Border vista

A border vista or boundary vista is any defined cleared space between two areas of foliage intended to provide a clear demarcation line between the two areas. Border vistas are most commonly found along undefended international boundary lines and in landscaping.

The best-known border vista is a six-metre (20 ft) cleared space around unguarded portions of the Canada–United States border.

Similar clearings along the border line are provided for by many international treaties. For example, the 2006 border management treaty between Russia and China provides for a 15-metre wide cleared strip along the two nations' border.
