Evaluating MONICA's capability to simulate water, carbon and nitrogen fluxes in a wet grassland at contrasting water tables.

Wet grasslands, which are vital for water and nutrient regulation, are characterised by distinct water, carbon (C) and nitrogen (N) dynamics, and their interactions. Due to their shallow groundwater table, wet grasslands promote a strong interconnection between diverse vegetation and soil water. Researchers have investigated how wet grasslands respond to environmental changes, using various simulation models to understand how these sites contribute to water, C and N dynamics.

The unexpected long period of elevated CH emissions from an inundated fen meadow ended only with the occurrence of cattail (Typha latifolia).

Drainage and agricultural use transform natural peatlands from a net carbon (C) sink to a net C source. Rewetting of peatlands, despite of high methane (CH ) emissions, holds the potential to mitigate climate change by greatly reducing CO emissions. However, the time span for this transition is unknown because most studies are limited to a few years.
