Upland Wildlife & Grasslands

August Roadside Survey Data
August 1-15 annually, DNR biologists and conservation officers drive 215 30-mile survey routes on days when upland game populations are most likely to bring broods to roadsides. This is the most recent survey.

Small Game Harvest Results
Random survey of licensed hunters to determine the size and distribution of Iowa's small game harvest: ring-necked pheasants, bobwhite quail, cottontail rabbit, squirrels, Hungarian partridge and mourning dove.

Mourning Dove Population Status
Data sets from annual surveys are summarized in this federal annual report.

Migratory Bird Hunting Activity and Harvest
The latest estimates from state-reported hunting success from the previous year daily hunting diaries by purchasers of hunting licenses.

Quail Populations and Harvest on Sugema and Kellerton Wildlife Management Areas, 2008-11

Quail populations and harvest were monitored in these wildlife management areas for three years to assess risk of overharvesting.

Genetic diversity and connectivity of white-tailed jackrabbit populations in Iowa with notes on seasonal home ranges, 2010

White-tailed jackrabbits were monitored in 2009-10 to determine how the loss and fragmented habitat (grasslands) has affected movement patterns, space use, population and genetic diversity.

Grassland bird response to enhanced vegetation diversity in restoration plantings in the Spring Run Complex of northwestern Iowa, 2011
Grassland bird habitat use, reproductive success, nestling growth rates, nestling baseline corticosterone, and good glucose levels were compared among restored grasslands planted with seed mixes of varying plant species diversity. Also, a conspecific song playback system was tested to attract Henslow's sparrows to previously unoccupied restored habitat.

CP33 Bird Monitoring and Evaluation Annual Report 2009
Adding upland habitat buffers in row-crop systems increased densities of northern bobwhite, as well as dickcissel and field sparrows. Other succession songbirds exhibited variable response to CP33, possibly due to sensitivity to patch size or habitat structure.

Nest Success of Northern Bobwhite on Managed and Unmanaged Landscapes in Southeast Iowa, 2009
The Lake Sugema Wildlife Area (LSWA) managed for bobwhite was compared to nesting success in Harrisburg Township (HT) in Van Buren County, an agricultural area located 16 km northeast of LSWA in 2003-05.

Sensitivity analyses of a Population Projection Model of Ring-Necked Pheasants, 2007

Data on recruitment and survival was incorporated into a population projection model. By modeling naturally varying weather patterns (based on years 1961-1990), one at a time, in the matrix could help wildlife managers sustain pheasant populations. Early survival of pheasants through reproduction
appears to be managed best by securing nesting cover in clusters of large blocks for diverse vegetation for broods and for providing winter cover.
