Q:
WHAT ARE COAST REDWOODS? |
| A: Coast
Redwoods are the tallest tree species and among the largest living
organisms ever to inhabit the Earth. Redwoods are named for the beautiful
red color of their bark and heartwood. The wood has a high level of
tannic acid, which is toxic to most insect pests. |

|
| Q:
WHERE ARE COAST REDWOODS FOUND? |
| A: Coast
Redwood forests are found only along the Pacific Ocean from central
California to southern Oregon in a narrow zone about 20 miles wide
and 450 miles long. More than tall trees, a Redwood forest is a complex
ecosystem made up of an astounding variety of living and once living
things. Today they are an endangered
species. |

| Q:
HOW TALL DO COAST REDWOODS GET? |
| A: Mature
coast redwood trees average 200 feet tall, but often they reach more
than 300 feet in height. More than a dozen trees over 360 feet tall
live along the coast of California. |
| |
| Q:
HOW OLD ARE THEY? |
| A: Individual
coast redwood trees can live for hundreds of years. In some areas
of their range, they can live more than two thousand years. The oldest
recorded coast redwood is 2,200 years old. |
| |
| Q:
HOW DO REDWOODS REPRODUCE? |
| A: Redwoods
are conifers, which means they have cones and needle-like leaves.
A redwood cone is about one inch long and contains 14 to 24 tiny seeds
about the size of a tomato seed. A single tree may produce millions
of seeds in a year. Only a small percentage of the seeds actually
germinate and grow into seedlings. Although redwoods can grow from
seeds, they more commonly reproduce from sprouts. New trees can sprout
from the roots of parent trees, from buds at the base of a tree, or
from a fallen tree. If a tree is cut or burned, a circle of trees
may sprout from the stump, forming a "fairy ring" of new
trees. |

| Q:
WHERE HAVE REDWOOD FOSSILS BEEN FOUND? |
| A: Redwood
trees are true "living fossils," having existed largely
unchanged for millions of years. Redwood fossils as old as 160 million
years have been found throughout the western United States and Canada
and along the coasts of Europe and Asia. Close ancestors of the coast
redwood have been living since dinosaurs first appeared. Coast redwoods
prefer mild year-round temperatures with winter rain and heavy fog,
a climate that was more common in earlier ages. The last ice age limited
coast redwoods to their present range. |

| Q:
ARE THERE OTHER KINDS OF REDWOODS? |
| A: There
are three different redwood species: "The coast redwood"
(Sequoia sempervirens) is the world's tallest tree species. It grows
in forests only along the west coast of California and southern Oregon.
It is evergreen. "The giant sequoia" (Sequoiadendron giganteum)
is shorter - up to 300 feet - but larger in diameter than the coast
redwood. It is the world's largest (most massive in total weight)
tree species. It grows only at 4,000 to 8,000-foot elevations in California's
Sierra Nevada. It is also evergreen. "The dawn redwood"
(Metasequoia glyptostroboides) is much shorter than the other two
redwoods, up to 100 feet tall. Scientists thought that this species
was extinct until it was discovered growing in a remote area of China.
It is deciduous (not evergreen) in winter. |
