Sediment quality in freshwater impoundments at Savannah National Wildlife Refuge.
Freshwater impoundments at Savannah National Wildlife Refuge (NWR), South Carolina, provide an important habitat for wildlife species, but degraded sediment quality in the Savannah River downstream of the discharge from two impoundments have caused concern about potential contaminant problems within the impoundments. The quality of sediments from five impoundments (impoundments no. 1, 2, 6, 7, ...
متن کاملBlack Brant Branta bernicla nigricans grit acquisition at Humboldt Bay, California, USA
The Black Brant Branta bernicla nigricans is a seagrass-obligate goose, strongly tied to the estuaries of the Pacific Flyway coast of North America. Black Brant are unique in that they remain reliant on their traditional food resource, in contrast to other Brent Goose populations that now readily switch to feed on agricultural land during migration and in winter. While Black Brant use of coasta...
متن کاملSimulating Decadal Coastal Morphodynamics
Coastal geomorphic systems provide many services of key importance to humankind, including protection from flood and erosion hazards, diverse habitats and amenity values (Agardy et al., 2005; Jones et al., 2011). However, these systems are widely undergoing degradation that can be substantially attributed to the cumulative direct and indirect effects of human interference. Declining sediment in...
متن کاملForaging home ranges of Black Brant Branta bernicla nigricans during spring stopover at Humboldt Bay, California, USA
Foraging home ranges of Black Brant Branta bernicla nigricans (n = 8) were quantified to determine proportional use of available intertidal habitat during spring migration stopover at Humboldt Bay, California, USA. The average foraging range area was 232 ha (s.d. ± 156 ha) of which 114 ha (s.d. ± 43 ha) was comprised of their primary food, eelgrass Zostera marina; the other habitats included mu...
متن کاملUsing Color Infrared Imagery and Remote Sensing Software to Classify Vegetation at Agassiz National Wildlife Refuge
The ability of remote sensing applications to accurately differentiate priority vegetation types was evaluated on a 664-hectare habitat management unit on Agassiz National Wildlife Refuge, located in Marshall County in northwest Minnesota. The Refuge is a diverse complex of wetland and upland habitats, largely inaccessible by foot. Its relative inaccessibility, coupled with the known occurrence...
