“…Previous reviews ( 9 , 14 , 15 ) of translocation and social attraction for seabirds and other taxa provided insights on likely factors associated with positive outcomes, such as habitat quality, predator management, monitoring capacity, and other ecological factors, which align with this study. Life history strategies among seabird groups also influenced the methods and outcomes of active restoration ( 39 ). For example, Charadriiformes (gulls, terns, and auks) were strong candidates for active restoration with the highest predicted breeding outcomes, often achieved quickly, particularly when implemented on artificial habitats where managers can manipulate habitat and control threats, such as from predation or flooding.…”

“…Nearly 20% of events targeted 49 Procellariidae species, representing 51% of this globally threatened seabird family ( 35 ). While social attraction was frequently used, 49% of all translocations targeted this family, often alongside social attraction which can be operational for many years at relatively low costs even after a translocation is completed ( 39 ). As with Laridae, Procellariidae breeding response rate was high (79%), but took longer to initiate (5 y on average), consistent with their delayed onset of breeding (2 to 8 y to begin breeding) ( 50 ).…”

“…While one-third of all seabird species were targets of active restoration, we observed a bias in the concentration of these efforts: 56% of events targeted just 12 species, primarily terns, and 16% of events targeted globally threatened species, representing just 39% of all globally threatened seabirds. There is significant need and opportunity to apply active seabird restoration to more taxa, particularly threatened species, and across more geographies, including cases of assisted migration where current and historical colonies will no longer be viable under future climate scenarios ( 39 ).…”

“…Social attraction involves mimicking a breeding colony using visual, olfactory, and/or auditory cues to signal suitable breeding conditions, which often lures young seabirds that are prospecting (selecting) nest sites for the first time ( 40 , 55 ). When existing colonies of a target seabird are too far from restoration sites for breeders to be attracted, translocation often becomes necessary, particularly for species with high natal philopatry ( 32 , 39 ). Translocation involves physically moving seabirds, typically chicks, from one location to another, and caring for them until they fledge, with the goal of the chicks returning to form a colony when they reach breeding age.…”

“…With either method, restoration sites are typically identified based on habitat suitability, potential for threat reduction, the history of seabird breeding, and accessibility by practitioners. Artificial nests (especially underground burrows) can often supplement social attraction and translocation projects ( 39 , 56 ).…”

The global loss of biodiversity has inspired actions to restore nature across the planet. Translocation and social attraction actions deliberately move or lure a target species to a restoration site to reintroduce or augment populations and enhance biodiversity and ecosystem resilience. Given limited conservation funding and rapidly accelerating extinction trajectories, tracking progress of these interventions can inform best practices and advance management outcomes. Seabirds are globally threatened and commonly targeted for translocation and social attraction (“active seabird restoration”), yet no framework exists for tracking these efforts nor informing best practices. This study addresses this gap for conservation decision makers responsible for seabirds and coastal management. We systematically reviewed active seabird restoration projects worldwide and collated results into a publicly accessible Seabird Restoration Database. We describe global restoration trends, apply a systematic process to measure success rates and response times since implementation, and examine global factors influencing outcomes. The database contains 851 active restoration events in 551 locations targeting 138 seabird species; 16% of events targeted globally threatened taxa. Visitation occurred in 80% of events and breeding occurred in 76%, on average 2 y after implementation began (SD = 3.2 y). Outcomes varied by taxonomy, with the highest and quickest breeding response rates for Charadriiformes (terns, gulls, and auks), primarily with social attraction. Given delayed and variable response times to active restoration, 5 y is appropriate before evaluating outcomes. The database and results serve as a model for tracking and evaluating restoration outcomes, and is applicable to measuring conservation interventions for additional threatened taxa.

Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between their foraging areas, breeding colonies, and adjacent nearshore habitats. Its diverse benefits are making island restoration increasingly common and scalable to larger islands and whole archipelagos. We identified the factors that influence breeding seabird abundances throughout the Chagos Archipelago in the Indian Ocean and conducted predictive modeling to estimate the abundances of seabirds that the archipelago could support under invasive predator eradication and native vegetation restoration scenarios. We explored whether the prey base exists to support restored seabird populations across the archipelago, calculated the nitrogen that restored populations of seabirds might produce via their guano, and modeled the cascading conservation gains that island restoration could provide. Restoration was predicted to increase breeding pairs of seabirds to over 280,000, and prey was predicted to be ample to support the revived seabird populations. Restored nutrient fluxes were predicted to result in increases in coral growth rates, reef fish biomasses, and parrotfish grazing and bioerosion rates. Given these potential cross‐ecosystem benefits, our results support island restoration as a conservation priority that could enhance resilience to climatic change effects, such as sea‐level rise and coral bleaching. We encourage the incorporation of our estimates of cross‐ecosystem benefits in prioritization exercises for island restoration.
