The experience and best guesses of forestry personnel in the Inverell District of NSW were used to compile a list of commercial sawlog volumes in each compartment of a large management area comprising 430 000 ha of forest and woodland. The data were stored in a standard format in a newly developed Forested Area Management Information System (FAMIS) and then sampled to determine whether the guessed volumes were correlated with inventory based estimates. The correlations were strong and allowed estimates of sawlog volumes by compartment to be derived with confidence limits of #xB1; 13 of the mean for a total cost of less than $0.50/ha.
