Shrublands pose particularly difficult challenges for primary production measurement because of the complex structure of the vegetation. Classical approaches are described, including dimension analysis and the difference method both of which rely on destructive sampling and allometric relationships. A new spatially-explicit sampling approach and other procedures for optimizing sampling intensity are explained. Additional methodological considerations, including leaf habit and herbivory, also must be carefully evaluated to obtain reliable primary production estimates in shrubland ecosystems.

Keywords: allometry; dimension analysis; herbivory; difference method; leaf habit
