Abstract
Aboveground living plant-based methane (CH4) processes and fluxes have gained increasing attention over the last decades. However, aboveground living plant-based CH4 production and its quantities in terrestrial ecosystems are not well known. For profoundly understanding the CH4
processes and fluxes, we need to clarify aboveground living plant-based CH4 production and evaluate its quantities in terrestrial ecosystems. The vertical pattern (from rhizosphere to canopy of plants, and vice versa) of the CH4 production shows prominent variability across the various types of vegetated ecosystems, with especially large uncertainties in forests, and may moderately influence the vertical patterns of living plant-based CH4
oxidation and emissions. Aboveground living plant-based CH4 can be produced by microbial and non-microbial mechanisms. Microbial CH4 is primarily produced in wet vegetation niche, while non-microbial CH4 is typically produced in plant foliage under environmental stressors. The global aboveground living plant-based CH4 production is summarized at the quantities of about 2.26 (1.11-3.87) Tg CH4yr-1, and their uncertainties and complexities are further discussed. We suggest that aboveground living plant-based CH production and its relationships with aboveground living plant-based CH4 transport and emissions require more research, particularly within forest ecosystems.
