Fras är ett Forskningsprogram som kommer drivas under 2018-2021. Sex nya doktorander inom skogsskötsel med frågor relevanta för södra Sverige har antagits. De sex doktorandtjänsterna fördelas inom ämnesområden som sammantaget berör beståndens hela omloppstid med fokus såväl på enskilda trädslag som på blandskog och generell hänsyn. Nedan följer en kort presentation av doktoranderna.
Etablering av tall: Mikolaj Lula (SLU)
Gallring och generell hänsyn: Delphine Lariviere (Skogforsk)
My PhD project within the FRAS "future silviculture in southern Sweden" research program. It will focus on biodiversity management in forest thinning. I will study the effect of different thinning regimes on different type of stands and/or forestry features as well as their repercussions on biodiversity and tree production. The aim is to understand how to adapt thinning templates to better suits todays more structurally complex new growing forest. Altogether my studies will allow us to draw an overview of the repercussions of thinning on forestry production while adding a consideration to biodiversity. These repercussions will be studied at different scales to better understand the challenges linked to biodiversity conservation. I will be one the student working both at SLU (Alnarp) and Skogforsk (Ekebo). The project is under the supervision of Jan-Olov Weslien (Skogforsk, Uppsala), Emma Holmström (SLU Alnarp), Rikard Jakobsson (Linnaeus University), and Babs Stuiver (Sveaskog).

Björkkvalitet i blandskog: Grace Jones (LNU)
Background: Bachelors of Forestry Science with First Class Honours (University of Canterbury, NZ). The dissertation I completed in my 4th year of study investigated how the treatments; stocking, wind-sway, genetics, weed control and fertilizer application, influenced stiffness estimates for 10-year-old Pinus radiata stems.
I spent 2017 working as a Graduate Forester in the Silviculture team for OneFortyOne Plantations in South Australia's Green Triangle region. This was predominantly working with P.radiata but there is also management of remnant patches of native trees, cultural sites, and other sensitive features.
PhD project: The purpose of the PhD project is to increase our understanding of specific stem and wood qualitative aspects for mixed birch-spruce forest stands in Southern Sweden. I will be investigating the genotypic variations among selected birch clones in terms of external and internal wood properties. I will also look at the impact of stand composition and proportion of species mixture on stem quality and wood properties.
Understanding how a stand develops over time from juvenile tree characteristics, and if there is a correlation to the final harvested timber, could improve forest management strategies for timber production. Information gained from this project will help with predictions of forest suitability for production of different timber grades, and improve efficiency by accurately allocating raw materials earlier.
This project includes working with supervisors Dr. Stergios Adamopoulos (from LNU), Dr. Mateusz Liziniwicz (Skogsforsk) and Dr. Mikael Andersson (SLU) on a range of established thinning and genetics trials throughout southern Sweden.

Målanpassad gallring: Magnus Persson (LNU)
Background: I come from Kristianstad in southern Sweden and I am 26 years old and I hold a bachelor and a master's degree in Forest science from SLU. During my studies, I have been an Erasmus-student at BOKU in Vienna, Austria, where I studied courses within the master's program "Mountain Forestry". I conducted my master's thesis in forest remote sensing, and my topic was "Tree species classification using multi-temporal Sentinel-2 data". Additionally, I have worked at different forest companies with forest inventory and forest planning during my studies.
Phd project: The possibility to vary the thinning strategy arise with increased knowledge about how site quality and stand structure varies within stands. Effects of varying the thinning strategy within stands will be evaluated with forest production and economy in mind, with the goal to optimize the time of thinning. Models which estimate the optimal time for thinning – based on remote sensing data – will be formed and evaluated.
My view on the future:
The supervisor group is constituted of Johan Bergh (LnU, main supervisor), Emma Holmström (SLU, assistant supervisor), Johan Sonesson (Skogforsk) and Magnus Petersson (Södra).
