Abstract
Proper management of irrigated forest plantations requires special management aids. Tariff tables are among the most important tools in managing forest plantations. This study presents tariff tables for Eucalyptus camaldulensis and E. microtheca in the Rahad Agricultural scheme. For the construction of the tariff tables, 114 trees of Eucalyptus camaldulensis and 75 trees of E. microtheca were felled and their stems measured in order to determine their diameters at breast height and actual volumes. Using regression techniques, the relationships between diameters and volumes of the stems of each group of data were determined. The strong correlation between these parameters (diameter and volume) made it possible to construct the tariff tables. Using those tariff tables, volumes of trees of the above mentioned tree species can be calculated by measuring diameters only. This saves a lot of time spent in forest inventories. The tariff tables presented here are applicable for the irrigated plantations of the Rahad Agricultural Scheme. Their use elsewhere or for those of coppice origin requires careful tests.
