Xinghai longterm Vegetation Monitoring Site
Xinghai
From 04/2011Research focuses on long term effects of grazing on vegetation biomass and composition as well as on carbon cycling in the plant-soil system. For this five grazing exclosure plots and adjacent grazed areas along an altitudinal (3000-3600 m a.s.l.) and precipitation (375-505 mm) gradient, representing the common vegetation types of the upper montane belt on the Tibetan Plateau, are setup. Three sites are dominated by Kobresia spp and the two others in the drier region are dominated by grasses, mainly Stipa spp. For detailed site description see Miehe et al. (2008)
