Forest Mensuration includes measurements of § Felled and standing trees, § Sawn wood and round logs and bamboos § NTFPs such as bark, roots, fruits, etc Forest Mensuration, therefore, concerns with linear, area, volume and weight measurements.

Now mensurationist has to concern himself with the measurement problems of wild life management, watershed management, insect and disease incidence, recreation, tourism and many of the mensurational aspects of multiple-use forestry. The application of statistical theory and the use of electronic computer for data processing have brought about revolutionary changes in forest measurement problems.
