Abstract:
Fields where Henslow's sparrows were detected in roadsides surveys in southern Iowa were mapped.
Purpose:
Henslow's sparrows declined from the mid-1960s to the 1990s, but the rate of decline cannot be estimated from the North American Breeding Birds survey. A better survey would probably be concentrated in regions where the species is most abundant. These data indicate where, in Iowa, the species is most frequently encountered.

Overview_Description:
Entity_and_Attribute_Overview:
Mapped entities were surveyed fields. Attibutes of each field included location information: state, county, Township, Range Section. Other attrubutes were treatment (e.g. mowed), type (e.g., CRP, Wildlife Area, Hayfield), whether or not the field was surveyed in 1996 and 1997, whether Henslow's sparrows were detected in each year, and comments (e.g., whether nests were found).
