# Plant litter loss exacerbates drought influences on grasslands [https://doi.org/10.5061/dryad.sf7m0cgcb](https://doi.org/10.5061/dryad.sf7m0cgcb) This dataset includes pre-treatment plant community and soil properties, plant and soil responses to litter removal treatment from 2015 to 2021, changes in stability in terms of plant species and functionl group composition, species richness, asynchrony of species and functional group, and aboveground primary production (ANPP). ## Description of the data and file structure trt: -50%=50% litter removal -100%=100% litter removal Litter\_amount= Litter removal amount（g m-2) GST= Growing season soil temperature(ºC) NGST= Non-growing season soil temperature (ºC) SM= Soil moisture (v/v,%) SIN=Soil inorganic nitrogen (mg kg-1) Nmin= Net nitrogen mineralization rate (mg N kg-1 d-1) LRR=Log response ratio LRR\_ANPP=Ln(ANPPdrought/ANPPpredrought) Ln(ANPPpost-drought/ANPPpre-drought) Similirity=Community composition similarity to pre-drought Abundance\_PB= Abundance of perennial bunchgrass species (per m-2) Abundance\_PR= Abundance of perennial rhizomatous graminoids species (per m-2) Abundance\_PF= Abundance of perennial forb species (per m-2) Abundance\_AF= Abundance of annual forb species (per m-2) relative\_Abundance\_PB= Realative abundance of perennial bunchgrass species (%) relative\_Abundance\_PR= Relative abundance of perennial rhizomatous graminoids species (%) relative\_Abundance\_PF= Relative abundance of perennial forb species (%) relative\_Abundance\_AF= Relative abundance of annual forb species (%) ANPP\_PB= ANPP of perennial bunchgrass species (g m-2) ANPP\_PR= ANPP of perennial rhizomatous graminoids species (g m-2) ANPP\_PF= ANPP of perennial forbs species (g m-2) ANPP\_AF= ANPP of annual forb species (g m-2) Height\_PB= Perennial bunchgrass species height (cm) Height\_PR= Perennial rhizomatous graminoids species height (cm) Height\_PF= Perennial forb species height (cm) Height\_AF= Annual forb species height (cm) Richness\_PB= Richness of perennial bunchgrass species (sp.m-2) Richness\_PR= Richness of perennial rhizomatous graminoids species (sp.m-2) Richness\_PF= Richness of perennial forb species (sp.m-2) Richness\_AF= Richness of annual forb species (sp.m-2) STN= Soil total nitrogen (g kg-1) SOC= Soil organic carbon (g kg-1) Asynchrony\_species= Species asynchrony Asynchrony\_FGs= Functional groups asychrony meanANPP= Average ANPP of community (g m-2) sdANPP= Standard deviation of ANPP Compositional\_stability= Community compositional stability Stability=Communtiy temporal biomass stability Stability\_PB= Perennial bunchgrass species stability Stability\_PR= Perennial rhizomatous graminoids species stability Stability\_PF= Perennial forb species stability Stability\_AF= Annual forb species stability Stability\_species= Species stability Stability\_FGs= Functional groups stability PCA= Principal component analysis Soil\_PCA1= PC1 of ST, NST, SM,Nmin and STN ## Sharing/Access information * The dataset are available at [https://doi.org/10.5061/dryad.sf7m0cgcb](https://doi.org/10.5061/dryad.sf7m0cgcb) ## Code/Software
