Table 1 Inventory of tree species abundance (# ha−1) and aboveground biomass (AGB) from a 20 m radius from the center of the forest plots (extrapolated to one hectare, n = 6) sampled for CO2 and CH4 at the smallholder and tea estate sites, in the Mau forest region of, Kenya

From: Soil carbon dioxide and methane fluxes from forests and other land use types in an African tropical montane region
