摘要
Worldwide, many wader species have recently exhibited steep declines in range and abundance. Low productivity, frequently associated with predation, is considered a major proximate driver of declines and often reflects underlying land use and habitat change. We hypothesised that restoration of grouse moor management, which includes control of predators and heather habitat management, would halt and reverse these declines. We monitored changes in the abundance of four upland-breeding wader species following restoration of grouse moor management at Langholm Moor in South-west Scotland from 2008 to 2017. Here, Curlew, Golden Plover and Lapwing had previously declined when management ceased, whereas Snipe had increased. During the 10-year study period, Curlew numbers increased on average by 10% per annum, Golden Plover numbers by 16% and Snipe numbers by 21%, whereas Lapwing numbers did not change. These local trends contrast with national and regional trends over the same period, which all showed declines of all these species. However, the population trends for Curlew and Snipe did not differ in relation to habitat management for Red Grouse, suggesting that population increases were primarily associated with predator control across the whole study area. Our results support the hypothesis that restoring predator control as part of grouse moor management can reverse declines of some wader species. At Langholm, full recovery to levels observed prior to management cessation may have been constrained by delayed recruitment within a time-restricted study period in combination with low initial numbers, availability and isolation of suitable habitat, and incomplete predator removal. ZusammenfassungReaktionen von brutenden Watvogeln auf die Wiederaufnahme des Managements fur die Bejagung von Schottischen Moorschneehuhnern auf einem Moor in Sudwest-SchottlandViele Watvogel-Arten sind weltweit durch starke Ruckgange in Ausbreitung und Bestand bedroht. Niedriger Bruterfolg, haufig assoziiert mit Pradation, ist eine der Hauptursachen fur diese Bestandsruckgange, und oft auf Veranderungen in Landnutzung und Habitat zuruckzufuhren. Wir stellen die Hypothese auf, dass die Wiederaufnahme des Managements fur die Bejagung des Schottischen Moorschneehuhns, welches Pradatorenkontrolle und Heidehabitat-Management beinhaltet, diese Bestandsruckgange aufhalten und umkehren kann. Wir beobachteten die Bestandsveranderungen von vier im schottischen Hochland brutenden Watvogel-Arten nach der Wiederaufnahme des Moorschneehuhn-Managements im Langholm Moor (Sudwest-Schottland) zwischen 2008 und 2017. Nach Einstellung des Managements hatten die Bestande vom Gro ss en Brachvogel, Goldregenpfeifer und Kiebitz abgenommen, wohingegen Bekassinen zunahmen. Wahrend unserer 10-jahrigen Studie hat die Anzahl der brutenden Brachvogel durchschnittlich um 10% pro Jahr zugenommen, Goldregenpfeifer um 16% und Bekassinen um 21%, wogegen die Anzahl der Kiebitze gleichblieb. Diese lokalen Bestandszunahmen standen im Gegensatz zu den im gleichen Zeitraum fur alle Arten rucklaufigen nationalen und regionalen Trends. Die Bestandstrends fur Brachvogel und Bekassine waren unabhangig vom Heidehabitat-Management, was darauf hindeutet, dass diese Bestandszunahmen hauptsachlich auf die Pradatorenkontrolle zuruckzufuhren waren. Unsere Ergebnisse bestatigen die Hypothese, dass Pradatorenkontrolle im Rahmen des Moorschneehuhn-Managements die Bestandsruckgange von einigen Watvogel-Arten umkehren kann. Eine vollstandige Erholung der Watvogel-Bestande in Langholm auf das ursprungliche Niveau vor der Einstellung des Managements wurde wahrscheinlich verhindert durch zeitverzogerte Rekrutierung in einer zeit-beschrankten Studie in Kombination mit anfanglich niedrigen Bestanden, eingeschrankter Verfugbarkeit und Fragmentierung von geeignetem Habitat und unvollstandiger Entfernung von Pradatoren.
