3. Redwood Habitat
Redwoods used to be abundant, but
now live mostly on the coasts of
California. Forests are foggy and
moist. Less than 5% of the redwoods
alive are old-growth redwoods. This
means have grown for a very long
time and are mature, adult trees.

4. Redwoods that are old-growth compared to young
trees.

5. Reproduction
Trees reproduce, although their reproduction
process is very different from that of animals. The
Redwood's reproduction process is similar to that
of most other conifers. They begin to make seeds
at 10-15 years of age. Only 15% of those seeds are
viable. They are very small, and approximately
8,500 seeds make up an ounce. Seedling grow so
fast that 20 year old trees are often over 65 feet tall!
