That is something up to the user...it would sometimes be more efficient 
in memory to use the same level of detail for all trees, for example, 
when you only have a few tree meshes which are copied over the whole 
scene.(a copy of a mesh takes up much less memory than a new one)
In other cases, various methods like textured flat objects or simple 
isosurfaces have been used.

You would probably have to write the program yourself...these things are 
pretty specific. You might be able to find such a program, but I highly 
doubt it would be free(or even cheap).
