PLANTATION INVENTORY UNIT

Plantation inventory Unit was established in 1993 with the clearcut mandate to carry out inventorisation of the existing Teak plantations and to assess the productivity of the Teak plantations so as to estimate the total growing stock and it's value.

METHODOLOGY :

  • Phase-I data of Teak plantations raised from 1970 to 1987 and Phase-II data of Teak plantations raised from 1988 to 2010 are being taken for measurement and inventorisation.
  • Permanent sample plots of size 0.25 ha (50 mts × 50 mts) with sampling intensity of 1% were laid out in the Teak plantations by random sampling method to act as representative.
  • Measurements as well as inventorisation of growing stock are carried out in each of the sample plot so as to get a clear cut idea about the changes in the growing stock as a result of the thinning carried out , transition from lower girth class to the higher girth class, changes in the no of trees remaining etc.
