2007 TWRA EHD Map

[BranchWater]

I didn't want to HiJack the other thread where this was being discussed, so I will post it here. Took me a while to find it but I knew I had it somewhere

.

 

[Stumpbroke]

Very good info there. Thanks for posting facts

 

[Henry3030]

That is the map product TWRA was circulating at the time. Or a version of it. Thanks for digging it out the deep web!!

Apology to LANDMAN: the return interval I stated as 5-7 years for a typical outbreak was inaccurate. My bad. I was over generalizing or relying on my memory. It appears that the interval for NW TN counties is about 10 yrs. According to data sourced from Southeastern Cooperative Wildlife Disease Study of UGA. Again though who cares right? You are always right bwana.


Although the truth doubters, the forgetful, the ignorant and the historical EHD holocaust deniers persist. Surprised on that other thread only about two persons stepped up in that thread to agree with the 2007 date. Folks don't challenge BS enough on here like they should. Widespread passivity and apathy abound for FACTS.

Branchy, I ran a bucubic image processor over what I think the key areas. Your import posting of that is a little grainy. Nonetheless thanks a ton, been grinding my pearlies over "I dont care what Daryl Ratajczak says" in MOUNTAINS of data. "landowners know best"

So since 2008 was not the mass die-off year for EHD, we are left only to conclude that losses witnessed by you could be attributed to aflatoxins in nearby feeders, gamma rays from a distant nebula, alien dissection, or other problems associated with baiting in general.


"The problem is that deer digestion is a finely tuned physiological process. Just the right combination of microorganisms, enzymes, and pH enable deer to digest a normal winter diet of woody vegetation. When offered a sudden supply of corn, a deer's digestive system doesn't have time to adjust to a high carbohydrate diet. The result can be acute acidosis followed by death within 72 hours.

"At the time of death these individuals can appear normal and well fed. It's just that they cannot digest the corn. Within six hours, corn alters the environment in the rumen. It turns the rumen acidic and destroys the microbes needed for normal digestion.

"Not all deer die immediately from acidosis. Its effects vary with the age and health of the individual. Some may simply slow down, get clumsy, and become easy prey to speeding traffic and hungry coyotes.

"It takes deer two to four weeks of feeding on a new food source to establish populations of microbes necessary to digest the new food. It can't happen in just a few days during a snowstorm. And healthy individuals that might survive in the short term often succumb to complications weeks later." -

Henry3030,

I actually disagree with the SCWDS's 10-year interval assessment for TN. I would like to see their data for that. I believe it is normally a 6-7 year outbreak interval for TN.

But much depends on the weather. At 6-7 years, the herd is primed for another major outbreak. Yet that outbreak generally won't happen until the area experiences another major late-summer drought.

 

[Henry3030]

Yeah Brian, I initially said 5-7 in all my ignored posts and exhaustive links posted.

But but but but but

Landman did a subtraction calculation and we know land owner know best.

Additionally, I looked in my notes. I recall approx 20 days where afternoon high temps breached 95f. Further heat-stressing the herd that year. (2007)

Hard, killing freeze burned the oaks on tassle-out
The heat
The drought
And then the EHD timeline was ripe for the perfect storm.

I'm no expert and it has been discussed here several times, but i think corn has a bigger effect on turkey than on deer. some states allow baiting, and if the above statement by Dr. Shalaway was true, then states like KY would have deer dying off constantly and I think the herd is pretty healthy there. Plus I doubt any state DNR would allow baiting if it was bad for deer. In addition, I doubt they would allow people to feed deer in there backyards. Either way if it were bad, it would kill deer.

Studies in the Carolinas--where baiting in the Low Country is legal--found 50% of bait piles tested were contaminated with enough aflatoxin to be dangerous. Yet baiting is still allowed.

 

[Rockhound]

Bsk, what about high ag areas where deer have corn available whether on stalk or what gets left behind in the fields? Do they have a higher immunity to aflatoxin or is it something that actually comes from another process?

:?: May be mistakin but isn't that the year tn had its biggest bucks killed?

That's crazy. I guess it's more about politics than anything else.

How do you think TWRA gets all info one die offs,
hogs, spot lighters, etc

Landowner / hunters reports to GWs
Then GWs pass it on....

But I work with GWs & TWRA on providing
info, many don't....

Aflatoxin producing mold can inhabit standing corn, but it usually does not occur at the incredibly high levels (nor as rapidly) as what occurs in exposed corn left in a pile on the ground. In addition, by the time deer starting using corn fields (late fall), temperatures have dropped to the point mold growth is not as much of a problem. The big problem in the Carolinas is the very early start of seasons (August in some areas), where mold growth on exposed corn is extremely rapid and intense.
