Mahogany furniture is popular among the people. Tropical rainforest plants, including redwood, can regulate the global climate and maintain the ecosystem. Excessive cutting of redwood can damage the habitat of many living things and cause soil erosion. It is reported that the redwoods have been cut down worldwide, and the United Nations has explicitly protected tropical rainforest plants, including redwoods, and prohibits deforestation. In the UK, there are more laws that stipulate that buying and selling mahogany furniture is illegal because redwood is a protected species.
The growth rings of the redwood species grow in the form of concentric circles and generate an annual ring every year. We can learn about the climate and natural environment that affect their growth by observing the annual rings of the redwood species, and explore the growth environment of the redwood species.
The cross-sections of the redwood species present a concentric circle of varying numbers and irregularities, namely the annual rings. The wheel structure of these annual rings changes with the climate. Like the redwood tree species growing in the tropical rain forest, enjoying the environment of watery feet and high temperature, the cell division speed is relatively fast, the cell wall is thin, the shape is larger, the material is softer, the material color is lighter, and the formed wheel structure is wider, called early The redwood grown in the temperate and frigid autumn or tropical dry season lacks the water carrier for transporting nutrients, so the nutrient flow of the tree is slow, the activity of the layered cells is gradually weakened, the cell division speed is slowed and gradually stops. The cell cavity is small and the wall is thick, the material color is deep, the tissue is dense, and the formed wheel structure is relatively narrow, which is called the late material band.
In a growing season, from the early transition of the early wood to the late wood, a complete wheel structure, the annual ring, appears on the cross section of the wood. Early wood and late wood directly affect the natural texture changes and chromatic aberration of the red wood. It can be seen that the majestic texture and warm color of the mahogany is the crystallization of nature.

Redwood growth depends on specific heights and special soils. Redwoods are generally grown in tropical jungles or swamps ranging from 200 to 1200 meters in height, and are prone to rapid growth and foliage in deep, moist, and fertile soil. Northern California has a lot of rainfall, the seasons are spring and sunny, so the pleasant climate is very suitable for the growth of redwood. The growth period of redwood is extremely slow, and it grows 3 centimeters thick every 100 years. The folks have the saying of “Millennium Rosewood, a hundred years of sour branchesâ€, and their products often need hundreds or even thousands of years. The growth cycle of redwood is longer than other trees, and it is not afraid of fire. It is a veritable rare tree species.
