Inventories permit better hazard reduction, budgeting, and work planning. Every inventory includes at least address, species, size, condition, hazard potential, and necessary maintenance work. Its information is usually highly detailed and very accurate. The information is commonly less detailed and less accurate, and hazardous trees must still be examined by a qualified inspector. All inventories need to be updated periodically through ground inspection in order to stay current.
Cost depends upon who does the inventory, and how many trees there are.
The cost of an amateur inventory lies principally in the collection of ground inspection data, since data entry can often be carried out by existing staff.
