Johan Bergh

Some people know exactly what career they wish to pursue. For me, my choice of education was rather random – the educational programme in Forestry was my third choice. However, I think it all turned out well, especially given the opportunity to interact with Swedish forestry and the surrounding community. I see myself as a generalist and interdisciplinary collaboration greatly stimulates me. I always seek to explain and understand why things are the way they are.

My area of expertise is ecophysiology, forest production and forest management, all linked together by the effects of climate change. My work mainly concerns how nutrient dynamics and climate change may affect boreal forest ecosystems, including risks related to climate change. Adapted forest management is one way to take advantage of the new situation, to handle potential risks and to minimise damage.

My work also includes how to manage the forest to mitigate effects of climate change through uptake/storage of carbon dioxide and through an optimal usage of the forest raw material. Collaboration with the Swedish forest industry and society constitutes a big part of my work. I also work internationally to give advice on plantation forestry.
