Tree cover refers to the area of land that is covered by trees, including forests, woodlands, and urban areas with trees. It plays a crucial role in maintaining ecological balance, providing habitats for wildlife, and contributing to air quality by absorbing carbon dioxide and releasing oxygen. In addition to environmental benefits, tree cover also supports human activities by offering shade, reducing heat, and enhancing the aesthetic value of landscapes. Organizations like the Food and Agriculture Organization monitor tree cover to assess changes and promote sustainable management practices for forests and green spaces.
