transfrontier
Across national lines
Transfrontier means crossing or spanning national borders.
The term appears in formal contexts—policy documents, conservation agreements, environmental law: transfrontier pollution, transfrontier parks.
A transfrontier park, for instance, links protected areas across adjacent countries, allowing wildlife to roam without regard to political boundaries.
