  1. 1Models = Two models; Model 1 uses SAGBbuffer as fixed effects with plot identity as random effect. Model 2 uses MAGBbuffer with plot identity as random effect (see text).
  2. 2SAGBbuffer = Ratio of either sum of AGB at the buffer to the ground reference AGB per hectare, MAGBbuffer = ratio of Maximum AGB at the buffer to the ground reference AGB per hectare (see text).
