Somebody did a great job mapping the forests and tracks south of Munich, Germany (the area south of Taufkirchen) using Potlach alpha.
But, unfortunatelly she/he used wrong tags:
key = track
highway = track
So, the forests appear on the map, but not the tracks :-))
I started to *add* this missing tag using JOSM (now visible with Osmarender),
but I must confess: it's a lot of work to do.
When starting to map, please read the HowTo for choosing tags:
otherwise your work could be in vain.
