Emission of CO₂ and CH₄ From 13 Deadwood Tree Species Is Linked to Tree Species Identity and Management Intensity in Forest and Grassland Habitats

Abstract Deadwood is an important component of the global carbon cycle, and its decomposition releases dioxide (CO 2 ) methane (CH 4 into atmosphere. However, main drivers these greenhouse gas emissions from deadwood are not well understood. We investigated that govern CO CH emission rates 793 specimens 13 different tree species, which were exposed on 27 forest 38 grassland plots at Schorfheide‐Chorin (Germany) for one year. Tree species identity was driver both gases, whereas habitat type management intensity only rate. positively linked to mass loss one‐third higher in compared habitats. The wood traits organic extractives, lignin, sulfur content negatively associated with rates, carbon, nitrogen, magnesium showed opposite effect. Among climate variables, air humidity soil moisture habitats affected rates. a negative relationship increasing density types but related contents. Taken together, predicted by traits, climatic less predictable influenced differed those emissions. Our results provide deeper insight mineralization processes should be considered further cycle assessments.
