Herbivory limits success of vegetation restoration globally

Science, Journal Year: 2023, Volume and Issue: 382(6670), P. 589 - 594

Published: Nov. 2, 2023

Restoring vegetation in degraded ecosystems is an increasingly common practice for promoting biodiversity and ecological function, but successful implementation hampered by incomplete understanding of the processes that limit restoration success. By synthesizing terrestrial aquatic studies globally (2594 experimental tests from 610 articles), we reveal substantial herbivore control under restoration. Herbivores at sites reduced abundance more strongly (by 89%, on average) than those relatively undegraded suppressed, rather fostered, plant diversity. These effects were particularly pronounced regions with higher temperatures lower precipitation. Excluding targeted herbivores temporarily or introducing their predators improved magnitudes similar to greater achieved managing competition facilitation. Thus, herbivory a promising strategy enhancing efforts.

Variation of biomass carbon stock within agroforestry systems in the Senegalese groundnut basin

Discover Sustainability, Journal Year: 2024, Volume and Issue: 5(1)

Published: March 14, 2024

Abstract Agroforestry plays a pivotal role in mitigating greenhouse gas (GHG) emissions and addressing the challenges posed by climate change. While carbon sequestration efforts have primarily centred on forests, it is imperative to acknowledge contribution that non-forest ecosystems, such as agroforestry, can offer. This study investigated influence of agroforestry systems variation biomass stocks Sahelo-Sudanian Sudanian regions Senegalese Groundnut basin. Three primary were studied: silvopastoral, agrisilvicultural, agrosilvopastoral. Forty-six (46) 100 m × plots sampled, within which 1 2 subplots used sample understory across three two climatic zones. Analysis variance was performed assess zones stocks. The findings showed region, agrisilvicultural system exhibited highest AGC + BGC stocks, averaging 43.42 ± 21.61 tCha −1 . In contrast, silvopastoral significantly higher amounted 36.33 12.27 region. On other hand, (p < 0.01) agrosilvopastoral than both had significant effect Nevertheless, less pronounced when comparing regions. These results underscore importance specific land management practices interacting with local conditions Therefore, policy makers should carefully consider interaction these factors implementing planning mitigation strategies West Africa.

Effects of different grazing intensities on plant species diversity at different spatial scales in a desert steppe in Inner Mongolia

PeerJ, Journal Year: 2025, Volume and Issue: 13, P. e19087 - e19087

Published: March 19, 2025

The effect of grazing intensity on plant diversity has been widely studied. In this study, desert steppes with different intensities (no (CK), light (LG), moderate (MG), heavy (HG), and extremely (EG)) in Inner Mongolia were selected to study the changes species at spatial scales (α, β, γ diversity) α groups (dominant species, common rare species).The results showed that α, first decreased then increased increasing intensity, β was observed be most sensitive index intensity. Grazing had greatest impact least species. Therefore, are great significance for maintenance assessment biodiversity. We concluded leads a response diversity, phenomenon is mainly affected by could provide scientific bases protection sustainable steppes.

Gridded Grazing Intensity Based on Geographically Weighted Random Forest and Its Drivers: A Case Study of Western Qinghai–Tibetan Plateau

Land Degradation and Development, Journal Year: 2024, Volume and Issue: 35(17), P. 5295 - 5307

ABSTRACT Overgrazing affects the grass‐livestock balance and endangers grassland ecological security. Despite extensive studies conducted on identifying quantifying grazing intensity, there is still room for improvement in research gridding particularly areas with limited data Qinghai–Tibet Plateau. Therefore, we proposed a intensity spatialization method using geographically weighted random forest (GWRF) to gain further insights into spatial heterogeneity of alpine intensity. This incorporates multiple remote sensing related human activities natural factors, as well annual livestock statistics at township level over several years, while adequately considering autocorrelation Additionally, employed Lindeman Merenda Gold (LMG), geographical detector model, structural equation model (SEM) assess contribution influence path driving factors We also utilize partial correlation analysis dual‐phase mapping examine impact distribution The results demonstrate that GWRF‐based accurately predicts by demonstrating its consistency township‐scale ( R 2 = 0.92 p < 0.01), RMSE 1.07). provides valuable technical support pastoral availability. evaluate trends observe an increase Gar Purang counties.
