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).
