EHD is very common in AL, although most of our native deer have quite an immune response to most native strains of the virus. There’s over a dozen different types. You have to isolate the serotype to distinguish them. Typically years of high mortality are because a serotype they haven’t seen in several years occurs. Blue tongue is not as common in AL. It’s very rare. I can’t think of a single confirmation the years I worked at DCNR.
Matt, I'll admit I still don't know much on this subject. Folks in the area were just saying it was Blue Tongue. Deer sightings were down that year.
