What are green giants?

They are large trees, with more than 1.5 meters of trunk perimeter measured at 1.3 meters from the ground and which have the capacity to host a large number of organisms.

As the trees grow, they accumulate structures that act as shelter for a large number of living beings. They are called microhabitats and can be, for example, cavities, dead branches, wounds on the bark, among others. In total there are 64 different structures that can be found in the Catalog of microhabitats, developed by the  Integrate+ Project.

Over the past few years, efforts for nature conservation have been increased, which can be seen in the creation of national parks and other areas designed for this purpose, however there is still an increase in species that disappear every day.

More and more people have been alerted to the importance of starting to integrate concrete actions of nature conservation in the activities and places that man manages for his own benefit, such as forests, agricultural fields or urban areas.

This is where large trees come in.


Trees, in addition to giving us oxygen and fixing atmospheric carbon, giving us resources such as wood or fruit, usually have associated cultural and historical values, especially those we encounter in our daily lives and which are in our gardens , public parks and private properties.

In a landscape increasingly transformed by man, it is important to conserve the few places that have the capacity to remain constant for several years and that thus allow the existence of life for decades.

Trees of high ecological interest, usually also have unusual dimensions and therefore have a greater capacity to support microhabitats that allow the occurrence of these living beings.

The trees that surround us are thus fundamental pieces to conserve the nature that surrounds us and that is why it is up to all of us to help in their conservation.
