Grass Pollen?

Further to my posting a few weeks ago where I posted a photo of one of my shoes mildly covered in orange dust from the grass on the reserve, well this morning it had increased considerably, as the photos below illustrate. It had even spread onto my trousers.

If indeed it is grass pollen, then it's no wonder that people get hay fever and a probable reason why even my eyes have been sore this year. Can anybody confirm that it is indeed pollen and not simply some kind of dust. Incidentally, my two white terriers, who are at boot height in the grass, always return home as white as they left, why are they not being stained by the dust?

N.B. I have now found out that it is a rust disease of grassland caused by poor growing conditions and the onset of cooler nights.

As for the reserve in general, well it's pretty dire bird wise at the moment as we endure our usual bone dry September conditions and lovely wet Oare is the centre of attention for local bird life. The only real activity on the Swale NNR at the moment is between the wildfowlers and the Greylag geese and Shellness Point, where a few winter birds such as Wigeon and Brent Geese are straggling in.
