Ideally I would like to discover the identity of all the organisms living in my garden. Since I read here however that "There are more organisms in one gram of soil than there are human beings on this Earth!" (does anyone out there have a comment on whether this is fact, speculation or exaggeration?) I guess I am going to have to set some constraints on my search:
I'm going to start with (a somewhat arbitary) Rule 1 therefore: I'll record any organism with a bodily dimension of more than 5mm.
Rule 2 is simpler: if it's alive in my garden I want to know about it. Birds, flowers, mosses, insects, lichens, spiders, trees, mushrooms....they're all 'fair game'
This immediately leads me to speculate over how many organisms I'm eventually going to find.
At this stage I really have no idea!
I am going to take a wild guess and say 250.
I'd be interested to invite comment on this number from readers of this blog. I'll describe some salient features of my garden in the next posting.
