Seminar announcement: ‘Drought impacts on forests – potential adaptation strategies’ (July 2, 2018)

Sumforest – ForRISK invites you to attend

Drought impacts on forests – potential adaptation strategies

At Room 200, 2nd Floor Herderbau, Tennenbacher Str. 4, 79106 Freiburg, Germany.

On Monday, July 2nd 2018,

From 2:00 pm to 6:00 pm.

The seminar will feature six presentations on different aspects of drought impacts on forests and potential adaptation strategies. Droughts can alter the conditions in which trees grow and regenerate, triggering changes in the productivity, structure and composition of forests. Such events and their impacts on forest ecosystems need to be understood, in terms of both the climatic drivers that determine exposure and the mechanisms that affect system sensitivity. Forest management can play a crucial role within the context of global climate change, by adopting effective strategies to minimize drought impacts on forests and their ecosystem services. The seminar is organized by Sumforest – ForRISK within the network of the NFZ.forestnet.

Attendance at the seminar is free of charge.

For further information, please see the official Seminar Announcement.

We look forward to seeing you in Freiburg at the seminar.

Welcome, Julien Sainte-Marie

Sumforest – ForRISK welcomes Julien Sainte-Marie as new postdoc at INRA. Julien previously worked as postdoc at the Research Unit for forest ecosystem biogeochemistry (BEF), INRA, France. He will work together with Matthias Cuntz on the ForRISK Work Package 2 – Investigation of the ecophysiological mechanisms during and after extreme drought in relation to tree population density of Norway spruce and silver fir stands.

Postdoctoral position at INRA Nancy

This position has been closed to new applicants.


Postdoctoral Position in Modelling Carbon Allocation and Tree Hydraulics (INRA Nancy, France)

We are looking for a postdoc to model carbon allocation and tree hydraulics. The position is within the European project ForRisk, which studies the interactions of drought and tree population density on the resistance and resilience of tree growth of Norway spruce (Picea abies) and silver fir (Abies alba). It combines a large dataset from long-term experimental management stands in Germany, France and Switzerland with a mechanistic ecosystem model and a forest succession model including forest management and ecosystem services, yielding economic risk-assessment at different spatial and temporal scales.

The postdoc will provide mortality rates for the risk-assessment model ForClim (Rasche et al. 2011) by modelling tree mortality with the ecosystem model MuSICA (Ogée et al. 2003) under different forest management strategies and climate change scenarios. MuSICA is among the most advanced multi-layer soil-vegetation-atmosphere transfer (SVAT) models, based on ecophysiological process representations and includes, among others, species competition for a limited number of resources such as light and water. The postdoc will enhance MuSICA by incorporating carbon allocation including carbohydrate stores, yielding carbon starvation during drought, as well as tree hydraulics, which may lead to hydraulic failure during drought.

ForRisk combines researchers from the NFZ.forestnet that connects six research institutions from Nancy (France), Freiburg (Germany) and Zurich (Switzerland). The postdoc will work with the partner institutions, forming the link between the data-centred work packages and the economic risk-assessment tool. S/he will also work closely with the main developer of the ecosystem model in Bordeaux (J Ogée). MuSICA is written in Fortran. Strong programming skills are required.

The position is based at INRA Nancy (France) in the Joint Research Unit (UMR 1137) of Forest Ecology and Ecophysiology (EEF). It is for a duration of three years, starting as soon as possible. Salary level will correspond to “Chargé de Recherches, 1ère classe”.

Applications to Matthias Cuntz (matthias.cuntz (at) should include a CV, the publication list, a letter of motivation, as well as telephone numbers and e-mail addresses of possible references. Applications will be accepted until the position is filled.

Welcome, Juan Carlos Zamora Pereira

Sumforest – ForRISK welcomes Juan Carlos Zamora Pereira as new Ph.D. student at the University of Freiburg, Germany. Juan Carlos received a Master in Management and Conservation of Tropical Forests and Biodiversity from the Tropical Agricultural and Higher Education Center (CATIE) in Costa Rica. He will work together with Marc Hanewinkel on the ForRISK Work Package 3 – Risk assessment, economic evaluation and development of optimized management strategies to adapt Norway spruce and silver fir forests to extreme drought events.
