neighboring trees for stability in coastal storms.
- 08
Over 95 percent of old-growth coast redwood forests have been logged since the 1850s, reducing the original 2 million acres to approximately 5 percent remaining today.
- 07
Giant sequoias, the largest redwood species by volume, can grow to 2,700 years old with trunk diameters exceeding 25 feet at their base.
- 06
Redwood trees lack growth rings in their bark, making it impossible to determine their age by counting rings like other tree species.
- 05
Coast redwood trees in Northern California produce enough oxygen annually to sustain approximately 2,000 people for one year.
- 04
Redwood trees can weigh up to 2 million pounds and store enough water in their bark to survive year-round droughts.
- 03
Coast redwoods can live for over 2,200 years, with the oldest known specimen, Alamo, estimated at approximately 2,520 years old.
- 02
Coast redwoods can absorb up to 1,000 gallons of water daily through their bark and foliage during coastal fog events.
- 01
The tallest tree on Earth, Hyperion, a coast redwood in California, reaches 380.1 feet in height.
