We study the limit of a superprocess controlled by a stochastic flow as $ttoinfty$. It is proved that when $dle 2$, this process suffers long-time local extinction, when $dge 3$, it has a limit which is persistent. The stochastic log-Laplace equation conjectured by Skoulakis and Adler [7] and studied by this author [12] plays a key role in the proofs like the one played by the log-Laplace equation in deriving long-term behavior for usual super-Brownian motion.
