In our language we call as bush To that plant that boasts a long life and is physically characterized by its medium height, its woody and short stem and the presentation of branches from its very base.
Its structure is specially made up of wood, cellulose and lignin.
Although shrubs share many characteristics mentioned above with trees, namely that they are perennial and have firewood or wood in their stem, it should be noted that the main differences between the two and through them we can precisely differentiate and distinguish them is that the shrubs they are much lower with respect to the trees (they oscillate in less than eight meters high), which tend to reach certainly considerable heights.
And on the other hand, they distance themselves from the trees in that the bushes are not erected on a trunk only, but their base already has ramifications, that is, it is a plant that has many more ramifications than a tree has.
The landscape in which the presence of shrubs is abundant and stands out is formally called scrub. Turf, grasses and plants that grow underground, also known as geophyte plants, are usually added to this biome accompanying the landscape of shrubs.
Now, it is important that we highlight the bushes and their main species can occur naturally in a geographical site, that is, they result from the climatic conditions and the characteristics of the soil of that space, or failing that, they can be a result of the activity of man, that is, the human being promotes and develops the scrub with his action.
It is worth noting that the climate is of great influence when determining the type of existing scrub. Thus, in desert climates there is the xerophilous scrub, whose plants are ideally adapted to this type of rather dry climate, observing in their format physical characteristics that allow it, such as having rather small leaves to avoid the loss of water or the arrangement of thorns that allow them to defend themselves against typical pasture animals.
