Abstract

Grasslands play an important role in carbon sequestration. Different management regimes may change the species composition of plants in grasslands, thus may affect the carbon sequestration potential. Therefore, we investigated if short-term changes in species composition occurred in response to shift in grazing to mowing in a semi-arid grassland in Hungary (Bugac). Species abundances were recorded as frequencies of species in cont iguous 5 cm quadrates along six (5 meters long) permanent transects at adjacent grazed and mowed sites in the spring and fall of 2012. High variation of vegetation characteristics was found within the management units at patch scale (at few m scale). The species richness, relative abundance of species, species density, Shannon diversity index, and forage quality differed among transects; however, no differences were observed between the two managements regimes at site scale (at hectar scale) (ANOVA, p;0.05). The average species abundance of the grazed and mowed sites were very similar (Poa spp.: 13.48;5.34%, 14.67;6,9%; Carex spp.:12.46;8.75%, 14.24;10.16%; Cynodon dactylon: 10;8.52%, 16.01;3.49%., respectively). Our results suggest that species composition differences can not be the main factors explaining short-term differences in carbon sequestration in natural semiarid grasslands.
