Sequoia Sempervirens

  1. 1. By Spencer Gross Sequoia sempervirens
  2. 2. <ul><li>The S. sempervirens can grow to be up to 375ft tall (That’s taller than the Statue of Liberty!) </li></ul><ul><li>S. sempervirens is indigenous in a very small area of the Pacific Northwest </li></ul><ul><li>The oldest recorded S. sempervirens is 2,200 years old </li></ul><ul><li>The S. sempervirens can grow up to six feet every year </li></ul>Basic Facts
  3. 3. To Be or Not to Be? That is The… <ul><li>Why is the S. sempervirens so tall? </li></ul><ul><li>How does the S. sempervirens transport water to heights of 375 ft? </li></ul><ul><li>Why is the S. sempervirens indigenous to such a relatively small geographic area? </li></ul><ul><li>How can a S. sempervirens live 2,200 + years? </li></ul><ul><li>What is the human impact on the S. sempervirens ? </li></ul><ul><li>How do baby S. sempervirens manage to grow in the shade caused by mature S. sempervirens ? </li></ul>
  4. 4. Why So Tall? <ul><li>As long a tree lives it continues to grow (Long Lifespan = Height) </li></ul><ul><li>High growth rate (Up to 6ft a year) </li></ul><ul><li>The S. sempervirens can condense Fog in the summer and make its own rain </li></ul>
  5. 5. <ul><li>The Fog that the S. sempervirens depends on for water only occurs in a small area </li></ul><ul><li>Usually resides between 30-750m above Sea Level </li></ul><ul><li>This is the 450 mile long and 30 mile wide area of the Pacific Northwest that the S. sempervirens are indigenous to </li></ul><ul><li>The S. sempervirens used to inhabit the entire Pacific Coast and those of Europe and Asia as well, until the last Ice Age </li></ul>Location, Location, Location
  6. 6. The Answer is Garlic <ul><li>The S. sempervirens does not go through the process of Senescence </li></ul><ul><li>When a S. sempervirens dies naturally it is through things such as Fires, F looding, High Winds , etc </li></ul><ul><li>Old S. sempervirens are somewhat fire retardant because of their thick bark </li></ul><ul><li>However younger trees are much more susceptible to fire and other forms of death </li></ul>
  7. 7. <ul><li>Water that is collected from the roots of the tree must travel 350+ ft against Gravity </li></ul><ul><li>Since water is polar, water cohesion exists </li></ul><ul><li>When water evaporates it pulls the water behind it upwards </li></ul><ul><li>This forms a chain bringing the water from the bottom to the top of the tree </li></ul>H 2 O
  8. 8. <ul><li>… have destroyed 95% of the original Redwood Forest through logging and development </li></ul><ul><li>… have started forest fires which have destroyed entire new generations of Redwoods </li></ul>We The People…
  9. 9. It’s Cooler in the Shade <ul><li>Young S. sempervirens are 3 to 4 times more efficient with sunlight than the average tree </li></ul><ul><li>Only 15% of S. sempervirens seeds are viable </li></ul><ul><li>Very few S. sempervirens seeds actually start to grow </li></ul><ul><li>It would take 120,000 S. sempervirens seeds to make 1lb </li></ul>
  10. 10. Mutations and Natural Selection <ul><li>Albino Redwoods are S. sempervirens that are unable to make their own Chlorophyll </li></ul><ul><li>They Survive as Parasites attaching themselves to other Redwoods </li></ul><ul><li>They can grow up to 60ft in height </li></ul>
