Hi Amiel, I would recommend the comparative yield (CY) method for non-destructive biomass sampling. The following citation provides an overview of the methodology. Several of my colleagues have used the technique for effective long-term sampling in rangeland systems.

I would be happy to provide more resources if need be. Many thanks, *Jessica P.
