Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology , the study of climate and atmospheric conditions during different periods in history from the wood of old trees.
This means that the tree you pick out at your local lot this year has been growing for nearly a decade! As the tree matures, it begins to grow faster. As the tree matures, it begins to grow faster.
Time-lapse of a flower opening. Plumeria trees flower from early summer to fall. Their blossoms grow in clusters on ends of the stems, they are made of tubular corolla with a length of 2–4 inches (5.1–10.2 cm) that split sharply into five rounded and waxy petals that overlap each other.
The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995.. A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.
The Oyashio Current and strong winds affect summer temperatures to prevent tree growth. The Aleutian Islands are almost completely treeless. Alaska, United States 152°W: 68°N Trees grow north to the south-facing slopes of the Brooks Range. The mountains block cold air coming off of the Arctic Ocean. Northwest Territories, Canada 132°W: 69°N

Trees with very large girths, such as some of the sequoias growing the western United States, can also pose girth measurement problems. If they are growing on even a gentle slope, if girth is measured at 4.5 feet about where the pith of the tree emerges from the ground, the upside of the tape could easily be below ground level.
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 end of the Devonian, the first seed-forming plants had appeared. This rapid appearance of so many plant groups and growth forms has been called the "Devonian Explosion".
