a Rainforest Tree
Trees are the foundation of the rainforest. Without trees, there would be no forest in rainforest, just rain. And all that rain is very hard on the ground when there are no trees, and causes a lot of erosion.
This tree is Pterocarpus, a special tree because of its bizarre roots above the ground. These "buttressed" roots spread out in all directions from the trees. Pterocarpus uses these spreading roots to capture nutrition from the ground a long way from the trunk.
Tropical rainforest trees
often have spreading roots. It is different than trees in the United States,
in what is called a temperate forest. In a temperate forest, trees need
to send a root deep to get water and have one big root going down with
small roots going to the sides. In the rainforest, there is a lot of water
so they don't need the big root going down. But there is little nutrition
in the soil, so the tree must spread its roots out in search of nutrition.
