The Evergreen Forests found in Mexico~ General Information

The tropical evergreen forests, rainforest, found in Mexico is one of the richest and most complex forests in the world. The precipitation found in this forest (usually higher than 250cm!) allows for multiple animals to thrive in the area. So much that more than 50% of all animal and plant species live here! To add on, 75% of plants maintain their leaves all year round! Another thing that is special about this evergreen forest is that it contains a vertical stratification. It consists of five layers that layer on top of one another. The first layer consists of trees that spread and are from 30 to 40m tall. These trees tend to have small pointed leaves and become deciduous during dry windy weather. The second layer contains trees that are 25m tall which allows light to shine at the top of trees but not towards the roots. The third layer contains trees that are 20m tall. Humidity levels are high in this area. The fourth layer has a limited amount of light (about 3%) thus is where shrubs commonly grow. The fifth and last layer has very sparse plant growth because less than 1% of light strikes it. Moisture is also reduced.
