- •
Responses of a mesophytic Tibetan grassland to extreme precipitation were simulated.
- •
Completely divergent responses for growing season, plant functional types and organs.
- •
Dominating species shift from sedges to forbs exaggerated grassland degradation.
- •
Synergistic effects of soil temperature and water content were key abiotic factors.
- •
Fairly high resilience contributed to the grassland acclimation and stability.
