I think the EHD is an equal opportunity disease and certainly while deer concentration would increase its affect, I'm not sure the farming aspect would be a great factor. If so, we'd probably have heard that in the past. As with my post on the other thread, if it's mud along the waterways that the midges like, this could be a banner year for the EHD in some areas. As suggested though, at least in the wild herds, with the abundance of water, maybe the deer won't be as concentrated lessening some of the impact.
