The Assimilation and Retention of Carbon in Upland Heath Plant Communities Typical of Contrasting Management Regimes: A 13C Tracer Study

Table 1

Production estimates used for back calculating initial biomass from final biomass. Data are derived from annual production estimates from the literature with the exception of Calluna. For Calluna, the June and July production proportions [26] were applied to an annual estimate of production [27]. All data have been converted to g m−2 day−1.
