Lincoln county had 612 in 2013. Only 474 in 2014. Looks like a big drop, but it isn't alarming to me. Several of the Saturdays or days that I went to my Lincoln county spot was bad gobbling weather. That means that it made it harder for hard core turkey hunters, and the fair weather guys didn't even attempt at going.
Giles county had 604 in 2014, and 645 in 2013. Not really a big differnece. Looks like it has remained fairly steady (but trending downward) for the past three to four years. I cannot get it to reseearch earlier than 2006. 2006 was big year and then the drop off year was 2007. Went from 890 in 2006 to 738 in 2007. Steady downfall every year after. (Along with what I have been saying along with you others with concerns.)
Only hunted Lawrence one time (because there isn't many there any longer.) Heard one turkey gobble on roost. They had 251 killed in 2014, which is dismal compared to the early to mid 2000s when 450 birds where being checked in. With the huge wildernesses that Lawrence county consist of there is for sure something wrong. It could be weather, disease, predation, etc. Lawrence and Giles are pretty much the same habitat, with Lawrence being better (with less people, towns, and cities.)
