Coast redwood

Coast redwood range from southern Oregon to central California, extending not more than fifty miles inland only as far as the coastal climate has its influence. Fog plays an important role in the survival of trees, protecting them from the summer drought conditions typical of this area. They also need abundant winter rains and moderate temperatures year round. In ideal conditions a coast redwood can grow 2-3 feet high every year, but when trees stressed from lack of moisture and sunlight they can grow as little as one inch per year.

Because this tree is so tall, needle Treetop exposed to dry heat over a needle branches in dense canopy below. To compensate for this, redwood needles grow Treetop with tight spikes of conserving water, because surface vaporize a bit. The branches are lower, on the other hand, produces flat needles to capture additional light through the thick canopy of branches.

These trees have shallow root systems that extend more than a hundred yards from the bottom, entwined with the roots of other redwoods. This increases their stability during high winds and flooding.

Redwood is naturally resistant to insects, fungi, and fire because of their high tannin and do not produce resin or pitch. Their thick, reddish, pithy skin also provides protection and insulation for the tree. Even took a tree to survive this blackened hollows you'll see when you walk through the grove was caused by fires in 1926, and is evidence of extraordinary ability trees' survival.

Redwood trees flower in the months of wet and rainy December and January. They produce cones that matured in the autumn. Redwood cone about an inch long and they produce small seeds, about the same size as the tomato seeds. While each tree can produce 100,000 seeds per year, very low germination rates. Most redwood sprouts grow more successful than that formed around the base of the tree, taking advantage of the nutrients and tree root systems mature. When the parent tree dies, a new generation rose tree, creating a circle of trees is often called fairy rings.
