Описание
Waterbirds were observed during breeding season in the Copper River Delta Area of Alaska. These data include 14 unique taxa observed over a seven-year period. In 1964, an earthquake changed the wetlands of this area, uplifting them by 1.9 meters and draining large areas. Goose breeding populations have since been in decline. These data provide occurrence information at nests.

Описание района исследования | This particular aspect of this study was conducted on a 13-km2 area adjacent to Alaganik Slough on the west side of the Copper River Delta (ca.60 degrees N). Prior to 1964, this area had been brackish sedge (Carex spp.) meadow, maintained by tidal flooding. In 1964, the delta was uplifted 2.0 m by an earthquake that resulted in increased drainage of uplands, near cessation of tidal flooding, and decreased salinity. All ponds and wetlands became fresh water. Shrubs (mainly sweet gale [Myrica gale], alder [Alnus crispa], and willow [Salix spp.]) and trees (cottonwood [Populus balsamifera] and Sitka spruce [Picea sitchensis]) have invaded and now dominate the drier levees. Concurrent with increased woody vegetation, beavers (Castor canadensis) colonized the delta. Large tidal sloughs continued to drain the delta, but tributaries off the main sloughs were dammed by beavers and transformed into long, deep freshwater ponds. Beaver activity also flooded upland, increasing the area of wetland between slough levees and pond basins. These areas continued to be dominated by freshwater sedges and mosses. |
Описание плана выполнения исследований | Birds were captured where possible and marked with neck collars at least 1 year prior to initiation of our study. Capture techniques included bow traps for nesting birds and corral traps for molting and hatch-year birds. We located most nests of collared females during systematic searches of the entire study area. We conducted systematic searches on foot, often using a trained dog, twice each year, and each search took approximately 3 weeks to complete. |

Контроль качества | Aerial surveys of nesting birds are biased because some portion of the population are not observed. For our study, the expansion of aerial surveys was based on nest densities from random ground plots surveyed on foot. This adjustment was calculated as the ratio of the density of nests to the density of indicated pairs observed from aircraft. This calculation was based on active and destroyed nests with the assumption that each nest represented one breeding pair. |
