- There are approximately 100,00 known species of trees in the world. There are also estimated to be thousands of undiscovered species in rainforests and other uninhabited parts of the world.
- Trees are the largest plant.
- Trees, like all plants, capture the energy of sunlight and through the process of photosynthesis. During photosynthesis plants and trees convert the sun’s energy into chemical energy, which they use for their own growth and life processes.
- This energy is passed on, supporting a large community of living things. Many animals eat the fruits, seeds, leaves, sap, or even the wood of trees. On the forest floor, the fallen leaves decompose, thus supporting microorganisms, mushrooms, worms, insects, and other plants and animals. A layer of soil is built up and protected by the trees’ roots. Besides food, trees also provide many species of animals with habitat, nesting space, and protection from predators.
- Trees also help to modify the climate. They provide shade in hot weather and shelter from the wind. In some places, they help to cause more rainfall and condensation of fog. The forest floor holds water from rain and snow, helping to lessen the effects of flooding and drought. Trees can also hold snowfall in place to prevent avalanches and mudslide and slow the spring melt.
- From the beginning , trees have provided people with food, in the form of fruits and nuts, and wood for fires, tools, and shelters. Trees also shade homes and act as windbreaks to protect homes, and they help prevent soil erosion.
- Many useful products come from trees, including some medicines, rubber, cork, turpentine, tannic acid which is used for curing leather.
- Trees are grouped into two basis categories. Deciduous trees are also called “broadleaf”. The maple, oak, elm, hickory, aspen and birch are all examples of deciduous trees, The other type of tree is the evergreen. Cypress, eucalyptus, and pine are examples of the evergreen.
- Most deciduous trees lose their leaves in the fall and begin a cycle of growth in the spring. Evergreen trees remain green for most of the year and they are continuously losing and growing the needles or leaves.
- Largest trees are the Giant Sequoia.
