Summary: Globally, tidal flats are becoming narrower due to reclamation and sea level rise. The impact of tidal flat narrowing (TFN) on tidal creek systems is not well understood. This study investigated the response of tidal creek systems in the central Jiangsu coast, China, to TFN using the quantification and mapping of tidal creek ecosystem vitality (TCEV). The results showed a significant loss of tidal flats and a decline in TCEV, indicating the need for ecological restoration and controlling reclamation.

Summary: This study investigates the impact of reclamation on the coastal wetland system in Jiangsu, China, from the perspective of ecosystem services stability. It quantifies the impact of tidal flat reclamation on ecological stability and its cumulative effects using a stability deviation index. The results show that reclamation has a significant impact on the ecosystem stability of the coastal tidal flat area. The study provides ideas for analyzing the comprehensive impact of reclamation on coastal wetland ecosystems and guidance for the efficient utilization and protection of tidal flats.

Summary: Reclamation is a significant anthropogenic activity that affects tidal flat morphology and ecosystem services. Different types of reclamation, such as upper-flat enclosure and lower-flat enrockment, can induce morphological adjustments on tidal flats, leading to different evolutionary directions. The choice of reclamation types in practices is potentially influenced by tidal range and sediment supply.

Summary: This study highlights the importance of considering the status of regional ecosystem services supply and demand in large-scale spatial planning for tidal wetland restoration. The authors developed a five-step workflow based on systematic conservation planning to identify priority areas for restoration and applied it to coastal reclaimed areas in Shanghai, China. The findings showed that the potential restorable areas accounted for only 31.4% of the original reclaimed area, and considering ecosystem services demand resulted in an increase in priority areas and a higher restoration cost.

Summary: Reclamation of tidal flats is a common method used in coastal areas to expand land area and develop the economy. This study investigates the impacts of reclamation on tidal and suspended sediment dynamics using numerical modeling in the Oufei tidal flat at the Wenzhou coast. The results show that reclamation reduces the tidal flat area, weakens tidal currents, and reduces suspended sediment concentration. The construction of the Oufei dike also alters sediment circulation and enhances landward sediment transport inside the estuary. The findings of this study can be used as a reference for analyzing suspended sediment transport in other sites affected by tidal flat reclamation.

Summary: This study synthesizes 120 studies from five continents and finds that forest restoration can promote multiple dimensions of biodiversity and ecosystem function across different climates and forest types. However, predicted climate changes may constrain the positive effects of forest rewilding, and tradeoffs exist in very old forests between biodiversity and ecosystem function.

Summary: Tidal wetlands play a crucial role in global carbon cycling, but their greenhouse gas monitoring and predictions face challenges due to spatial heterogeneity and tidal flooding. This study used eddy covariance and chamber measurements to quantify CO2 and CH4 fluxes in a restored tidal saltmarsh. The results showed that the wetland acted as a net sink for CO2 and a small net source of CH4. The study also highlighted the importance of wetland plant community, elevation, and inundation in influencing carbon fluxes. Future research should focus on incorporating high-resolution imagery, automated chambers, and quantifying carbon export in tidal waters.

Summary: Because of continuous coastal development, it is important to analyze the impact of persistent topographic changes. This study used an ocean model to simulate tidal changes in response to gradual reclamation in the East China and Yellow Seas. The results showed that persistent man-made reclamation can cause significant regional tidal changes through tidal energy redistribution and modification.

Summary: The study revealed varying levels of accessibility to different salmon species in intertidal wetlands, with Chum Salmon having more stable opportunities compared to Chinook Salmon and Coho Salmon. Inundation in wetlands fluctuated nonlinearly with tidal height, and fish were able to access the productive marsh edge for approximately 40-50% of the time during out-migration periods. The fish habitat opportunity index provided a realistic metric for assessing fish habitat opportunity and could aid resource managers in predicting the relative effects of restoration efforts on habitat opportunity for juvenile anadromous fishes.

Summary: Coastal tidal flats have gained attention due to their role in directly releasing terrestrial microplastics into the ocean. Reclamation activities on these flats are increasing, but their environmental impact is still unclear. This pioneering study assessed the emission characteristics of microplastics from reclamation geotextiles and conducted a risk assessment. The research found that coastal reclamation areas store a high concentration of microplastics, contributing to marine microplastic pollution.

Summary: This study focuses on evaluating the initial performance of a constructed upland-peatland complex in the Athabasca Oil Sands Region in Canada. The results show that the peatland quickly evolved from a carbon source to a carbon sink, and the establishment of vegetation and a well-connected groundwater network contributed to the system's self-sustainability and carbon accumulation.

Summary: Tidal flat areas, important for land development, are also becoming receivers of antibiotic resistance. The study found various antibiotics and antibiotic resistance genes in soils and sediments, with significant positive correlations observed between certain antibiotics and their corresponding resistance genes. Additionally, heavy metal pollution may enhance the effects of antibiotic resistance genes. Livestock farming and aquaculture contribute the most to antibiotic resistance in coastal areas.

Summary: This study compares different methods for extracting species-level wetland vegetation information, using statistical features, temporal features, and phenological features. The results show that the harmonic model is more effective for obtaining phenological characteristics of wetland vegetation, combining the three features provides the highest overall accuracy in classification, and phenological features have the greatest impact on classification. The mapping results across all seasons yielded the most accurate classification.

Summary: This study examined the public value of the restoration plan for the Gomsoman Tidal Flat in South Korea. The average willingness to pay per household was estimated to be KRW 3170 (USD 2.7) per year, with a national value of KRW 63.3 billion (USD 53.9 million). The benefits of the plan outweigh the costs involved, making it a worthwhile endeavor.
