You will take on the role of ecologists working for Natural Resources Rescue, an organization that works to protect and save fragile ecosystems around the world.
This is a project report from Natural Resources Rescue (NRR) about the problem in a part of the Costa Rican rainforest ecosystem. The project area was originally a healthy rainforest. Then, as you can see in the photo on the left, cattle ranchers burned down the rainforest so they could use the land as grazing (eating) area for their cows.
Several years ago, the cattle ranchers left and took the cows with them. The ranchers were asked to plant trees so the area would become a rain forest again. As you can see in the photo on the right, some trees—called cecropia trees (pronounced see-CRO-pee-ah)—and other rainforest plants are slowly starting to grow again, and rain forest animals have begun to come back.
NRR worked with volunteers to replant the project area. They brought in young cecropia trees and other important rainforest plants and planted them.
In many parts of the world, people have done reforestation projects like this, and the forest has grown back and thrived.
