Forest inventory is the practice of collecting data on the health, composition, structure, and productivity of a forest ecosystem. This data is used by foresters and resource managers to make informed decisions about how to sustainably manage and conserve forest resources. Forest inventory techniques may include field measurements, remote sensing, and statistical modeling to estimate forest attributes such as tree species, age, density, volume, and carbon content. This information helps to inform forest management strategies, monitor changes over time, and assess the overall health and productivity of forests.
