A long winter followed by a cold, wet spring contributed to a significant decrease in Minnesota’s pheasant count, which declined 29 percent from 2012, according to the Minnesota Department of Natural Resources (DNR).
“Minnesota’s results reflect what we’re seeing in other states,” said Rachel Curtis, DNR wildlife research biologist. “South Dakota had a 64 percent decrease in its brood survey. North Dakota’s most-recent rooster crowing count is down 11 percent from last year. And Iowa reported a 19 percent decrease in its August roadside count.”
Minnesota’s 2013 pheasant index is 64 percent below the ten-year average and 72 percent below the long-term average.
Pheasant hunters still are expected to harvest about 246,000 roosters this fall. That’s down 44,000 from last year’s estimate and is less than half the number of pheasants taken during the 2005-2008 seasons when hunting was exceptionally good.
The highest pheasant counts were in the southwest region, where observers reported 51 birds per 100 miles of survey driven. Hunters should find good harvest opportunities in west-central, east-central and south-central Minnesota.
“Pheasant populations respond to habitat abundance and changes in weather,” Curtis said. “The steady downward trend in Minnesota’s pheasant population during the past several years is primarily due to habitat loss. Weather has caused minor fluctuations.”
The most important habitat for pheasants is grassland that remains undisturbed during the nesting season. Protected grasslands account for about 6 percent of the state’s pheasant range. Farmland retirement programs such as Conservation Reserve Program (CRP), Conservation Reserve Enhancement Program, Reinvest in Minnesota and Wetlands Reserve Program make up the largest portion of protected grasslands in the state.
High spring precipitation and below average temperatures hurt nesting this year. This year’s average hatch date was delayed to June 20, which is 11 days later than the 10-year average of June 9.
The pheasant population estimate is part of the DNR’s annual August roadside wildlife survey, which began in 1955. DNR conservation officers and wildlife managers in the farmland region of Minnesota conduct the survey during the first half of August. This year's survey consisted of 171 routes, each 25 miles long, with 152 routes located in the ring-necked pheasant range.
The gray partridge index also decreased from last year and remained below the 10-year average. The cottontail rabbit index increased from last year but stayed below the 10-year and long-term average. The jackrabbit index was 87 percent below the long-term average. Finally, the mourning dove index was 20 percent below last year and lower than the 10-year and long-term averages.
