Experimental forests are designated areas where scientists conduct research on forest ecosystems. These forests allow researchers to study various aspects of forest health, growth, and biodiversity. They often focus on understanding the impacts of climate change, pests, and diseases on trees and other plants. In these controlled environments, scientists can test different management practices and restoration techniques. Experimental forests contribute valuable data that helps inform policies and practices for sustainable forestry. They are often part of larger networks, such as the U.S. Forest Service or National Forest System, which aim to promote healthy and resilient forest ecosystems.
