FOREST INVENTORY



     A forest inventory is often termed a “timber cruise”.  A timber cruise is an
     inventory of a forest stand to determine the quantity of forest products that
     can be derived from the stand.  In addition to timber quantity, a cruise
     often contains information about species composition, age, tree quality,
     site quality, topography, and operability for logging.  It also can include
     data on growth, down woody material, snags, understory vegetation, and
     other resources.

     developed by Northwest Forestry Services for one of its clients, but the
     names, dates, and legal descriptions have been changed.

     Northwest Forestry Services has cruised or examined over 800,000 acres
     of forestland in the Pacific Northwest.  Resources examined range from
     reproduction to old growth.  Assignments have ranged from a few acres
     to tens of thousands of acres.

     A “typical” cruise report includes a Property Description and Timber
     Inventory Data as detailed below.  Some cruises contain additional
     information, as described under the “Other Inventory Data” heading.
