I think I've found the answer.

Perry: Concurrent legislative jurisdiction is the third type. It is considered partial jurisdiction because
the federal government shares law enforcement responsibilities with the state
and the local officers. In other words,
should a crime occur on area owned concurrently with the state, either a federal
law enforcement agency or a state or local law enforcement agency can respond,
they can investigate, arrest and charge the suspect. If the federal officer or agent handles the
case, that suspect will be tried in federal court. If arrested and charged by a state or local
officer, the case will instead go to state or local court.
Solari: Well it seems like this category, concurrent jurisdiction, gives
the federal law enforcement officer or agent the most options.
Perry: That's true. Many federal
law enforcement agencies prefer to have concurrent jurisdiction on their lands,
because they can share the workload, so to speak, with the state and local
officers. However, concurrent
jurisdiction brings other non-law enforcement responsibilities to that agency
as well, and some agencies prefer to keep their properties held as proprietary
jurisdiction.
Solari: That makes sense. Now Steve,
I've heard the term “Special Maritime & Territorial Jurisdiction”, or
sometimes called SMTJ. I hear that
used. Is that the same as what we're
talking about here?
Perry: Not exactly the same thing.
Exclusive jurisdiction and concurrent jurisdiction are included within
the term Special Maritime & Territorial Jurisdiction, or SMTJ. That is a statute, 18 United States
Code Section 7, that lists areas of federal jurisdiction for which certain
crimes may be prosecuted.
