Redwood Forest

Sequoia sempervirens

Sequoia sempervirens, the coast redwood, is the sole living species of the genus Sequoia in the cypress family, Cupressaceae. Other common names include coastal redwood and California redwood. It is a coniferous, long-lived, monoecious tree that has reached ages of about 2,000 years. The species has produced the tallest living trees on Earth, reaching up to 116.22 m (381.3 ft) in height and up to 8.9 m (29 ft) in diameter at breast height. These trees are also among the longest-living trees on Earth.

Sequoioideae

Sequoioideae, commonly referred to as redwoods, is a subfamily of coniferous trees within the family Cupressaceae that range in the northern hemisphere. It includes the largest and tallest trees in the world. The trees in the subfamily are amongst the most distinctive trees in the world and are common ornamental trees. The subfamily reached its peak of diversity during the early Cenozoic. They are fast-growing trees that live in temperate climates such as Mediterranean and humid subtropical climates. Three living species are known, the coast redwood, the giant redwood and the dawn redwood. While the coast redwood and the giant redwood are found in the western United States, the dawn redwood is known from China.

Forest

A forest is an ecosystem characterized by a dense community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ. It does not include land that is predominantly under agricultural or urban use." Using this definition, Global Forest Resources Assessment 2025 found that forests covered 4.14 billion hectares, or approximately 31 percent of the world's land area in 2025.

Shades of red

Varieties of the color red may differ in hue, chroma, lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
