Again, it depends on what is meant by "nature", also by "separate"
(and perhaps by "human").

But, yes, there is an ecosystem (of sorts) associated with the 
human species, consisting not only of a quite limited number of
livestock species and food plants, but also such things as
dogs (selected for guard duties, the hunt, etc), cats (originally 
selected to keep down mice and rats on farms) and herbs.
But not all species are deliberately selected. What is now
described as "urban flora" (and I presume "urban fauna")
has been selected unintentionally, as are pests (for example
mice, rats, cockroaches, etc). The number of associated
species is still growing, but represents a quite limited subset
of the whole. If things keep moving as they are (that is the
persistent efforts to generate resistant strains of germs and
diseases are unsuccesful, and the human species carries on),
it is an open question of how much of "nature" will remain
outside "the human ecosystem".
