Strangely, I've been rather busy over the last week, so I have plunged into the archives for this shot.
I found this miniature forest on the limb of an apple tree a few months ago - this growth of lichen is an indication of low air pollution. This is hardly a surprise as there was not much south of this tree except some forest, a small coastal town, the ocean and antarctica!
You can find more macro shots at Macro Monday 2 and I Heart Macro.
