I see landuse as the primary tag, the values used with it are descriptive.
There are secondary or sub tags such as 'name' that add details.

The landuse=forest will not always have trees on it. From time to time 
they may be harvested and result in no trees.

The density of trees in a forestry area may change over time, Usually 
these areas are, when first planted, fairly dense in the number of 
plants then they are thinned as the trees grow to select the better 
trees to reach maturity.

I don't bother  adding the landcover to landuse=forest as it changes and 
I'm not prepared to track that and map it.

To me the landcover is secondary to the landuse tag in forestry areas as 
one is fairly permanent while the other changes over time.
