I have read ALL the info you posted, some years ago. I was hoping to find something a little more up to date and a little more specific. I am glad to see the WNV study.....would love to see some conclusions.
One of the areas that I think about when I ask these questions is the Hawk Mountain area, from Hawk Mt. east through Kempton and clear up Kistler Valley. For as long as I have been roaming around there (35+ years), there was a great population of turkeys throughout that whole area. Great, variable habitat that includes the Blue Mountain, Schochary Ridge, Donat's Peak and all the rolling forest and farm fields in the valleys. About five years ago we started to notice a dip in the population, still plenty of birds, but definitely a dip. The next couple of years the population continued to drop but not so much as to be alarming, just concerning. Then there's these last two years where there's barely more than a few birds....they're gone, or next thing to gone. Half of this area has had no fall season for a long time.
To me, that indicates much more than wet springs when an established population just falls off a cliff like that. Other areas with seemingly the same spring weather still have good populations.
I would love to be able to talk with Mary Jo and give my observations and find out if she's even aware of it.
I don't know what WMUs those areas are in but if you look at the links that have the four years of turkey sighting surveys and compare those units across all of the years you can get a pretty good idea how much the turkey populations have declined. Mary Jo is the one who compiles, studies then uses that data for management direction. So, I assure you she is aware.
If you tell me what units you are concerned about I can provide at least the last five years of the sighting survey results.
I will post those results for the state but they do vary from one unit to another.
Year........Gobblers..........hens...........poults.........unknown......Total turkeys seen......poults/hen
2016.........3402...............7073..........16,740.........3636.................30,851....................2.37
2017.........1940...............4704..........10,720.........3064.................20,428....................2.28
2018.........1120...............2462............5,565..........1261................10,408....................2.26
2019.........1225...............3842............9,975..........1812................16,854....................2.60
2020.........2241...............5,771..........12,252.........2175................22,439....................2.12
I also want to point out a few facts and observations concerning the data. First of all it is the combination of all of the 23 WMUs and not representative of the individual WMU across the state. The next thing everyone needs to understand is that the first three years, 2016-2018, the turkey surveys for only the month of August. The last two years, 2019 and 2020, the surveys were over the two months of July and August, so it isn't a perfect comparison across all five years. In my opinion we have to separate the data into two groups, of the first three years then the last two years to have completely valid comparison results.
But, you can see that the turkey sightings for all sex and age classes declined significantly from 2016 to 2017 then declined even more between 2017 and 2018. Mary Jo and all of the other wildlife management professionals are not only very much aware of those declines but concerned about them and looking for the reasons.
Then in 2019 we saw some increase in the turkey sightings. Even though I am sure Mary Jo has the data separated so she can see just the August counts across each unit I don't have it by the individual months and have just the total for both months. How much of that increase from 2018-2019 is from having two months instead of just one of survey results is hard to tell. But, the positive is that from 2019 to 2020 we saw an increase in turkey sightings across all ages and sex. That indicates that we very likely did see an increase in poult survival in 2019. That is also indicated in the poults/hen data in 2019.
The somewhat concerning part of the 2020 data though is that even though the turkey numbers for each group increased for the year the number of poults/hen was down to the lowest of any of the prior years. That could mean even more turkey decline again this year.
But, again I want to remind everyone that the data is different across the various WMU. If anyone want to see a specific WMU or two I can provide that also n this same format. Or they can simply go to the page of links I provided and look it up across each of the survey years.
