Trees provide nuts and different fruits for human consumption, contribute oxygen and play a role in water conservation.

What to know about trees?

I’m sure you know the basic stuff:

  • Trees produce oxygen, which we need to breathe
  • They absorb carbon dioxide, helping us fight climate change
  • They produce timber, firewood and paper
  • They provide a habitat for wildlife

What do trees do for the environment?

Trees benefit the environment. Trees absorb carbon dioxide as they grow and the carbon that they store in their wood helps slow the rate of global warming. They reduce wind speeds and cool the air as they lose moisture and reflect heat upwards from their leaves. It’s estimated that trees can reduce the temperature in a city by up to 7°C.

How do trees help each other?

Trees support one another by sharing nutrients, and also support a complex variety of other organisms, especially fungi. The complex networks that allow trees to communicate among themselves and with other organisms, has led some to use the term " Wood Wide Web " by analogy to the World Wide Web that creates the Internet. The idea is that trees are constantly communicating with one another and with other organisms to benefit themselves, and perhaps to help their progeny. Although there is some good science behind this, it is easy to jump to conclusions. There is no evidence that trees are sentient, or aware of people, or that they make decisions in some intelligent way.

How do trees respond to their environment?

Trees do have immense powers, and the ability to rapidly respond to changes in their environment. They adjust rapidly to subtle changes in their environment that we would scarcely notice , such as the quick passing of a shadow over a leaf, or minute changes in the angle of a branch. They respond to their enemies - insects, fungi, bacteria, or herbivores - with complex and quick changes in their chemistry. Of the trees that we consume - cocoa or coffee or bourbon (oak extract) - most of the flavor comes from compounds that the trees create to defend themselves. Trees send and receive chemical signals, either through the air or the roots, not only to other trees but to many other organisms, especially insects.

Do trees have a central nervous system?

It is easy to anthropomorphize a tree, to force our human framework upon them and make them into ents or some other mystical creature. Yet trees are not at all like animals. They don't have a central nervous system or a brain, they don't have muscles, and they can't move.

Do trees have senses?

Their sensory abilities often exceed ours. A slight touch of your finger against a leaf on a calm day can quickly cause a wide variety of changes in the chemistry and growth of a plant. Trees also have senses that we lack. They can instantly detect changes in gravity, so that bending a branch produces a rapid growth response. They can see parts of the electromagnetic spectrum, such as infrared and ultraviolet, that we cannot.

Buds can be helpful in identifying tree species in winter, when deciduous trees are without foliage. Those at the end of a twig are called terminal buds , while those growing along the twig are lateral buds. The arrangement of these lateral buds can help establish a tree’s identity. Alternate buds, found on elms, are arranged in alternating pairs on opposite sides of the stem. The opposite buds of maple are directly facing each other on the stem. And spiral buds whorl alternately around the stem, as seen on oaks.

How to identify a tree with flowers?

While there’s a whole class known as flowering trees (everything from crabapples to magnolias), other tree species have inconspicuous flowers. Either way, flowers can help with identification. First, consider the color (although this isn’t a fail-safe method, since plant breeders have expanded the color palette in the cultivars they have developed). More helpful is to consider when the flower appears and what it looks like. Flower types include single blooms, clustered blooms or catkins (pictured), which are dense hanging spikes that look like tassels. Many trees bloom in spring, but some flower in summer or even early fall, helping you eliminate certain tree species as you investigate.

What color does a maple tree go?

Leaf Identification Type. The starting point for most people when identifying trees species is the leaves. There are three basic leaf types: needles, scales and broadleaf.
