“…A common objective in coastal restoration is to provide diverse habitats for a diverse assemblage of waterbird species (Sebastián‐González & Green 2014). Creating optimal water depth and topographic gradients for interspecific differences in habitat can be beneficial (Guan et al 2016; Zou et al 2019; Dai et al 2021). Simultaneously, the changes in site topography and water level caused by the restoration project should be taken into account.…”

Coastal engineering poses a significant threat to the survival of migratory waterbirds worldwide. However, the mechanisms through which engineering affects waterbirds are still unclear. To gain a better understanding of this issue, we conducted a three‐year survey of waterbirds on Shanxinsha Island, which underwent restoration engineering, along the East Asian–Australasian Flyway. We compared the seasonal migratory change among different species groups through and after the island restoration engineering. We observed a total monthly maximum count of 118,506 individuals from 61 waterbird species over the span of 38 months, including eight globally threatened species and five species that exceeded 1% of the flyway population. Throughout the survey periods, the average number of total waterbirds and small shorebirds observed during the migrating season decreased by 52.7 and 48.6%, respectively. The massive loss of high‐tide roosting areas was the primary factor contributing to this decline. The combined effects of increased vegetation and deeper water levels resulted in a 38.8% reduction in exposed tidal flat area, as determined through land cover verification and fractional vegetation cover calculations. While tourism activities exhibited fewer negative consequences compared to island restoration engineering, they had a greater impact on small breeding shorebirds. Our study showed that small shorebirds were particularly susceptible to island restoration engineering, whereas large shorebirds and swimming birds were more flexible in their use of roosting or foraging sites. We suggest that the impact of future coastal engineering requires more detailed assessment and monitoring, especially for small migratory shorebirds.

“…Shorebirds are relatively unique with their annual long‐distance migrations that can include multiple sites across multiple continents. However, evaluations targeting shorebirds have been limited to assessing interventions at a single site (or several nearby sites) (e.g., Burger & Niles, 2013; Dai et al., 2021). Although valuable, evaluations at this scale are unlikely to capture overall population dynamics and are of limited utility to inform comprehensive strategies to reverse declines.…”

We evaluated the impact of a philanthropic program investing in the conservation of sites along the Pacific Americas Flyway, which spans >16,000 km of coastline and is used by millions of shorebirds. Using a quasi‐experimental, mixed methods approach, we estimated what would have happened to shorebird populations at 17 sites without the sustained and additional investment they received. Using the synthetic control method, we failed to find evidence of an overall effect across three outcome variables. Species‐ and site‐level effects were heterogeneous, with a few cases showing some evidence of a positive effect, including a site with a high level of overall investment. Results suggest six shorebirds are declining across the entire Flyway, including at many Latin American sites. However, the percentage of Flyway populations present at the sites has remained stable, with a greater percentage at the treatment sites (i.e., investment sites). Multiple mechanisms are possible for our results, including that investments have yet to mitigate impacts and negative impacts at other sites are driving declines at the treatment sites. A limitation of our evaluation is the sole focus on shorebird abundance and lack of data that prohibited the inclusion of other outcome variables. Monitoring infrastructure is now in place to design a more robust and a priori shorebird evaluation framework across the entire Flyway. With this framework, it will prove easier to prioritize limited dollars to result in the most positive conservation outcomes.This article is protected by copyright. All rights reserved

“…Efforts under the 2002 East Asian‐Australasian Flyway Partnership (https://www.eaaflyway.net) also could apply an explicit spatial subsidies approach to migratory pathway conservation. While China's coastal wetlands provide habitat for more than 240 migratory waterbird species (Zhang & Ouyang, 2019), the steady loss of these ecosystems in the country has “caused a dramatic decline in internationally shared biodiversity and associated ecosystem services” that have been estimated on the order of $US200 billion per year (Ma et al., 2014; Dai et al., 2021).…”

Using ecosystem services to identify inequitable outcomes in migratory species conservation

Biodiversity conservation efforts have been criticized for generating inequitable socio-economic outcomes. These equity challenges are largely analyzed as placebased problems affecting local communities directly impacted by conservation programs. The conservation of migratory species extends this problem geographically since people in one place may benefit while those in another bear the costs of conservation. The spatial subsidies approach offers an effective tool for analyzing such relationships between places connected by migratory species. Designed to quantify ecosystem services provided and received in specific locations across a migratory species' range-and the disparities between them-the spatial subsidies approach highlights three axes of inequity: between indigenous and settler colonial societies, between urban and rural populations, and between the Global North and Global South. Recognizing these relationships is critical to achieving two mutually reinforcing policy goals: avoiding inequitable conservation outcomes in efforts to conserve migratory species, and ensuring effective long-term conservation of migratory species. In demonstrating how the spatial subsidies approach enables the identification and quantification of inequities involving three migratory species (northern pintail ducks, monarch butterflies, andThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
