  • 1. By Spencer Gross Sequoia sempervirens
  • 2.
    • The S. sempervirens can grow to be up to 375ft tall (That’s taller than the Statue of Liberty!)
    • S. sempervirens is indigenous in a very small area of the Pacific Northwest
    • The oldest recorded S. sempervirens is 2,200 years old
    • The S. sempervirens can grow up to six feet every year
    Basic Facts
  • 3. To Be or Not to Be? That is The…
    • Why is the S. sempervirens so tall?
    • How does the S. sempervirens transport water to heights of 375 ft?
    • Why is the S. sempervirens indigenous to such a relatively small geographic area?
    • How can a S. sempervirens live 2,200 + years?
    • What is the human impact on the S. sempervirens ?
    • How do baby S. sempervirens manage to grow in the shade caused by mature S. sempervirens ?
  • 4. Why So Tall?
    • As long a tree lives it continues to grow (Long Lifespan = Height)
    • High growth rate (Up to 6ft a year)
    • The S. sempervirens can condense Fog in the summer and make its own rain
  • 5.
    • The Fog that the S. sempervirens depends on for water only occurs in a small area
    • Usually resides between 30-750m above Sea Level
    • This is the 450 mile long and 30 mile wide area of the Pacific Northwest that the S. sempervirens are indigenous to
    • The S. sempervirens used to inhabit the entire Pacific Coast and those of Europe and Asia as well, until the last Ice Age
    Location, Location, Location
  • 6. The Answer is Garlic
    • The S. sempervirens does not go through the process of Senescence
    • When a S. sempervirens dies naturally it is through things such as Fires, F looding, High Winds , etc
    • Old S. sempervirens are somewhat fire retardant because of their thick bark
    • However younger trees are much more susceptible to fire and other forms of death
  • 7.
    • Water that is collected from the roots of the tree must travel 350+ ft against Gravity
    • Since water is polar, water cohesion exists
    • When water evaporates it pulls the water behind it upwards
    • This forms a chain bringing the water from the bottom to the top of the tree

  • 8.
    • … have destroyed 95% of the original Redwood Forest through logging and development
    • … have started forest fires which have destroyed entire new generations of Redwoods
    We The People…
  • 9. It’s Cooler in the Shade
    • Young S. sempervirens are 3 to 4 times more efficient with sunlight than the average tree
    • Only 15% of S. sempervirens seeds are viable
    • Very few S. sempervirens seeds actually start to grow
    • It would take 120,000 S. sempervirens seeds to make 1lb
  • 10. Mutations and Natural Selection
    • Albino Redwoods are S. sempervirens that are unable to make their own Chlorophyll
    • They Survive as Parasites attaching themselves to other Redwoods
    • They can grow up to 60ft in height
