摘要:
Species density and grass density were measured using a small‐quadrat method in eight plant communities in the Nylsvley Nature Reserve, South Africa. The presence of new species in each additional quadrat was used to calculate sample size. A sample size of 20 quadrats of 0.25 m2per site was found to be sufficient to measure species richness and density, and grass density in most plant communities in Mixed Bushveld. A sample size of approximately 30 quadrats was found to be necessary to survey plant communities with a relatively high species richness.
