Benjamin Forsmark
My research focuses on how forests respond to environmental changes and management decisions. For temperate and boreal forests, these responses depend heavily on the availability of soil resources, notably water and nitrogen, and I work with different field experiments to understand how trees and soil organisms respond to changes in climate and nutrient availability, and how their interactions influence the carbon balance of forests.


I supervise thesis projects on forest soil, regeneration, mycorrhiza, carbon sequestration, nutrient and water cycling.
