Forest inventory is the systematic collection of data and information for assessment or analysis of forest resource. The aim of the statistical forest inventory is to provide comprehensive information about the state and dynamics of forests for strategic and management planning. Monitoring forest cover and loss is critical for obtaining the data necessary to help define what is needed to maintain the varying forest service requirements. There is an increasing need for timely and accurate forest change information, and consequently a greater interest in monitoring those changes. Remote Sensing for Forest Monitoring and Management is a good way to monitor changes in forests. When taking a forest inventory you must measure and note the following: species, diameter at breast height (DBH), height, site quality, age, and defects. Data collection allows you to calculate the number of trees per acre, basal area, volume of trees in an area, and value of the timber. Inventories serve many purposes. They allow you to estimate the value and possible uses of timber, an important part of the broader information required to sustain ecosystems. Inventories can also be used to visually assess timber and determine potential fire hazards and the risk of fire. The results of the inventories can be used in biodiversity conservation.
