Resources (except Excluded species)
Endangered
(END) – Wisconsin Endangered Species: any species whose continued
existence as a viable component of the state’s wild animals or wild plants is
determined by the Department [Wisconsin DNR] to be in jeopardy on the basis of
scientific evidence (statute 29.604).
Threatened
(THR) – Wisconsin Threatened Species: any species which appears
likely, within the foreseeable future, on the basis of scientific evidence to
become endangered (statute 29.604).
Special
Concern (SC) – Species about which some problem of abundance or
distribution is suspected but not yet proved. The main purpose of this
category is to focus attention on certain species before they become
threatened or endangered.
Extirpated
(X) - Native Wisconsin species now thought to be extinct in Wisconsin.
Ecologically
Invasive - Species able to invade wild areas and outcompete native species,
degrading habitats and causing extensive ecological damage.
Excluded
- Many mistaken reports have appeared in the literature, and for that reason
we have listed a number of species as Excluded to call attention to records
and reports that are doubtful, incorrect, or unvouchered by herbarium
specimens. More often than not, excluded taxa are due to nomenclatural changes
over the years, such as the discovery that a certain name has been misapplied,
or simply errors in identification.
