Eucalyptus camaldulensis Dehnh, is planted widely throughout the world, particulary in the mediterranean, and in the harsher tropical and subtropical climates. Although the species was introduced into Brazil early this century, commercial plantations are unknown and information on growth is scarce. With expansion of afforestation to more marginal areas, provenance trials were established on many sites in Brazil with seed sources representing the natural northen Australian range. Data were obtained for a period of seven yars growth. Three sites were selected for detailed studies of growth, volume, bark content, wood density, charcoal and pulp yield. E. camaldulensis was compared with Eucalyptus grandis Hill ex Maiden, E. tereticornis Smith, Eucalyptus urophylla S.T. Blake and Eucalyptus cloeziana F. Muell, for some of the charactes. Large variability appeared in all traits. At seven years, means for height and diameter were 13,5-18,1m and 11,3-14.1cm respectively. Genotype-environment interaction was weak contributor to the variation observed in rate of growth (9-11,2 % of the total variation) and it was not evident in wood density. Volume equations were derived for all species; those for E. camaldulensis could not be applied to other species except E. tereticornis. Bark percentage varied between species/provenances (13.8-37,0%) and sites (21-24%) and also showed genotype-environment interaction. Bark percentage at breast height was the best indicator for the total tree bark content. Form factors with and without bark were variable and the former was consistently smaller for almost all provenances. Form factor over bark is not a reliable correction factor for estimating volume under bark. Provenances showed patterns of geographic and climatic variation in wood density and mathematical models were derived with latitude and rainfall as the best explanatory variables. Charcoal and pulp yield were related to wood density. Species/provenances with higher rates of growth and higher wood density (e.g. E. camaldulensis from northern Queensland)...
