In recent years, due to rapid economic development, the Bohai Rim has become a focus of attention. The area abundant waterbird resources, however, coastal wetlands in are currently under serious threat and conservation needs be addressed urgently. Exploring changes main driving factors waterbirds conducting habitat suitability assessments for great significance regional ecology environmental protection efforts. this study, during period 2002–2021, we recorded numbers species region China. Then, quantified potential suitable habitats analyzed using MaxEnt model. results showed that richness around increased gradually over 20-year period, more were detected wetland than other habitats. Five hotspot regions require special attention, including Yellow River Delta Nature Reserve, Beidagang Wetland, Beidaihe National Wetland Park, Liaohe Estuary Caofeidian Park.

Achievements, challenges, and recommendations for waterbird conservation in China's coastal wetlands

Avian Research, Journal Year: 2023, Volume and Issue: 14, P. 100123 - 100123

Published: Jan. 1, 2023

China's coastal wetlands provide breeding, migration stopover, and wintering habitats for about 230 waterbird species, which is more than a quarter of all waterbirds in the world. Large-scale high intensity human activities have resulted serious loss degradation over past half century, causing population declines many waterbirds. Through literature review expert surveys, this article reviews conservation measures taken recent decades to conserve provides recommendations future action from three aspects: policy administration, habitat management, multiparty participation. Over decades, legislation, regulations plans at national level site-specific interventions been implemented, with notable improvement effectiveness making multi-stakeholder Accordingly, some threats mitigated key sites designated as strictly protected nature reserves. However, critical issues still remain, mostly related such wetland restoration, control invasive Spartina alterniflora, environmental pollution, artificial quality. We highlight that protecting natural tidal improving quality are waterbirds, especially those highly dependent on intertidal wetlands. China has demonstrated strong commitment ecological restoration future, terms both funding policies biodiversity ecosystems.

Effects of anthropogenic landscapes on population maintenance of waterbirds

Conservation Biology, Journal Year: 2021, Volume and Issue: 36(2)

Abstract Anthropogenic impacts have reduced natural areas but increased the area of anthropogenic landscapes. There is debate about whether landscapes (e.g., farmlands, orchards, and fish ponds) provide alternatives to habitat under what circumstances. We considered can mitigate population declines for waterbirds. collected data on trends biological traits 1203 populations 579 species across planet.

An emerging coastal wetland management dilemma between mangrove expansion and shorebird conservation

Conservation Biology, Journal Year: 2022, Volume and Issue: 36(5)

Published: Feb. 25, 2022

Abstract Coastal wetlands around the world have been degraded by human activities. Global declines in extent of important coastal wetlands, including mangroves, salt marshes, and tidal flats, necessitate mitigation restoration efforts. However, some well‐meaning management actions, particularly mangrove afforestation, can inadvertently cause further loss degradation other habitats if these actions are not planned carefully. In particular, there is a potential conflict between shorebird conservation because afforestation may occur at expense bare which form main foraging for threatened shorebirds support organisms. We examined several case studies that illustrate trade‐off flat maintenance. To investigate whether examples reflect an emerging broad‐scale problem, we used satellite imagery to quantify change habitat 22 areas mainland China from 2000 2015.The across all sites declined significantly ( p < 0.01, n = 22) while among with mangroves present, expanded 14).

Shorebirds-driven trophic cascade helps restore coastal wetland multifunctionality

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Dec. 6, 2023

Abstract Ecosystem restoration has traditionally focused on re-establishing vegetation and other foundation species at basal trophic levels, with mixed outcomes. Here, we show that threatened shorebirds could be important to restoring coastal wetland multifunctionality. We carried out surveys manipulative field experiments in a region along the Yellow Sea affected by invasive cordgrass Spartina alterniflora . found planting native plants alone failed restore multifunctionality experiment. Shorebird exclusion weakened multifunctionality, whereas mimicking higher predation before shorebird population declines excluding their key prey – crab grazers enhanced The mechanism underlying these effects is simple cascade, whereby control otherwise suppress recovery destabilize sediments (via bioturbation). Our findings suggest harnessing top-down of through habitat conservation, rewilding, or temporary simulation consumptive non-consumptive should explored as nature-based solution degraded wetlands.

Wetlands in the Bohai Sea Rim play an indispensable role maintaining stability of waterbird populations on East Asian-Australian flyway. However, motivated by economic development and urban expansion, coastal wetlands this region have been extensively reclaimed, leading to a decline area degradation natural over past two decades. We analyzed temporal spatial changes suitable habitats different groups waterbirds quantified habitat connectivity importance patches using Probability Connectivity.

Prioritizing landscapes for mitigating the impacts of onshore wind farms on multidimensional waterbird diversity in the Yellow Sea

Current Zoology, Journal Year: 2024, Volume and Issue: 70(6), P. 752 - 764

Abstract Ongoing wind energy developments play a key role in mitigating the global effects of climate change and crisis; however, they have complex ecological consequences for many flying animals. The Yellow Sea coast is considered as an bottleneck migratory waterbirds along East Asian–Australasian flyway (EAAF), also important farm base China. However, large-scale onshore farms EAAF on multidimensional waterbird diversity, how to mitigate these effects, remain unclear. Here we examined their surrounding landscapes affected diversity coast. Taxonomic, functional, phylogenetic assemblages, mean pairwise distances nearest taxon with null models were quantified relation 4 different turbine densities. We measured 6 landscape variables. Multi-dimensional (taxonomic, diversity) significantly decreased increasing density. Functional structures tended be clustered communities, environmental filtering drove community assemblages. Furthermore, was regulated by combination density variables, edge aquaculture ponds, addition density, having greatest independent contribution diversity. These results suggest that attempts impact could involve transformation regions, example, including high-edge-density ponds (i.e., industrial ponds) around farms, instead traditional low-edge-density ponds.
