Plant Biomass in the Extensive Sites

Above-ground plant biomass collected at grassland, switchgrass and corn sites on the GLBRC Extensive Site network. At each site, standing plant biomass was clipped to the ground and surface litter was collected from a measured area (see protocol). Biomass was sorted into broad groups: corn ears, corn stalks, switchgrass, big bluestem, indiangrass, other grass, forbs and surface litter. Biomass was dried and weighed. Robel pole measurements were also taken at each site to correlate to biomass.

This datatable is part of the GLBRC Extensive Sites dataset. This research is part of the broader investigation of the implications of cellulosic biofuel production on biodiversity, including beneficial microbes and insects as well as birds of conservation interest.
