- •
We conduct a long-term (6 years) and large scale grazing experiment.
- •
We test effects of grazing, environmental factors and species on grassland quality.
- •
Aboveground net primary productivity determine community forage nutritive yield.
- •
Dominant species are more important than species diversity.
- •
ANPP and species composition are the optimum indicators for guiding grassland management practices.
