The appropriate sourcing of seeds for restoration is critical for establishing foundational plant species that support ecosystem functions and services. Genetic analyses of such species can yield insights into patterns of genetic diversity and structuring to inform seed collections. Here we document, for three foundational bulrush species, distinct genetic patterns to guide restoration of wetlands along the iconic Great Salt Lake, the largest lake in western North America. Specifically, Schoenoplectus acutus and Schoenoplectus americanus had moderate levels of site-scale genet richness and relatively low genet richness levels within 1-m 2 plots. These patterns contrast with Bolboschoenus maritimus, which had higher levels of site-and plot-level genet richness, and has therefore likely experienced more recent seedling establishment. At the landscape scale, we found some evidence for genetic isolation of individuals at more remote sites (namely Fish Springs National Wildlife Refuge in the West Desert of Utah), but all species are relatively well dispersed over hundreds of kilometers, a pattern most likely to occur via avian dispersal. In our mechanistic dispersal assessment, we found abundant bulrush seeds present in waterfowl gizzards and those seeds germinated readily despite (or because of) partial digestion. Migratory waterfowl likely facilitate the broad dispersal of all species and may aid in bulrush establishment by breaking seed dormancy. These findings suggest that seeds for restoration should be collected within and among seed source sites to ensure a diverse restoration seed lot that does not disrupt gene flow patterns. Implications for Practice• Wetland managers need to know where to collect seeds within sites and across landscapes for a diverse seed mixture. • Based on our genetic assessments of species widespread in North American wetlands, seed collections within a site should be from plants separated by ≥5 m (Bolboschoenus maritimus) to ≥20 m (Schoenoplectus acutus and Schoenoplectus americanus) to ensure multiple genets are sampled. • Seeds should be collected from multiple sites to maximize genetic diversity, especially for S. acutus and S. americanus, which exhibited lower site-level genet richness. • Sourcing seeds across hundreds of kilometers mimics the broad waterfowl dispersal of these species, and in most instances should not disrupt natural gene flow patterns.

The ʻuaʻu, or Hawaiian Petrel, Pterodroma sandwichensis, is an endangered seabird endemic to the Hawaiian Islands. Although its distribution on some of the islands is well documented, on larger islands such as Hawaiʻi there are significant distribution gaps. Previous work within the Puʻu O ʻUmi Natural Area Reserve (NAR) on Hawaiʻi strongly suggested that a breeding colony of the species was present, but active burrows had not been located making it difficult to focus management actions. Searching for burrows of this nocturnal burrow-nesting seabird had been particularly challenging in the NAR, as the birds are very rare, widely dispersed, and breeding in remote areas with dense vegetation and challenging topography. To locate active burrows, we employed the use of tracking devices to track breeding adults back to their burrows. Six data loggers (e-obs Bird Solar 10g) were attached to transiting birds caught using lights in 2018 and 2019. Overland locational data was then interrogated for concentrated areas of circling and ground activity. This resulted in several areas of concentrated activity and two different locations where tracked birds ended up transmitting from the ground. Burrow searching teams were then deployed to these areas and an active Hawaiian Petrel burrow was located. This represents the first active burrow ever documented in the NAR and the entirety of Kohala Mountain. Management actions have since been initiated to protect birds breeding within the areas defined by our tracking data. Logistical and methodological considerations inherent in the use of telemetry for locating endangered seabird colonies are discussed. Utilisation de la télémétrie pour localiser les terriers du 'uaʻu ou Pétrel des Hawaï (Pterodroma sandwichensis), espèce en voie de disparitionRÉSUMÉ. Le ʻuaʻu, ou Pétrel des Hawaï, Pterodroma sandwichensis, est un oiseau marin en voie de disparition, endémique aux îles Hawaï. Bien que sa répartition sur certaines des îles soit bien connue, ce n'est pas le cas sur les plus grandes îles telles que Hawaii, où des lacunes importantes de connaissance existent. Des travaux antérieurs sur la réserve d'aire naturelle (RAN) Pu'u O 'Umi sur Hawaii ont indiqué qu'il était fort probable qu'une colonie de l'espèce soit présente, mais aucun terrier actif n'a été localisé, rendant difficile la recommandation d'activités de gestion. La recherche de terriers de cet oiseau marin nocturne a été particulièrement difficile dans la RAN, car les oiseaux sont très rares et dispersés, et nichent dans des secteurs éloignés à végétation dense et à topographie difficile. Pour localiser les terriers actifs, nous avons utilisé des dispositifs de suivi destinés à suivre les adultes reproducteurs jusqu'à leur terrier. Six enregistreurs de localisation (e-obs Bird Solar 10 g) ont été fixés sur des oiseaux en transit capturés à l'aide de lampes en 2018 et en 2019. Nous avons ensuite scruté les données de localisation situées à l'intérieur des terres pour trouver des zones de concentration d'activité circulaire et au...
