A tree inventory should provide tree species, preferably in binomial nomenclature (Latin names), size, such as DBH (diameter at breast height) and tree height, crown width, overall condition such as health and maintenance needs, overcrowding, possible problems, presence or absence of insects or diseases. Characteristics of the site should also ...
When taking forest inventory the following are important things to measure and note: species, diameter at breast height (DBH), height, site quality, age, and defects. From the data collected one can calculate the number of trees per acre, the basal area, the volume of trees in an area, and the value of the timber. Inventories can be done for ...
