Abstract Protected areas form the backbone of global conservation efforts. Vegetation is primary foundation for achieving goals, and soil seed banks a cryptic biodiversity reservoir recruiting species that may not be represented in above‐ground vegetation. Unfortunately, unmanaged grazing by wild herbivores has led to vegetation degradation semi‐arid arid regions. However, experimental evidence on long‐term impacts largely lacking. Here, with aim examining how impact banks, we investigated composition germinable three protected (Yathong, Mungo Boolcoomatta) along precipitation gradient south‐eastern Australia. The density richness increased increasing aridity, which indicated regions an important reservoir. effects were strongly dependent precipitation. Wild disrupted at most site but promoted accumulation seeds least site. Grazing was linked increase frequency introduced decrease perennials. Synthesis applications : Disruption could lead failure post‐rain pulses growth hamper efforts restore areas. Therefore, suppressing herbivore numbers strategy enhance bank reserves revegetation

The world’s grasslands are under increasing threat of degradation. Given the potential for multiple drivers decline, precise diagnosis degradation is best achieved by comparison with a local, sustainable grassland community. Comparisons this kind becoming increasingly common regional plant communities, but these studies largely overlook interactions between soil responses to system and effective functioning seed bank. Surveys have revealed that only around 5% include information on bank composition no one aspect community structure features across all studies. Furthermore, majority provide ground coverage, sward biomass or species diversity in subcommunity, very few including health how changes environment could drive further deterioration size, We consider likely exacerbate rather than mitigate impacts function, leading spiral absence timely targeted intervention. propose improvements future seeking diagnose quantify

Close-to-nature restoration of mining areas is becoming widely recognized for its promotion ecosystem resilience and risk mitigation biodiversity losses. Soil seed banks can serve as a direct source natural restoration, well buffer against environmental changes in vulnerable ecosystem. However, arid area, it remains unclear how the anthropogenic disturbances affect what potential vegetation restoration. We conducted field study to investigate variation aboveground plant communities along disturbance gradient an opencast area desert northwestern China. Furthermore, we detected influence path on bank density richness at different layers. The had considerable density, with persistent accounting 46%. no significant differences none-to-moderate but decreased significantly severe level. Meanwhile, among all levels highest value mild There were low similarities between soil vegetation, their species composition was distinctly different. reduced directly. Besides, indirectly shallow layer via negative impact silt content. In contrast, transient mainly positive effect vegetation. Briefly, mild-to-moderate limited effects region. Our highlights supplementary indicator reflect ecological degradation significance recovery. results could be useful protection management projects areas.

Grassland ecosystems are among the largest terrestrial in China, and grazing, as an important grassland management method, has direct indirect impacts on ecosystems. Meta-analyses can be used to systematically evaluate summarize multiple findings from existing studies, but there have been few comparisons of meta-analysis methods. In this review, we effects grazing plants soil studies China 38 papers. The results show that they consistent conclusions, such reduces aboveground biomass by approximately half, increases pH, decreases C:N:P ratio, number topsoil microorganisms, conclusions light moderate index changes vary greatly study study. belowground was generally found increase, it slightly decreased some cases, total decreased, increased other cases.

We suggest subsequent meta-analyses should further clarify classification compare scales. Additionally, standardized network analyses recommended field manipulation experiments improve accuracy reduce temporal spatial limitations data.

Abstract Soil seed banks are the main reservoirs globally and critical for regeneration of grassland plant populations. Grazing often affects density diversity soil banks; however, it is not clear how these effects vary on a global scale with grazing intensity, duration, climatic conditions. Here, we screened 92 independent published articles performed meta-analysis extracted data. The four bank indices were analyzed. Four alpha indices, namely Shannon–Wiener, Margalef, Pielou, Simpson selected in this study. Shannon–Wiener index reflects species complexity community. Margalef richness bank. Pielou whether number seeds all evenly distributed, Simpson’s status dominant plants We found that significantly decreased total banks. Perennial more affected by than annual Heavy banks, while moderate index. Long-term (>10 years) had greatest impact index, medium-term (5–10 significant negative indices. In addition, our results show has greater effect arid areas those temperate areas. Knowledge climate-specific will contribute to understanding risk local extinctions populations help decision-makers maintain health ecosystems.
