Tree: A Life Story (or Tree: A Biography in Australia) is a Canadian non-fiction book written by David Suzuki and Wayne Grady, and illustrated by Robert Bateman. The book profiles the life of a Douglas-fir tree, from seed to maturity to death. The story provides ecological context by describing interactions with other lifeforms in the forest ...
Trees play a significant role in reducing erosion and moderating the climate. They remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues. Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world.

David Douglas (25 June 1799 – 12 July 1834) was a Scottish botanist, best known as the namesake of the Douglas fir.

The Chinese dictionary-encyclopaedia Erh Ya probably dates from about 300 BC and describes about 334 plants classed as trees or shrubs, each with a common name and illustration. The Han Dynasty (202 BC-220 AD) includes the notable work of the Huangdi Neijing and the famous pharmacologist Zhang Zhongjing .
The dominant tree groups today are all seed plants, the gymnosperms, which include the coniferous trees, and the angiosperms, which contain all fruiting and flowering trees. No free-sporing trees like Archaeopteris exist in the extant flora. It was long thought that the angiosperms arose from within the gymnosperms, but recent molecular ...
Peattie's nature writings are distinguished by a poetic and philosophical cast of mind and are scientifically scrupulous. His best known works are the two books (out of a planned trilogy) on North American trees, A Natural History of Trees of Eastern and Central North America (1950) and A Natural History of Western Trees (1953), with woodcut illustrations by Paul Landacre.
Theophrastus's Enquiry into Plants or Historia Plantarum (Ancient Greek: Περὶ φυτῶν ἱστορία, Peri phyton historia) was, along with his mentor Aristotle's History of Animals, Pliny the Elder's Natural History and Dioscorides's De materia medica, one of the most important books of natural history written in ancient times, and like them it was influential in the Renaissance.
Most of these plants have true roots and leaves, and many were quite tall. The tree-like Archaeopteris, ancestral to the gymnosperms, and the giant cladoxylopsid trees had true wood. These are the oldest known trees of the world's first forests. Prototaxites was the fruiting body of an enormous fungus that stood more than 8 meters tall. By the ...
