I determined whether ducks might be effective surrogate species for upland and wetland songbirds and shorebirds by comparing effects of habitat management (cattle grazing and field size), distance to other habitats (water, cropland/forage, or roads), local vegetation characteristics, and landscape context (amount and distribution of upland habitat), on the richness, density, and nest success of ducks, songbirds, and shorebirds. Data were collected on density, richness, and nest success of ducks, songbirds and shorebirds in 39 native dry mixed-grass fields in southern Alberta, ranging from 11-3239 ha, that alItem type | Current library | Collection | Call number | Status | Date due | Barcode |
