Effects of forest management on density, survival, and population growth of wood thrushes

Article Abstract:

Adult and juvenile songbird survival in the breeding season has not been estimated for forest interior songbirds in management contexts, and little attention has been given to concurrent research into density and demographic parameters. Research undertaken into the impact of winter prescribed burning and forest thinning on breeding wood thrush populations at the Piedmont National Wildlife Refuge in Georgia revealed a silviculture practice model that may merit replication in the whole area. There is a need for long-term monitoring of population responses to management to fully understand and control these systems.

Scrub-successional bird community dynamics in young and mature longleaf pine-wiregrass savannahs

Article Abstract:

Wildlife management practices to preserve a particular species could adversely affect other species. Management for biodiversity and the red-cockaded woodpecker has been studied in South Carolina. Scrub-successional species were more common in stands where longleaf pine had been planted after they had been clearcut, than in stands where mature longleaf pine had been manipulated. Wildlife management schemes should consider early successional bird species, with provision for both late and early-successional habitat on public lands. Habitat offered by surrounding private lands should also be taken into account.

Population dynamics of white-winged scoters

Article Abstract:

Declining numbers of juvenile white-winged scoters in the Atlantic Flyway have raised questions as to the cause. Details of a study examining yearly survival rates and harvesting of the species and their effect on its decline are presented. Annual surveys were examined to discover scoter age ratios. It was discovered that a high harvest rate was not followed by a production rate increase, but that survival rate for the species is reasonably high when compared with other North American water birds.
