Grass biomass and nitrogen data from carcass sites

Grass data collected at anthrax negative, plains zebra carcass sites one, two and three years after death. Samples were collected 1.5m (zone 1), 4.5m (zone 2) and 7.5m (zone 3) from carcass centers. Measurements include grass biomass (g/m^2) averaged across the two replicate quadrats sampled and grass nitrogen, measured as Kjeldahl N. NA values for nitrogen samples were of insufficient mass for analysis.
