• Most parameter values are obtainable from the block labeled "Citation:" at the bottom of the targeted IUCN Red List page. The citation shown will provide, from left to right, the |assessor=, |year= and |title= (the binomial species name) parameters.
  • Note that |year= is not necessarily 2015, but is instead the "year published", i.e., the most recent year in which the species has been assessed.
  • The |id= parameter can be obtained from the url of the target page at www.iucnredlist.org, where it is found between a pair of forward slashes ("/"); e.g., use |id=14144 from the url www.iucnredlist.org/details/14144/0.
  • An optional |ref= parameter is supported but seldom used. It allows specification of reference names in Harvard references, for use in the {{citation}} template family (not to be confused with the {{cite}} template family). For example, use of |ref={{harvid}} or |ref={{SfnRef}} templates enables subsequent use of short-format templates like {{sfn}} (see Aardvark and Marsh shrew for examples of usage).

This template is meant to simplify and standardize the Usage notes section of IUCN template documentation pages.

The only required argument is the IUCN version year (without the decimal), which defaults to 2015 to suppress error messages.

For example, {{IUCN Usage notes|2015}} produces the text above this documentation.
