Canopy cover refers to the layer of leaves and branches formed by the upper parts of trees in a forest. This layer plays a crucial role in the ecosystem by providing shade, reducing soil erosion, and supporting various wildlife habitats. The amount of canopy cover can influence the overall health of a forest and its ability to store carbon. Measuring canopy cover helps scientists understand forest density and biodiversity. It can be assessed using various methods, including aerial photography and satellite imagery. High canopy cover often indicates a healthy forest, while low canopy cover may signal deforestation or environmental stress.
