Forest - area of one hectare or more which is at least 10 percent stocked with forest trees
             (including seedlings and saplings), wild palm, bamboo or brush. Narrow strips of land
              bearing forest must be at least 60 meters wide and one hectare in size to qualify as
              forest. Industrial tree plantations and tree farms one hectare or more in size are also
              included. 

Forest Land – includes the public forest, the permanent forest or forest reserves, and forest
              reservations. 

Forest Product - all usable raw materials yielded by the forest including the associated water,
              fish, game, scenic, historical, recreational and geologic resources. 

Log - felled trees bucked into convenient length of at least 1.5 meters, with at least 15 cm. in
              diameter. It may either be poles, piles, pulpwood, sawlog or veneer log. 

Lumber - solid wood not further manufactured other than sawing, resawing and passing
              lengthwise through a standard planning machine crosscut to length.

Non-Timber Forest Product - includes all forest products except timber; also known as minor
              forest product. 

Plywood - an assembled product made of layers of veneer held together by an adhesive, the
             chief characteristic of which is the alternate cross layers, distributing the longitudinal
             wood strength. It consists of three or more layers of veneer, firmly glued together
             with the grain direction of the middle layer at right angles to that of the two parallel
             outer layers. 

Poles and Piles – logs for use as electric post, pier piling, railroad ties, sleepers and the like.

Pulpwood – any wood commercially used for the manufacture of any type of pulp. 

Roundwood - wood in its natural state as felled or otherwise harvested, with or without bar,
              round, split roughly squared or other forms (e.g. roots, stumps). It may also be
              impregnated (e.g. telegraph poles) or roughly shaped or pointed. It comprises all
              wood obtained from the forest such as sawlogs/veneer logs, pulpwood, fuelwood
              and other industrial roundwood.

Timberland – refers to land of the public domain which has been the subject of the present
              system of land classification determined to be needed for forest purposes. 
              Eventually, these lands will be proclaimed as forest reserves by the President. 

Upland – highland; ground elevation above the lowlands along rivers or between hills.

National Park – refers to a forest reservation essentially of primitive or wilderness character
              which has been withdrawn from settlement or occupancy and set aside as such

              manner as will leave them unimpaired for future generations.
