Most parts of the Mwanza and Shinyanga regions of Tanzania face fuelwood and building-pole shortages. Two experiments using a total of 12 provenances of Eucalyptus camaldulensis Dehn. of Australian and local origin were tested at Igwata Forest Reserve, Tanzania for possible use in fuelwood and pole production. Assessment and analysis of data from the two experiments were made for survival and height growth, and for Image development. Growth after 27 and 41 months in the two experiments indicate no significant differences in survival. Significant differences were, however, observed in height and Image growth. It appears that Queensland provenances are the overall best-suited, followed by provenances from Northern Territory, Western Australia and Victoria. Limitations of the provisional results are outlined. Further trials with seed sources from Northern Australian provenance groups are recommended. A rotation age of about 4 years appears suitable for fuelwood, whereas a longer period might be needed for pole production if wood impregnation is not anticipated.
