[Taxacom] when is a common species critically endangered?

[JF Mate]

Since cultivated Clianthus maximus is maintained by humans the mite is
in effect living in an anthropogenic habitat. Same goes for pests on
many cultivated plants with small or nonexistant wild populations
(Gingko, Avocado, Coffee...). I can´t see the difference between this
an associated faunas of Atta nests.

Feral cats in Europe are replacement predators (native wild cat
populations are much reduced). Domesticated cats are subsidized
hunters, nothing natural about them. Everywhere else they are just
invasives. My two cents.
