Autumn, and Berlin's Leaves Fall

Dear You, 
here you see my problem. Better: you don't see it - because I couldn't find it.
I was looking for a special photo I took: beautiful yellow leaves on a shining turquoise engine cover - it looks really lovely and I can recall it before my inner eye - but I forgot: when did I take that photo - in 2013? 2012? Couldn't have been in 2011 when we moved to Berlin..?
Yours truly has written a book about order. I love order. I love systems to get the chaos into a sort of order - but though I have entitled my photo-files, these titles are not always totally enlightening - I mean: one title for my 10 days stay in England this year - with over 1000 photos - and what might hide under "miscellaneous/ October 2012"?
So above you get substitutes - not bad, but not what I wanted as an illustration for "Autumn".
Though I should better use the word "Fall". Because the leaves fall.
In the Berliner Zeitung I read that in Berlin each year the trees throw down 70.000 tons of foliage.
Can you imagine that?
Seventy-thousand tons! 
(And they are not counting the leaves of the forests as the Grunewald).
Berlin has about 438.000 trees lining the streets. In summer one often thinks one is walking through an aquarium - a deep shadowy green wavers up to the third floor of the houses, no need for sun protection at the groundfloor - better buy a torch - and with mixed feelings I look from my balcony on the second floor at the oaks in front of our house: they grow, contrary to folks belief, rapidly, and in autumn you hear their funny plop, plop when they throw their acorns on the cars. The car owners don't laugh, but the squirrels and the jays do.
And each of these 438.000 trees has about 50.000 leaves.
The main trees are limetrees/linden trees, followed by plane trees, oaks and chestnuts (in Berlin, the newspaper says, each year they get almost 5.800 tons of acorns and chestnuts for feeding deers etc), maple/acer, robinias/ locust and birchtrees. If you add on the trees from our parks and city-gardens, Berlin has about one million trees.
A very, very green city.
You think I ramble? From the photos to the trees?
Oh no - I follow abundance.
Both - photos and leaves - have cumulated.
One has to get rid of some (the chestnut leaves that are infected by the leafmining moth; the photos which are blah or not pretty).
60.000 tons of the leaves are changed into 40.000 tons of compost (the remaining 10.000 tons of leaves they experiment to change into briquetts form).
Might be a good ratio for my photos?
