Um, sorry, this is shop talk for me - the reason I replied on the blog (which didn't take my name for some reason) was so as not to clutter up this lj...

I only realised I had a specialist reading when you commented, and I have to say it's very interesting to have the opinion of someone slightly better versed in this field than I am. Clutter away!

Have you been following the Radio 4 series Planet Earth Under Threat? They've not mentioned the monocultures yet, but it might turn up at some point...
