Geographic contiguity

[1] Other examples of geographical contiguity might include the "contiguous European Union" excluding member states such as Ireland, Sweden, Finland (between Åland and Turku Archipelago), Malta and Cyprus (these being non-contiguous), or the "contiguous United Kingdom" referring to all parts of the country excepting Northern Ireland (it being geographically non-contiguous).

Geographic contiguity is important in biology, especially animal ranges.

For a particular species, its habitat may be a 'contiguous range', or it might be broken, requiring periodic, typically seasonal migrations (see: Disjunct distribution).

The same concept of contiguous range is true for human transportation studies in an attempt to understand census geography.

[3] In United States real property and mineral rights law, touching of two tracts at a common corner (as checkerboarded land) is generally considered contiguous.
