Influence of hydrologic regime, vegetation, and land use on carbon dynamics of Northern Sierra Nevada fens, The
MetadataShow full item record
Fens are a type of wetland meadow supported by ground water and are important carbon reservoirs. However, many factors can impact these ecosystems. I measured water table dynamics, vegetation composition, CO2 fluxes, and impacts due to cattle trampling at four fens in the northern Sierra Nevada of California. My goal was to understand the natural functioning of fens and the effects of cattle grazing and drainage. Untrammeled areas were carbon accumulating while cattle trampling had a negative effect on carbon sequestration. Any amount of cattle trampling negatively affected carbon accumulation ...
