Coastal Redwoods

A Presentation by Amanda Tydings
SOL LS 11 and LS 12

  1. Introduction
    -Redwoods are found on the cost of California and Southern Oregon
    -why they flourish in California and Oregon climate/fog/rainfall
    -why they are called Redwoods
    -less than 10 percent of original Redwood population survives
    -although logged forests have been replanted it will take hundreds of years to replenish
  2. Size and Structure
    -the world's tallest and oldest known tree
    -500-800 yrs. old, 200-240 ft. tall, diameter 10-15 ft.
    -largest Redwood today is 369 ft. tall and has a circumference of 26 ft.
    -Root system shallow 10-13 ft. deep spread out 60-80 ft. when and why they would topple over
    -reproduction, sprouting ability
    -understory species and wildlife
  3. Ecology and Habitats
    -clears the forest floor by burning plants and debris
    -enriches the soil to encourage seed germination
    -destroys fungi and bacteria which could kill seeds
    -enhances forage for wildlife
    -Talk about Native Americans and fire
    -Fire suppression has interrupted natural cycles with negative effects on ecosystems
    -National parks and prescribed burns
    -habitat of Marbled Murrelet
    -Old growth forests and the Spotted Owl
  4. Redwoods Compared to Trees in Virginia
    -American Chestnut and Bald Cypress are very rot resistant like the Redwoods, and these species helped the survival of the Redwoods
    -Compare Redwood with the biggest tree in Virginia
    -tallest measured tree in Va. Sweetgum 151 ft. tall and 17.8 ft. circumference
    -Montgomery County has the largest known Boxelder in the state 60 ft. tall and a circumference of 14.3 ft.
  5. Outside Activity
    -Show kids how age is measured
    -teach kids how to measure DBH and height
