Zeitliches und räumliches Auftreten rastender Goldregenpfeifer Pluvialis apricaria im Ems Dollart-Raum (Landkreis Leer, westliches Niedersachsen).
The coastal marshes around the River Ems and the Dollard Bay in NW Germany are a core stopover site for migratory and wintering European Golden Plovers. Numbers, spatial distribution, phenology and habitat selection were studied in a 415 km2 agricultural area (30% SPA), mainly constisting of meadows...

Highest numbers of Golden Plovers were usually seen during autumn migration (notably November), with up to 41,000 individuals in autumn 2007.

The coastal marshes around the River Ems and the Dollard Bay in NW Germany are a core stopover site for migratory and wintering European Golden Plovers. Numbers, spatial distribution, phenology and habitat selection were studied in a 415 km2 agricultural area (30% SPA), mainly constisting of meadows and arable fields.
