What Are Redwood Trees?

How Tall Are Redwood Trees?
Giant redwood trees grow between 165 and 360 ft. (50 – 110 m) tall. The tallest recorded redwood tree is a California redwood that is 379.7 (115.7 m) tall. From the three redwood species, the coast redwood (California redwood) is the tallest, the giant sequoia in second place, and the dawn redwood is the smallest at around 165 ft. (50 m) tall.
Types of Redwood Trees
Let’s look briefly at the three species of trees in the Sequoioideae subfamily:
Sequoia vs. Redwood
Trees in the family Sequoioideae are typically all referred to as redwoods. Even though redwood trees and sequoia trees are closely related, they have some distinguishable characteristics. Here are the four significant differences between sequoias (Sequoiadendron giganteum) and redwoods (Sequoia sempervirens):
Redwood Tree leaves
Redwood trees have variable leaves depending if they grow at the upper canopy or lower down the tree. At the crown, evergreen redwood needles grow up to 0.4” (1 cm) long, are pointed, narrow, and oblong, and grow spirally like cedar or juniper leaves. Redwood leaves growing on lower branches are flattened and longer.
Redwood Tree Bark
The cinnamon-red or bright reddish-brown bark is one way to identify redwood trees. A redwood tree has recognizable spongy bark and is a dull chocolatey brown color. Giant sequoias are identified by their fibrous bark that is a brighter red-brown color. You can also tell redwood trees because the reddish bark pulls away easily.
Redwood Tree Flowers
Redwood trees produce small, insignificant yellowish-brown flowers that blossom on the ends of needle leaves. Redwood flowers blossom in December and January. However, it isn’t easy to see the flowers from the ground because they are so tiny and far up in the forest canopy.
How do soils help the environment?

What is the role of soil carbon storage in forests?
Forest soil carbon storage can be a significant reservoir for sequestering atmospheric carbon dioxide. Redwood forests rely on rapid nutrient cycling of minerals in the topsoil and abundant rainfall and fog for their astounding growth but subsoils are generally highly weathered and low in nutrients.
Is floodplain soil more fertile than ridgetop soil?
These soils are moderately weathered and are more fertile than ridgetop soils. Nutrient rich floodplain soils are like a cake, soil is built in layers over time.
