I am studying the role of fire in the sub-alpine forests and heathlands of the Bale Mountains in Ethiopia. I am specifically interested in Hagenia abyssinica, a tree with high quality timber and flowers containing medicinal compounds. Hagenia is one of Ethiopia's most threatened tree species due to excessive logging and poor regeneration. Hagenia is a pioneer species and does not regenerate in the old-growth forest. Also, the saplings are badly affected by browsing, both by domestic and wild animals. My hypothesis is that hagenia regeneration is promoted by fire, which is supported by my observations of charcoal in deep soil layers and regeneration in recently burnt spots. I am analyzing forest fuels, fire behaviour and the effects of fire on soils and forest and heathland regeneration. I am also studying the traditional fire management system of the subalpine pasture heathlands. My supervisors are Dr Anders Granström, Professor Anders Malmer and Professor Masresha Fetene.
