What is a tree?

Trees are the largest woody plants. To consider a plant to be a tree, it must be at least five meters long, and have a clearly distinguishable trunk and crown. In front of them, the bushes are woody plants whose branches are at ground level.

Due to its geographical and climatic diversity, Aragon has a great variety of trees.

The parts of a tree are the following:

• Trunk

  It is the support of the visible part of the plant, the stem of the trees is called the trunk, due to its solid and woody appearance.
  The medulla runs through it, surrounded by the central cylinder, vascularized, and covered by the cortex. Slender or thick, straight or twisted, the trunks have varied shapes and designs.

• Leaves

  They are the parts of the tree that sprout from the branches, the leaves are entrusted with the primary mission of assimilating carbohydrates, from the conversion of sunlight into accumulated energy. Due to their external appearance, they are susceptible to a first division into acicular ones, typical of conifers, and those with a flattened blade, typical of planifolios.

• Roots

  The roots are the part of the tree that grows underground. They serve both for fixation and for the extraction of water, nitrogen, and carbon that will be transformed into food for both the plant itself and other beings.

• Flowers and fruits

  They are the reproductive structures of angiosperm plants, the flowers produce pollen that, transported by the wind or animals, will make fertilization possible.
  The fruits, for their part, contain the seeds that after their dissemination and germination will give rise to new plants.

• The Crusts

  They can be rough, smooth, striated, thick, cracked, etc., all tree barks have specific features or hallmarks that characterize them and this is very important information to be able to correctly identify each species of tree.< /p>

Distribution

Like the rest of living beings, trees also have their preferences when choosing their living space. Geobotany or Phytogeography studies this distribution of trees in a specific geographic framework. And there are many factors that enable or prevent the presence of trees on the ground.
The scarcity or abundance of water, the composition of the terrain, the altitude, condition its presence.

A small choice of environments would be the following:

• Mountain Forests

  The climate of the heights is very demanding and only a small group of species can tolerate it. It is estimated that every 100 meters of altitude the average temperature drops 1ºC; few species can withstand these conditions. Among these are black pines and firs.
  It is the type of trees that we can find in some parts of the Ordesa y Monte Perdido National Park, or in Moncayo.

  

• Atlantic forest

  This is produced by the humidity and sweetening due to the Atlantic influence that is felt in the leafy forests, mostly deciduous, of the western valleys: Anso, Hecho and Tena.

• Mediterranean mountain

  What distinguishes it from the previous ones is sclerophyly, which is defined as "hardness in the leaves." This is the method that plants in this environment have to defend themselves from the atmospheric conditions that occur especially in summer where the lack of rain combines with high temperatures.

  

• Steppe plain

  The scarce presence of trees in the central depression of the Ebro Valley is due, not only to the harshness of the climate, but also to the rural development policy followed in Aragon in the past.
