Reflections on water | 31 août 2007

A tree is a large perennial woody plant, larger than a shrub and for sure more importante than a BUSH . It is sometimes defined as a woody plant that attains diameter of 10 cm (30 cm girth) or more at breast height (130 cm above ground). However, there is no set agreement regarding minimum size, the term generally applies to plants that grow to at least 5-6 meters (15-20 ft) high at maturity and having secondary branches supported on a main stem or stems, called a trunk. Most trees exhibit clear apical dominance, though this is not always the case. Compared with most other plants, trees are long-lived, some of them getting to be several thousand years old and growing to up to 115 meters (375 ft) high.

Trees are an important component of the natural landscape due to their prevention of erosion and the provision of a specific weather-sheltered ecosystem in and under their foliage. Trees have also been found to play an important role in producing oxygen and reducing carbon dioxide in the atmosphere, as well as moderating ground temperatures. They are also significant elements in landscaping and agriculture, both for their aesthetic appeal and their orchard crops (such as apples). Wood from trees is a common building material. Trees also play an intimate role in many of the world's mythologies
