A new national mosaic of state landcover data A new national mosaic of state landcover data
This presentation reviewed current landcover mapping efforts and presented a new preliminary, national mosaic of Gap Analysis Program (GAP) and Multi-Resolution Land Characteristics Consortium (MRLC) landcover data with a discussion of techniques, problems faced, and future refinements.

Combining information from monitoring programs: Complications associated with indices and geographic scale Combining information from monitoring programs: Complications associated with indices and geographic scale
To adequately monitor Neotropical migratory birds, information must be collected to assess population change at local, regional, and continent-wide scales. I suggest that large-scale survey results (such as those derived from the North American Breeding Bird Survey) should not be used to predict population attributes on parks, refuges, and other protected areas. These areas are often...

Comparison of helicopter and ground surveys of waterfowl broods in southern Ontario Comparison of helicopter and ground surveys of waterfowl broods in southern Ontario
Managers often employ aerial survey information to manage waterfowl. Results of surveys by helicopter and from elevated platforms were compared to determine the accuracy of helicopters to detect waterfowl broods on beaver ponds in southern Ontario in 1996 and 1997. Fewer broods were detected from the helicopter than by observers in elevated platforms at wetland margins. When broods were

GIS interpolations of witness tree records (1839-1866) for northern Wisconsin at multiple scales GIS interpolations of witness tree records (1839-1866) for northern Wisconsin at multiple scales
To construct forest landscape of pre-European settlement periods, we developed a GIS interpolation approach to convert witness tree records of the U.S. General Land Office (GLO) survey from point to polygon data, which better described continuously distributed vegetation. The witness tree records (1839-1866) were processed for a 3-million ha landscape in northern Wisconsin, U.S.A. at...

The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report
The Cape Sable Seaside Sparrow (Ammodramus maritimus mirabilis) was listed as an original member of the federal list of endangered species in 1968. It is restricted to seasonally flooded prairies of extreme southern Florida and is disjunct from all other conspecific breeding populations (Kushlan et al 1982, McDonald 1988). Since the subspecies was described in 1919, its populations have...

Estuaries of the northeastern United States: Habitat and land use signatures Estuaries of the northeastern United States: Habitat and land use signatures
Geographic signatures are physical, chemical, biotic, and human-induced characteristics or processes that help define similar or unique features of estuaries along latitudinal or geographic gradients. Geomorphologically, estuaries of the northeastern U.S., from the Hudson River estuary and northward along the Gulf of Maine shoreline, are highly diverse because of a complex bedrock...
