re: "So, what is the travel distance of wind-blown pollen?"
When I was stationed in northern Germany, I discovered that I had allergies to pollens that were blowing up from sub-Saharan Africa. This was apparently common enough that the post doctors knew exactly what to test for. That argues for a travel distance measured in thousands of kilometers. Granted, the fraction of long-distance pollen was not large but it was well-within the limits of detection even in the 1980s.
