Some of the Terrestrial ecosystems of Mexico Are broad-leaved tropical and subtropical moist forests, tropical dry and subtropical broad-leaved forests or flooded grasslands and savannas.
In Mexico , There is a wide variety of marine, freshwater and terrestrial ecosystems. This variety of Ecosystems Has made Mexico the habitat of just over 12% of all the world's biodiversity.

In fact, there is such a variety of ecosystems and species That Mexico has been included among the megadiverse nations of the world, which are only 17 across the globe.
The Tropic of Cancer divides the country into two different climatic zones: to the north of Mexico one experiences a temperate climate, whereas in southern Mexico the climatic conditions are rather tropical.
This variety of climatic conditions, added to the diversity of ecosystems in Mexico, favors the presence of more than 200,000 species.
Mexico's terrestrial ecosystems are usually divided into nine categories. These categories are established taking into account the vegetation of the area, altitude, climatic conditions and precipitation.
The following is a list of the types of terrestrial ecosystems in Mexico followed by a list of areas of Mexico that constitute terrestrial ecosystems.
Main types of terrestrial ecosystems occurring in Mexico
Among the terrestrial ecosystems of Mexico, the following stand out:
Rainforests or everlasting tropical forests
They are one of the most complex ecosystems and richest in diversity on Earth. It has been established that more than 50% of all animal and plant species live in these forests.
Tropical rainforests are found in lowlands, which do not exceed 1200 meters above sea level. Annual precipitations are abundant (between 150 cm 3 And the 400 cm 3 And temperatures usually exceed 20 ° C (usually between 20 ° C and 28 ° C).
They are also called semi-permanent forests because more than 75% of the plant species maintain their leaves throughout the year.
Tropical deciduous forests
Temperatures in deciduous forest are warm all year round. There are two climatic seasons: one rainy and one dry. Like rainforests, they are found at altitudes lower than 1200 meters above sea level.
Between 50% and 90% of tropical deciduous forest trees lose their leaves during the dry season (hence the name) to reduce water loss. The trees in these forests are not as close to each other (as they are in tropical rainforests).
Prairies
Grasslands or pastures are found in regions where the topography is smooth and undulating. The vegetation in this type of ecosystem is smaller size (between 60 cm and 90 cm).
In the prairies there are also two seasons: one of rains and one of drought. The period of drought is long, since it lasts between six and nine months.
The annual rainfall is between 30 and 60 cm 3 . Meanwhile, temperatures range between 12 and 20 ° C.
Xeróphytes scrub
In this type of ecosystem the predominant vegetation is the typical one of the desert: thorny bushes, of small leaves, like the cactus .
The temperatures are extreme and can reach up to 42 ° C. Meanwhile, annual rainfall does not usually exceed 70 cm 3 .
Areas of Mexico that constitute terrestrial ecosystems
The following is a list of terrestrial ecosystems in Mexico, available on the web site of the National Commission for the Knowledge and Use of Biodiversity (Conabio, Mexican organization).

In this list, terrestrial ecosystems are classified, taking into account the guidelines of the World Wide Fund for Nature (WWF).
Logo of the World Wide Fund for Nature (WWF)
The classification categories of the WWF are nine and are as follows: tropical humid forests and subtropical broadleaf; Tropical dry and subtropical broadleaf forests; Tropical and subtropical coniferous forests; Meadows, savannas and tropical and subtropical scrub; Grasslands and flooded savannahs; Meadows and montane scrub; Mediterranean forests and scrubland; Deserts and shrublands of desert vegetation; And mangroves.
