Dr. Gina Elizabeth Hannon

Gina is a botanist with keen interest in the history of vegetation communities which she studies using geological techniques. Of particular interest, is the role man has played in shaping the vegetation we see on the landscape today, whether it be as a result of direct or indirect anthropogenic impact. This has led to a research career in Botany, Geology and now in the Faculty of Forestry at the Swedish University of Agricultural Sciences. Published research includes the history of first human impact on the Faroe Islands and Iceland, as seen in the fossil record, and the underlying climatic control, which has shaped pre-settlement vegetational development. Current research activities which focus on the analysis of plant macrofossil seeds, fruits, leaves, bracts and wood, includes the study of treeline movement over the last 6000 years in northern Fennoscandia and the history of the expansion of Beech (Fagus sylvatica) into southern Scandinavia. Gina also is working on the history of the Swedish "forest meadows" on the Bjäre peninsula, by looking at their plant communities as seen in the plant macrofossil record over the last 2000 years.

Gina is from Ireland and did her first two degrees at the Department of Botany, Trinity College Dublin. On moving to Sweden in 1988, Gina took up a position at the Department of Quaternary Geology at Lund University. Her Phd “The use of Plant Macrofossils and Pollen in the Palaeoecological Reconstruction of Vegetation” was completed in 1999. She has worked as a researcher and teacher of forest ecology and forest history at the Southern Swedish Forest Research Centre since 1998.
