Description Usage Arguments Value Author(s) Examples
This function check which species (both plants and animals) are considered "invaders" somewhere in the world.
For that end, it checks GISD (http://www.iucngisd.org/gisd) and returns a value, either "Not in GISD" or the brief description presented in GISD.
Note that the webpage contains more information. Also note that the function won't tell you if it's exotic in your area, a lot of exotic species are not considered invaders (yet).
As expected, the function is as good as the database is, which I find quite reliable and well maintained. The database is also able to recognize a lot (but not all) of the species synonyms.
Note that eol
with source of gisd or gisd100 may end up with
different results as this function goes directly to the GISD website, whereas
EOL only updates their GISD data occassionally. See notes in eol
