About the Forest
An ecosystem is a natural system formed by a collection of live organisms, such as plants and animals, and the physical environment in which they live (such as rocks, soil, water, etc.). The U.S. Forest Service (USFS) manages 193 million acres of National Forests and Grasslands and their diverse ecosystems.
Some information about the importance of our National Forests and Grasslands:
- The USFS manages the largest single source of water in the U.S.–almost 20% of all the water in the country–providing drinking water to more than 180 million people.
- Natural areas help to alleviate climate change because they capture and store carbon dioxide; about 20% of a tree’s weight is made up of carbon.
- There is great biodiversity in and our forests and grasslands, including critical habitat for the conservation of plant, animal and insect species in danger of extinction.
- They provide wide-open and safe spaces where everybody has the chance to recreate and share with family and friends.
- There are many specialists working together to ensure that our natural public areas are sustainable and healthy today and for future generations.
