What is ancient tree?
An ancient tree is one that has passed beyond maturity and is old, or aged, in comparison with other trees of the same species. Its canopy may be small. It will probably have a very wide trunk relative to other trees of the same species and it is very likely that it will be hollow.
What is another word for dead tree?
Snags - The name for dead trees that are left upright to decompose naturally. Logs - When a snag (or part of a snag) falls on the ground, it becomes a log—also very useful for wildlife habitat.
What is considered a mature tree?
Mature tree means a living tree with a circumference of thirty or more inches, including all major stems, as measured four and one-half feet above the roof crown (9.5 inch diameter).
How old is an old tree?
Trees can live anywhere from less than 100 years to more than a few thousand years depending on the species. However, one species in particular outlives them all. The Great Basin Bristlecone Pine (Pinus longaeva) has been deemed the oldest tree in existence, reaching an age of over 5,000 years old.
How would you describe a dead tree?
Dead Tree means a tree is lifeless. Such evidence of lifelessness may include unseasonable lack of foliage, brittle dry branches, or lack of any growth during the growing season.
What is a dead forest called?
Ghost forests are areas of dead trees in former forests, typically in coastal regions where rising sea levels or tectonic shifts have altered the height of a land mass.

How old is a birch tree?
A birch tree could be considered as ancient at 150 years old, for example, but an oak tree would not be thought of as ancient until it’s at least 400 years old. Yew trees can live for thousands of years, so are not defined as ancient until they are 800 years old.
What is a tree in botanical terms?
A new layer of wood is added in each growing season, thickening the stem, existing branches and roots. Although "tree" is a term of common parlance, there is no universally recognised precise definition of what a tree is, either botanically or in common language. In its broadest sense, a tree is any plant with the general form of an elongated stem, ...
What is a tree?
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species . In some usages, the definition of a tree may be narrower, including only wood plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, ...
How many species of gymnosperm trees are there?
The majority of tree species are angiosperms. There are about 1000 species of gymnosperm trees, including conifers, cycads, ginkgophytes and gnetales; they produce seeds which are not enclosed in fruits, but in open structures such as pine cones, and many have tough waxy leaves, such as pine needles.
Why do trees have a second spurt of growth?
In some tree species in temperate climates, a second spurt of growth, a Lammas growth may occur which is believed to be a strategy to compensate for loss of early foliage to insect predators. Primary growth is the elongation of the stems and roots.
How do trees reproduce?
Trees usually reproduce using seeds. Flowers and fruit may be present, but some trees, such as conifers, instead have pollen cones and seed cones. Palms, bananas, and bamboos also produce seeds, but tree ferns produce spores instead. Trees play a significant role in reducing erosion and moderating the climate.
What is the layer of bark that protects trees?
For most trees it is surrounded by a layer of bark which serves as a protective barrier. Below the ground, the roots branch and spread out widely; they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the branches divide into smaller branches and shoots.
Why do trees pop out of the soil?
Some tree species have developed root extensions that pop out of soil, in order to get oxygen, when it is not available in the soil because of excess water.
The Riddle of the 100 Year-Old Tree
Let us imagine that God creates a fully grown tree today, and places it in a forest. A week later, a scientist and a theologian encounter this tree. The theologian believes that God is trustworthy and has clearly communicated to him that this tree was created just a week ago. The scientist bores a hole in the tree, and counts its rings.
An Analogy to Evolution
In context, the parable is rooted in the strong evidence for common ancestry of humans and chimpanzees. Many Christians disagree and believe that humans were specially created. Maybe they are right. Let us, for a moment, leave the scientific debate aside, to look at the much more interesting theological question.

Summary
Overview
The tree growth habit is an evolutionary adaptation found in different groups of plants: by growing taller, trees are able to compete better for sunlight. Trees tend to be tall and long-lived, some reaching several thousand years old. Several trees are among the oldest organisms now living. Trees have modified structures such as thicker stems composed of specialised cells that add struc…
Definition
Although "tree" is a term of common parlance, there is no universally recognised precise definition of what a tree is, either botanically or in common language. In its broadest sense, a tree is any plant with the general form of an elongated stem, or trunk, which supports the photosynthetic leaves or branches at some distance above the ground. Trees are also typically defined by height, with sm…
Distribution
The number of trees in the world, according to a 2015 estimate, is 3.04 trillion, of which 1.39 trillion (46%) are in the tropics or sub-tropics, 0.61 trillion (20%) in the temperate zones, and 0.74 trillion (24%) in the coniferous boreal forests. The estimate is about eight times higher than previous estimates, and is based on tree densities measured on over 400,000 plots. It remains subject to a wide m…
Parts and function
The roots of a tree serve to anchor it to the ground and gather water and nutrients to transfer to all parts of the tree. They are also used for reproduction, defence, survival, energy storage and many other purposes. The radicle or embryonic root is the first part of a seedling to emerge from the seed during the process of germination. This develops into a taproot which goes straight down…
Evolutionary history
The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period. The first tree may have been Wattieza, fossils of which have been found in New York State in 2007 dating back to the Middle Devonian (about 385 million years ago). Prior to this discovery, Archaeopteris was the earliest known tree. Both of these reproduced by spores rather than s…
Ecology
Trees are an important part of the terrestrial ecosystem, providing essential habitats including many kinds of forest for communities of organisms. Epiphytic plants such as ferns, some mosses, liverworts, orchids and some species of parasitic plants (e.g., mistletoe) hang from branches; these along with arboreal lichens, algae, and fungi provide micro-habitats for themselves and for other organisms, including animals. Leaves, flowers and fruits are seasonally available. On the groun…
Uses
Trees are the source of many of the world's best known fleshy fruits. Apples, pears, plums, cherries and citrus are all grown commercially in temperate climates and a wide range of edible fruits are found in the tropics. Other commercially important fruit include dates, figs and olives. Palm oil is obtained from the fruits of the oil palm (Elaeis guineensis). The fruits of the cocoa tree (Theobroma …
