MDC predicts challenging fall turkey hunting season: Brood-survey results show below-average turkey production in 2018

With fall firearms turkey season and archery season underway, the Missouri Department of Conservation predicts it could be a challenging season because this year’s annual wild turkey brood survey shows statewide turkey production was below average. 

The statewide poult-to-hen ratio (PHR) for this year was 0.9, which was 13 percent higher than last year’s ratio but 25 percent lower than the previous five-year average. PHRs ranged from 0.7 in the Ozarks West region, which includes Ozark County, to 1.4 in the Northwest region. Turkey production was higher in norther Missouri this year than in the southern part of the state.

MDC turkey biologist Jason Isabelle said that although this year’s late spring delayed nesting, conditions during the nesting and brood-rearing periods were favorable throughout much of the state. Yet, despite favorable weather, Isabelle said this year’s low production isn’t surprising, considering the trend in PHRs from previous years.

“During the late 1990s, turkey production steadily increased before declining during the 2000s. After once again increasing throughout much of the state from about 2009-2014, we experienced lower production during the last three years,” said Isabelle. “The PHR trend the last several years would have suggested production was going to be low this year.”

Isabelle added that because weather often varies considerably from one year to the next, MDC staff would expect to see much more variability in the PHRs if annual weather variability was the primary driver of turkey production.

“The longer we collect turkey production data, the more it appears that annual variability of weather may not be quite as influential as we once believed,” said Isabelle. “That’s not to say that weather doesn’t affect turkey production. However, the cyclical patterns we’re seeing in PHRs suggest it’s a bit more complicated than that.”

Isabelle acknowledges there is still much to be learned about the factors that affect turkey production—something he and his colleagues are working on.

“We’re looking at our long-term turkey brood survey dataset and trying to tease apart how turkey numbers, weather and landscape and their interactions affect production. This research should help explain some of the trends we’re seeing in turkey production,” Isabelle said.

The good news: Isabelle expects turkey production to bounce back.

“The pattern we’re seeing in PHRs would suggest that turkey production will steadily increase during the coming years,” he said. “This would certainly be welcomed, given the production we’ve experienced the last several years.”

 

How the poult-to-hen ratio is determined

Each summer, as part of the state’s wild turkey brood survey, MDC staff and citizen volunteers record the number of hens and recently hatched turkeys (poults) they see. These observations are then tallied to determine the success of the hatch, which is most often reported as a poult-to-hen ratio, or simply the average number of poults per hen observed during the survey. The PHR is a good measure of nesting success and poult survival, Isabelle said.

“Each year, thousands of citizens participate in the survey, and we are grateful for their contribution,” Isabelle said. “During the three-month survey, participants typically report sightings of 60,000-80,000 turkeys, which is a testament to the large number of dedicated volunteers that take time to participate in the survey each year.”

 

Fall hunting prospects

The below-average production throughout much of the state prompted Isabelle to predict the fall turkey hunting is going to be more challenging this year. “Because we have fewer young birds on the landscape this year, hunters are going to have to put in more time to be successful. This will be especially true in areas where we have good acorn production, which tends to shift turkeys out of open fields and into the timber, and also reduces their movements,” he said.

Isabelle noted that relatively few people hunt turkeys during the fall season, which results in low hunting pressure and little competition among hunters. Unlike the spring season, when about 100,000 turkey hunting permits are purchased in Missouri, typically only about 10,000 hunters purchase fall firearms turkey permits.

“Although the woods tend to get a bit busier toward the end of October with the deer rut approaching, hunting pressure is relatively light during early-to-mid-October, even on public lands,” said Isabelle.

Hunting hours for the fall firearms turkey season, which continues through Oct. 31, are from a half-hour before sunrise to sunset. Fall archery turkey hunting runs  through Nov. 9 and resumes from Nov. 21 to Jan. 15. Shooting hours for the archery season are a half-hour before sunrise to Half-hour after sunset. Both seasons have a limit of two turkeys of either sex.
