You cant stop physics so "static" can be interpreted to mean "mainain" over an arbitrary amount of time...although I am not sure why you have focused on to that term.
Leaving aside the troublesome reality of humans being part of the global ecosystem, any forest/wildlife/etc preserve is implicitly maintaining a localized ecosystem over multiple human generations.

AFAIK, the ecological preservation argument is against human changes, to allow the ecosystem to evolve on its own, not to keep it static.
"Leave No Trace" if you will.
