Develope the management of mixed forests in southern Sweden.

The forest is an important resource. A great deal of expectation is placed in the forest as one of the solutions to reduce the negative effects of a changing climate. But what role the forest should have in a green transition is not conflict-free. The forest is expected to produce fossil-free raw material, store carbon and at the same time preserve important natural and cultural values. This entails major challenges for forest management. Do you want to contribute to the development of forest management in southern Sweden to meet the needs of the future?

If yes, a PhD or postdoc position in FRAS II can be something for you. FRAS II is a research program jointly run by Linnaeus University (LNU), Skogforsk and the Swedish University of Agricultural Sciences (SLU) in close cooperation with the forest sector in southern Sweden. It is a continuation of the research program FRAS that was run 2017-2022. FRAS II consists of three PhD projects and three postdoc projects that focus on different aspects of forest management.

The project

Mixed forest can increase variety and benefit biodiversity in the forest landscape. Planting mixed forests can also be a way to spread the risks of a changing climate and a changed damage pattern. At the same time, the certification standards of forestry require long-term admixture of broadleaves in conifer-dominated stands.

By planning for mixed forest already at an early stage, we believe that regeneration, clearing and thinning can be made more efficient. It can be about planning for natural regeneration of broadleaves or planting broadleaves together conifers. It can also be about planning the spatial distribution of the mixture. The opportunities to influence the forest development and structure through management are greatest in the young stand. Clearing therefore becomes an important part in shaping the future stand. The focus of the project will be on mixed stands with spruce and birch, but methods to increase the element of rare broadleaved species in practical forestry will also be highlighted.

The doctoral project will develop and evaluate effective methods for the establishment of long-term mixed forests with good profitability. Establishment and early management will be studied in field trials. Simulation tools may be used to estimate the long-term effects of the methods on stand development and economy. The doctoral student will participate in the communication and implementation of the research results.


The applicant should have obtained an MSc in Forest Science at the time of admission as a PhD student. Knowledge in forest management, experience with statistics and data processing and with the simulation tool such as Heureka are meritorious. We also see that the applicant has good skills in written and oral communication in English. A driver's license is required in the position. Ability to communicate in Swedish is desirable but not a requirement.

The application must contain: a letter with expectations on the position and what you personally find interesting within the silviculture research subject (max 1 page), CV and contact information to two reference persons.
