Published: April 29, 2024

Planting has been widely adopted to battle the loss of salt marshes and establish living shorelines. However, drivers success in marsh planting their ecological effects are poorly understood at global scale. Here, we assemble a database, encompassing 22,074 observations reported 210 studies, examine impacts planting. We show that, on average, 53% plantings survived globally, plant survival growth can be enhanced by careful design sites, species selection, novel planted technologies. enhances shoreline protection, primary productivity, soil carbon storage, biodiversity conservation fishery production (effect sizes = 0.61, 1.55, 0.21, 0.10 1.01, respectively), compared with degraded wetlands. ecosystem services marshes, except for have not yet fully recovered natural wetlands size -0.25, 95% CI -0.29, -0.22). Fortunately, levels most functions related climate change mitigation increase plantation age when wetlands, achieve equivalence after 5-25 years. Overall, our results suggest that could used as strategy enhance sequestration.

Fire-driven disruptions of global soil biochemical relationships

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 30, 2025

Fires alter the stability of organic matter and promote soil erosion which threatens fundamental coupling biogeochemical cycles. Yet, how biogeochemistry its environmental drivers respond to fire remain virtually unknown globally. Here, we integrate experimental observations random forest model, reveal significant divergence in responses attributes fire, including carbon (C), nitrogen (N), phosphorus (P) contents worldwide. Fire generally decreases C, has non-significant impacts on total N, while it increases inorganic N P, with some effects persisting for decades. The are most strongly negative cold climates, conifer forests, under wildfires high intensity frequency. Our work provides evidence that decouples globally helps identify high-priority ecosystems where critical components especially unbalanced by is management a world subjected more severe, recurrent, further-reaching wildfires.

Plant species, inundation, and sediment grain size control the development of sediment stability in tidal marshes

Ecological Applications, Journal Year: 2025, Volume and Issue: 35(1)

Published: Jan. 1, 2025

Abstract Tidal marshes can contribute to nature‐based shoreline protection by reducing the wave load onto shore and erosion of sediment bed. To implement such requires ability quickly restore or create highly stable erosion‐resistant tidal at places where they currently do not yet occur. Therefore, we aim identify drivers controlling rate which stability builds up in young pioneer marshes. Sediment proxies were measured over age gradients spanning 18 years six marsh sites Western Scheldt estuary (SW Netherlands): Three dominated Spartina anglica , a densely growing species, three Scirpus maritimus less species. Our results showed that presence increased shear strength compared unvegetated flat, while did not. This difference may be related contrasting clonal expansion strategies root densities these two increase further beyond 6 coverage implying observed effect on occurs fast (<6 years). Furthermore, often with decreasing inundation duration water content. study shows order beds future restoration projects, should vegetated well‐draining, cohesive sediments relatively high intertidal elevation.

Ecosystem services (ESs) are essential for balancing environmental sustainability and socio-economic development. However, the of ESs their relationships increasingly threatened by global climate change intensifying human activities, particularly in ecologically sensitive agriculturally-intensive regions. The Songnen Plain, a crucial agricultural region Northeast China, faces considerable challenges sustaining its due to overexploitation land, degradation, variability. This study assessed five key Plain from 2000 2020 across multiple scales: habitat quality (HQ), soil conservation (SC), water yield (WY), food production (FP), windbreaking sand fixing (WS). We evaluated trade-offs synergies between these ESs, as well driving factors main ES trade-offs. Our findings indicate that provisioning (WY FP) regulating (SC WS) improved over time, with FP exhibiting most significant increase at 203.90%, while supporting (HQ) declined 32.61%. primary ecosystem service multifunctionality areas were those provided FP, SC, WY, accounting 58% total. varied spatial scales, stronger being observed pixel scale more pronounced county scale.
