A tree is a large plant with a single woody trunk that branches off at a certain height from the ground..
The plant will be considered a tree if, already at maturity, its height, exceeds 6 meters high and also produces secondary branches year after year, differing by these conditions from the bushes. On the other hand, longevity turns out to be another characteristic of this type of plantFor example, some species, such as the California giant sequoias, which can exceed 100 m in height and more than six thousand tons in weight.
Tree parts and varieties
The trees are attached to the ground by a group of roots that join the aforementioned woody trunk, while the bark, which acts as a protection, will become smoother as one advances in height and on the side of the branches that compose it, the same ones, will always be in the same place, although, with time they will become thicker.
During the Spring season, sprigs, leaves and in some cases even flowers sprout from the buds.
As mentioned above, each year trees add a new layer of growth to their trunk and branches, if the trunk is cut we will find rings that will not only allow us to know the age of the tree, but also by analyzing the thickness of the We ourselves will be able to know how much it has grown during the year.
There are different types of trees, leafy (with wide and flat leaves, they produce flowers and are typical of warmer areas, such as oak, beech and maples), conifers (characteristic of the cool areas, they have hard and thin leaves and mostly produce pineapples) and the tropicalPalm trees being the most characteristic and popular of this type (they need to live from the heat and the rains).
But beyond the varieties there are structures in the trees that are repeated, such is the case of the root, which is the component that allows the tree to nourish itself; the trunk that provides the wood and that is the hardest part that maintains the top of the tree; the branches arising from the trunk are thinned once they reach the ends; and leaves that play a very important role in attracting sunlight to carry out the photosynthesis process.
Fundamental in terms of balancing the environment and the development of the economy
Trees, moreover, turn out to be a predominant and very necessary part of any ecosystem, since they not only help prevent erosion, but also dress landscapes, form jungles and forests; and they are also essential at the behest of the development of various industries as a result of the wood that is extracted from them and which turns out to be a fundamental raw material in the field of construction and design of wooden furniture, for example.
They are also very important for the paper industry since cellulose from trees is used to make this important material that is so widely used in various contexts.
The economic exploitation of trees is by no means new, but dates from the most remote times when precisely the tremendous utility that could be given to the raw materials obtained from them was discovered.
So, trees are very important for the economic activity of any nation and for keeping the natural environment in which they are inserted balanced.
Reforestation to preserve and regenerate species
As a consequence of the above, it was necessary for human beings to become aware of their relevance and to take care of making efficient use of trees, avoiding indiscriminate felling, an action that of course harms life on the planet.
But of course, it was not an easy job but finally the large companies that need trees to produce their products understood that going against them, using them in an irrational way, would also be seriously harmed in the future, so they took measures effective and developed protection policies in this regard.
Thus, the reforestation activity found a reason for being, which precisely proposes the generation of trees in the same proportion in which they are being used, so that they are never missing ...
It was understood that if a task such as reforestation is not carried out, sooner or later serious problems will be unleashed around the economic activity that they carry out and also in environmental matters, also taking into account that the population continues and continues to grow.
Dendrology is the discipline that deals with studying everything that is typical of these and for its part, forestry, deals with their scientific study and the inherent in the practice of their care and cultivation.
