AB Numerous ecological studies in grasslands and shrublands have used
   plant cover as a surrogate of aboveground net primary production
   (ANPP), biomass or biovolume. Regression equations between biomass and
   plant cover involve taking into account a wide range of vegetation
   cover. This comment assesses the consequences for biomass estimations
   of the method presented by Flombaum and Sala [Flombaum, P., Sala, O.E.,
   2007. A non-destructive and rapid method to estimate biomass and
   aboveground net primary production in and environments. journal of Arid
   Environments 69, 352-358.], which consists in removing portions of
   individuals to achieve the desired plant cover estimation. We found
   that alteration of architecture of individuals could lead to an
   overestimation of biomass by a factor ranging from 1.05 to 3.16,
   depending on the extent of the reduction of the plant cover. (C) 2008
