Abstract Forestry workers have previously been identified as an occupational group at high risk of work-related injury. This paper reviews factors affecting injury among forestry workers and draws on international literature in general (New Zealand studies in particular). A major proportion of the literature relates to tasks involving chain saws, such as felling and delimbing, and the operation of forestry machinery. By comparison, less attention has been given to tasks such as tree planting and pruning. And while physical risks have been well documented, comparatively little research has focused on mental workload, particularly in relation to motor-manual logging. Few studies have focused on the effects of work organization (e.g., hours of work, contracting) on injury rates.
