| Each year the Iowa Department of
Natural Resources (IDNR) uses a roadside survey to assess its upland game
populations. The August Roadside Survey, as it is called, is
conducted on sunny calm, mornings, with a heavy dew on the grass, between
August 1st-15th of each year. Most upland wildlife, particularly
pheasants, hate to be wet. On mornings with a heavy dew, hen pheasants
bring their broods to the roadsides to dry off before they begin feeding.
This natural tendency allows the birds to be counted and reproduction can
be evaluated by counting the number of broods seen and their size.
Survey routes are 30 miles long and are entirely on gravel roads.
When conditions are favorable, Iowa DNR biologists and conservation officers
drive their assigned routes, at 10-15 mph, and count all the pheasants,
quail, partridge, rabbits, and jackrabbits seen. In all, there are
210-30 mile routes driven (6,300 miles) every August to assess Iowa’s upland
game populations. Most counties have 2 routes, and the information
from all of these routes is condensed to produce Iowa’s
small game distribution map.
