   tree-coverage: The coverage of trees in m^2. A lower number means a 
     higher density of trees. A value of 0 indicates no trees.

   tree-range-m: The range at which trees become visible. Note that this
     is not absolute, as trees are loaded in blocks. A lower number means
     trees will not become visible until you are closer.
