What type of wood should I use, and why doesn’t a forest show up in mapnik

In https://www.openstreetmap.org/?lat=46.81373&lon=11.75608&zoom=16&layers=M, what is north should be covered in wood (same as what is in the south, the only thing i changed was adding some nodes on the contour to match it better with the current situation (previously, it was very crude). Now it doesn't show up at all in mapnik, but in osmarenderer it does.

Then there is another thing with wood besides the river, which is wood=mixed, but is it also to be tagged landuse=forest?

One Answer:

That forest area was in two parts(small section near Lienerweg was apart from main part). Fixed it.

Forest areas should be tagged as landuse=forest (if forest is being maintained) or natural=wood (when it is not maintained). On both cases use wood=* to indicate what type of trees grow in that forest.

Another strange (and wrong) thing in that area is usage of layer=* tag. It should not be used on areas like landuse and natural. Take a look at: https://wiki.openstreetmap.org/wiki/Key:layer

Thank you for fixing it (I cannot do it from my current computer).

Regarding the layer thing: The entire landuse=farmland/forest seem to be imported by someone from some official datasets, and they are consistently tagged as layer=-2 (which apparently is used for doing some 'layering' as you would do in a vector drawing application. I started drawing things with no overlap, but with common borders, as I reckon this is the correct way to do it.
