Roger Grau-Andrés
Ecosystem ecologist studying vegetation effects on carbon cycling in boreal forests

Presentation

I am an ecologist with a background in fire behaviour and fire ecology research in peatlands and heathlands, and bryophyte ecology in wetlands. At SLU, I study the impact of altered vegetation composition on carbon cycling, the effect of changes in precipitation regimes on forest floor and bryosphere carbon cycling and on bryosphere fauna, the effects of the bryosphere on decomposition in boreal forest floors, and the impact of biochar soil amendment on tree biomass and on forest floor greenhouse gas emissions in production forests.
