Road building has a range of direct impacts on rainforest ecology. In wet tropical environments, the cut-and-fill operations associated with road construction can impede streams, increase forest flooding, and drastically increase soil erosion.
How will building a road through the rainforest affect the plants and animals?
Some consequences of building the road are that it will provide loggers access to highly-valued trees, provide a more accessible trade route for merchants and farmers, affect the wildlife and water quality in the area, and possibly cause indigenous populations to relocate.

What ecosystem is the rainforest?
BACKGROUND INFORMATION ON THE RAINFOREST
Rainforests are forest ecosystems characterized by high levels of rainfall, an enclosed canopy and high species diversity.
Why are rainforests important?
As well as the vivid beauty that comes with great diversity in plants and animals, rainforests also play a practical role in keeping our planet healthy. By absorbing carbon dioxide and releasing the oxygen that we depend on for our survival. The absorption of this CO2 also helps to stabilize the Earth’s climate.
How the construction of a road would negatively affect animals in the forest ecosystem?
Forest roads can cause a variety of impacts on local wildlife that may lead to extirpation: facilitating the spread of invasive organisms, causing death or harm by vehicle strikes, and changing the behavior of animals to their detriment.
