With the query tool sometimes it is best to click very close the 
boundary of what you want.

Overpass ...

natural=wood should get you most of what you want.

landuse=forest should get you areas that for the most part are tree 
covered most of the time. Some of these are contained in the above 
'natural=wood' things as well.

The particular relation is Relation: 3550886 it is tagged both as 
natural=wood and landcover=trees. Note that some of these relations 
exceed the advised 300 member limit.
I have broken some of them down as I keep on adding 'holes' inside them, 
they get rather large. This may be causing problems such as the above 
query problem.
