The Disc Pasture Meter (DPM) was first developed in New Zealand in the 1970s to estimate grass biomass in pastures. Its application was later extended to rangelands, where Bransby and Tainton adapted the method in 1977.
Veld condition assessments often require reliable information about the herbaceous grass layer, including species composition, basal cover, and fuel load. The disc pasture meter is a practical field tool designed to rapidly estimate standing grass biomass by measuring compressed pasture height using a weighted aluminium disc.
Its appeal lies in the ease of use and non-destructive nature, allowing repeated monitoring of pasture condition over time.
