Persona avatar

Marit Halvorsen

Associate Professor of Forest Ecology · Docent

Forest ecologist working on soil carbon, deadwood decay and peatland hydrology in boreal Fennoscandia. Principal investigator of the Storbäcken plot network, remeasured every autumn since 1994. Considering senior appointments from January 2027; open to collaboration and to doctoral applications for autumn 2027.

Appointments

Associate Professor of Forest Ecology

Nordvik University · Umeå, Sweden

Principal investigator of the Storbäcken plot network and four associated experiments. Group of one postdoc and four doctoral students. Teaching load of two courses plus a doctoral course. Docent conferred 2022.

Assistant Professor, Forest Ecology

Nordvik University · Umeå, Sweden

Took over the Storbäcken network on Bengt Åkerlund's retirement, digitised the 1994-2016 record, and secured the infrastructure grant that keeps it running.

Researcher, Boreal Soils Programme

Nordic Institute for Water Research · Oslo, Norway

Peatland carbon and hydrology. Built the paired-mire design later used at Rävmyran, and learned to write a grant that a hydrologist would sign.

Postdoctoral Researcher

Bjørnfjord University · Bergen, Norway

Deadwood decomposition and fungal community assembly. Two field seasons in western Norway, one very wet.

Field assistant, then doctoral student

Storbäcken Research Forest · Västerbotten, Sweden

Six autumns on the plots before I had any business having an opinion about them. Still the most useful training I have had.

Education

PhD, Forest Ecology

Bjørnfjord University · Bergen, Norway

Thesis: Mass loss and fungal succession in Picea abies deadwood. Supervisor: Prof. Bengt Åkerlund. Defended with distinction.

MSc, Biology (Ecology)

Bjørnfjord University · Bergen, Norway

Thesis on ground layer recovery after selective felling. First field season at Storbäcken.

BSc, Biology

Bjørnfjord University · Bergen, Norway

Came for the marine biology, stayed for the soil.

Grants and funding

Boreal Carbon Programme

Nordic Research Council · 14.2 M SEK · principal investigator

Soil carbon recovery after disturbance across the full plot network, with a synthesis work package.

Long-term plot infrastructure

Vinter Foundation · 8.6 M SEK · principal investigator

The grant that pays for the autumn remeasure, the archive and the boardwalks. Renewable, and renewed twice.

Peatland rewetting, paired mires

Nordic Research Council · 6.1 M SEK · co-investigator

Instrumentation and five seasons of flux measurement at Rävmyran and three paired sites.

Doctoral position, deadwood fungi

Nordvik University · 3.4 M SEK · supervisor

Four-year funded position, currently held by Tuva Lind.

Deadwood synthesis working group

European Forest Network · 1.9 M SEK · work package lead

Pooling twenty-nine datasets from six countries into one open decay model.

Teaching and supervision

Boreal Forest Ecology (FE3021)

Master's · 15 ECTS · course leader

Designed and still run. Six weeks of teaching, two weeks on the plots doing a real remeasure.

Soils and Carbon (FE2110)

Bachelor's · 7.5 ECTS · co-taught

The large undergraduate course; I take the carbon half and the laboratory.

Long-term Ecological Research: Methods and Ethics (FE4400)

Doctoral · 5 ECTS · course leader

Twelve students a year, half methods and half the awkward questions about succession and stewardship.

Doctoral supervision

Seven completed, four in progress

Principal supervisor for eight, co-supervisor for three. All seven who have finished are still in science or in forest management.

Field Course, Västerbotten (FE1005)

Bachelor's · 7.5 ECTS · course leader

Ten days in the forest with first-years. Handed over in 2022.

Service, review and outreach

Associate Editor

Journal of Boreal Ecology

Panel member, research infrastructure grants

Faculty of Forest Sciences, Nordvik University

Reviewer

Twelve journals · roughly twenty manuscripts a year

Public lectures and forest walks

Schools, libraries, forest owners' associations

Free for anyone who is not a company. Around eight a year, more in spring.
