I used a disc pasture meter on the ridge of a mountain (Goldreef Bushveld habitat). I came across a problem with the rocky conditions and the settling height of the disc, which in my opinion, skewed the results I obtained. Although I was measuring grass, the underlying rocks often determined where the disc settled. Surely this method would then not be useful in rocky environments? Has anyone else ever had a similar problem with using the disc pasture meter in rocky environments? Do you have any suggestions on how to use this data? Perhaps rather than using the calibration equation, an approximate value could be used as an index, however, this value would still not be totally representative of grass biomass. Any ideas or thoughts would be appreciated.
