Dual threat of tidal flat loss and invasive Spartina alterniflora endanger important shorebird habitat in coastal mainland China

Journal of Environmental Management, Journal Year: 2020, Volume and Issue: 278, P. 111549 - 111549

China's coastal wetlands are critically important to shorebirds. Substantial loss of tidal flats, shorebirds' primary foraging grounds, has occurred from land claim and other processes, is driving population declines in multiple species. Smooth cordgrass Spartina alterniflora was intentionally introduced the coast China 1979 promote conversion flats into dry since spread rapidly. The occurrence S. reduces availability roosting habitat for shorebirds, may be particularly detrimental places that have experienced flat loss. However, extent which encroaching upon shorebird throughout mainland China, its intersection with loss, not been quantified. Here, we i) estimate change spatial between 2000 2015 where internationally numbers shorebirds recorded; ii) map coverage at same set sites; and, iii) investigate these two threats intersect. Our analysis remote sensing data indicated a 15% net area across all sites, including 39 53 individual sites (74%). 28 (53%) 2015, 22 (79%) also had 2015.

The State of Migratory Landbirds in the East Asian Flyway: Distributions, Threats, and Conservation Needs

Frontiers in Ecology and Evolution, Journal Year: 2021, Volume and Issue: 9

Published: April 13, 2021

With nearly 400 migratory landbird species, the East Asian Flyway is most diverse of world’s flyways. This diversity a consequence varied ecological niches provided by biomes ranging from broadleaf forests to arctic tundra and accentuated complex biogeographic processes. The distribution migration ecology landbirds still inadequately known, but recent explosion in number studies tracking raptors, cuckoos, kingfishers passerines has greatly increased our knowledge about stopover wintering many routes that link northeast Eurasia tropics. Yet also supports highest threatened species among Strong declines have been detected buntings (Emberizidae) other long-distance migrants. While conservation this region largely focused on unsustainable hunting, there are threats, such as habitat loss agro-chemical use driven directly land cover change climate-related Important gaps be addressed include (1) threats affecting different parts their annual cycle, (2) range-wide population trends, (3) requirements during non-breeding season, (4) status critical sites (including understudied farming landscapes, rice fields) bottlenecks along flyway.

Satellite derived coastal reclamation expansion in China since the 21st century

Global Ecology and Conservation, Journal Year: 2021, Volume and Issue: 30, P. e01797 - e01797

Published: Sept. 6, 2021

Since 2000, many coastal land reclamation projects have been implemented in China to alleviate the shortage of resources with rapid urban sprawl and economic growth. As a result, both length proportion artificial shoreline increased significantly. Meanwhile, inevitably brings some negative environmental ecological issues, such as biodiversity loss, water pollution, wetland degradation. In this study, based on GlobeLand30 product OpenStreetMap coastline data, we tracked expansion 21st century. Specifically, analyzed intensity types all provinces China, explored relationship between GDP growth understand status areas during 2000–2020. Our results showed that total area reclaimed along coast was 5135.31 km2, which aquaculture were two main land-use/land-cover (LULC) types, accounting for 71.89% area. Among provinces, Tianjin exhibited greatest (i.e., 7.16 km2 km−1) Zhejiang Province had largest 1304.65 km2). We also found positive correlation development reclamation. addition, progress activities has greatly slowed down owing national policies released recent years.

Satellite and GPS tracking technology continues to reveal new migration patterns of birds which enables comparative studies strategies distributional information useful in conservation. Bar‐tailed godwits the East Asian–Australasian Flyway Limosa lapponica baueri L. l. menzbieri are known for their long non‐stop flights, however these populations steep decline. A third subspecies this flyway, anadyrensis , breeds Anadyr River basin, Chukotka, Russia, is morphologically distinct from based on comparison museum specimens collected breeding areas. However, non‐breeding distribution, route population size entirely unknown.

The conservation of Afro‐Palaearctic migrants: What we are learning and what we need to know?

The global long‐term decline of migrant birds represents an important and challenging issue for conservation scientists practitioners. This review draws together recent research directed at the Afro‐Palaearctic flyway considers its implications conservation. greatest advances in knowledge have been made field tracking. These studies reveal many species to be highly dispersed non‐breeding season, suggesting that site‐level a small number locations will almost certainly limited value most species. Instead, widespread but ‘shallow’ land‐sharing solutions are likely more effective but, because any local changes Africa affect European populations, impact extremely difficult detect through monitoring breeding grounds. Targeted action boost productivity Europe may help halt declines some reversing is also require these approaches areas. retention or planting native trees humid arid zones within generic tool, especially if concentrated on favoured tree Overall, despite growing knowledge, we remain largely unable progress beyond general flyway‐level actions, such as maintaining suitable habitat across increasingly anthropogenic landscape generalists, targeted site‐based specialists stop‐over sites, protection from hunting, individual species‐level solutions. We assess cost‐effectiveness specific action, mainly uncertainty around how populations affected by conditions during passage grounds, well efficacy implementation particularly For develop implement conservation, scientific need better integrated with each other implemented full annual cycle.
