Summary1. Plant litter is a key component in terrestrial ecosystems. It plays a major role in nutrient cycles and community organization. Land use and climate change may change the accumulation of litter in herbaceous ecosystems and affect plant community dynamics. Additionally, the transfer of seeds containing plant material (i.e. litter) is a widespread technique in grassland restoration. 2. Ecosystem responses to litter represent the outcome of interactions, whose sign and strength will depend on many variables (e.g. litter amount, seed size). A previous meta-analysis (from 1999) reported that litter had an overall negative effect on seed germination and seedling establishment in different ecosystems. However, recent studies indicated that this might not be the case in grassland ecosystems. 3. We used 914 data from 46 independent studies to analyse the effects of litter on seedling (i) emergence, (ii) survival and (iii) biomass, employing meta-analytical techniques. Each data set was stratified according to methodology, grassland type, irrigation conditions, litter amount and seed size. 4. We found an overall neutral effect of litter presence on seedling emergence and survival and a positive effect on seedling biomass. However, whereas for field experiments the response remained neutral, it was positive for common garden studies. In glasshouse experiments, litter effects were negative for emergence and positive for biomass. 5. Litter may have a positive effect on seedling recruitment in dry grasslands or under water-limited conditions, or in the presence of low to medium litter amounts (< 500 g m À2 ). However, high litter amounts (> 500 g m À2 ) will inhibit seedling recruitment. Large seeds showed a more positive response to litter presence with respect to seedling emergence and survival, but not concerning biomass. 6. Synthesis. Under dry conditions (e.g. dry grasslands or dry periods) or with low to medium litter amounts, litter presence has a positive effect on seedling establishment. However, climate and land use change may promote litter accumulation and reduce seedling establishment, affecting grasslands composition and ecosystem functions.

“…In recent years, intensive studies have presented the effects and protective benefits of PSC or grazing exclusion on aboveground vegetation succession and community structure (Courtois et al, 2004;Gibson et al, 2001;Herrera-Arrieta et al, 2011;Loydi et al, 2012;Pettit et al, 1995;Shapotou Desert Research Experiment Station, 1991;Zhang et al, 2004;Zhao et al, 2008). However, very little quantitative research has focused on the effects of PSC and grazing exclusion on soil chemical properties or the effectiveness of restoration methods, especially in areas subjected to different degrees of degradation.…”

“…The selection of the areas was based on 276 publications that described the size of the areas, their species richness and the presence of endemic taxa, genus or threatened species. Low forage allowance, or high stocking rates, was frequently reported as one of the main drivers of reduced grassland species diversity in the region (Chaneton and Facelli 1991, Altesor et al 1998, Ghersa and Leon 1999, Altesor et al 2005, Overbeck et al 2007, Loydi 2012. Other threats to floristic diversity were the invasion of exotic species, expansion of crop and ley areas and urbanisation (table 2).…”
