Range_(biology)

Population distribution redirects here. For the probability distribution of a statistical population, see Probability distribution and Statistical population.

In biology, the range or distribution of a species is the geographical area within which that species can be found.

The term is often qualified:

• sometimes a distinction is made between a species\' native range and the places to which it has been introduced by human agency (deliberately or accidentally), as well as where it has been re-introduced following extirpation.
• for species which are found in different regions at different times of year, terms such as summer range and winter range are often employed.
• for species where only part of their range is used for breeding activity, the terms breeding range and non-breeding range are used.
• when discussing mobile animals, the species\' natural range is often discussed, as opposed to areas where it occurs as a vagrant.
• geographic or temporal qualifiers are often added e.g. British range or pre-1950 range.
