Forest cover refers to the amount of land covered by forests, including both natural and planted forests. It is an important measure of the extent and health of forest ecosystems, as well as their ability to provide vital ecosystem services such as carbon sequestration, biodiversity conservation, and water regulation. Monitoring changes in forest cover over time can help assess the impacts of deforestation, logging, urbanization, and other human activities on forest ecosystems. Researchers may use satellite imagery, field surveys, and other methods to track changes in forest cover and promote sustainable forest management practices.
