green drought?

My partner has been talking to an acquaintance who lives near Innisfail.  
She was telling Felicia about the "green drought" in that part of the  
world. She has a hobby plantation of paw-paws and, I think, mangoes, but  
after 8 months of almost continuous rain all her trees have died and her  
planation, and, she reports, other areas round about, have been taken over  
by rampant fungus as the soil is totally waterlogged.
I'm fascinated by this idea. Can anyone comment on this? coming from  
Canberra I've always thought of rain as an unmixed blessing. Does this  
effect work at all in natural vegetation, or is only in modified or  
disturbed habitats?
