This developed from a simple question of how to map a tree area that has 
holes in it of scrub etc.
A fairly simply question?

The simple answer is to map the tree area as a relation with;
natural=wood (even if not 'natural' as OSM acepts that the key 'natural' 
encompass things that many regard as not 'natural'), type multipolygon,
The surrounding closed way with the role outer.
Then place simple closed way/s for the hole/s tagged natural=scrub as 
appropriate .. and then place them in the relation with the role 'inner'.

The problem came the simple use of the word forest!

There is no need to wait for other steps to use the tag 
landuse=forestry, it does not conflict with 'landcover' or 'natural' 
Many keys and values are developed in parallel.
