The science of forest mensuration deals with measurement in the tree, the measurement
of stands, forest survey in a large area and the determination or prediction methods of the stand increments.
( a ) Measurement in the tree :
In the measurement of the standing trees, the volume have need to be measuerd more accurately. On the other hand, it is necessary to regulate the method of the measurement of leaves, branches, stems and roots.
( b ) The measurement ot stands :

The better methods of plot sampling and plotless sampling of estimating stand volume are essentially.
( c ) Forest survey in a large area :
Aerial photographs completely cannot replace ground methods in forest mensuration, but they can yield much information more quickly than the ground methods in a large area.
( d ) The determination or prediction methods of the stand increments :
W. H. Meyer, H. S. Spurr, F. Loetsch, E. Otomo, M. Nishizawa and K. Kinashi have studied the new methods of growth prediction commonly used today.
The estimation of growth is an essential problem in forest management.
