There is a theory nowadays that woods should be left alone to natural
cycles which may last hundreds of years. At least that a forest is not
a park where everything should be cleaned up and tidy. Dead wood in a
forest is the food for numerous insects. These insects are the basis
of a biodiversity pyramid. Here is some information on it:

For thousands of years the Australian Aborigines have used fire to
manage their lands.
There is a view that current fire dangers in Australia are a result of
the lack of regular fire burning practices.
There is also the view that these burning practices encourage native
vegetation.
And yet another view that these burning practices would discourage
introduced weeds.
There are many who want regular patterned fire burns conducted for the
above reasons.
Having said that, there are at several areas that have not been managed
by humans by fire for many, if not thousands of, years - one where the
Wollemi Pine was found and a few where cycads remain in central and
northern Australia.

My view;
The landuse key is clearly to tag the use of the land by humans.
The natural key is unclear - it seams to be for both things made by
nature and things made by man! To me this confused all and the key
should be discouraged.
It should be replaced by the keys landcover and landform, these have no
implication of human or nature but simply describe the type of feature.
