Abstract

Renewal of volume using inventory sampling known as 3P replaced the one hundred percent renewal in northern forests from 2000 up to 2001 to decrease field works and costs and enhance the forest interprise. In this method after choosing sample trees among marked trees, its field operations starts with measuring the volume of industrial and fire wood of sample trees for each authorizer cut and the obtained coefficients were generalized to all trees of same cut authorization. To assess and compare the precision of 3P METHOD with 100% volume renewal a study is conducted in restored and semi-degraded forests in Babolkenar forestation plan district 2 part 10 on two species: Parotia persica and Carpinus betulus. After generalization of industrial coefficient of 3P METHOD in total volume, industrial volume was 1.8% less than 100% industrial volume in Parotia persica and in Carpinus betulus after generalization of industrial coefficient 3p in total volume, industrial volume had 3.9% difference to 100% industrial volume. In this method, we saved both the time spent measuring sample trees of 3P (field work) compared to 100% volume renewal and the cost of operation (about 33%) and the time for calculation of volume. However, writing volume renewal (staff work) is also saved about 23%. It could be expected that following the technical principles in cutting, measuring, computation and also improving volume tables of 3P METHOD gives logical and acceptable results.
