[Coral-List] Impact of listing 66 coral species on coral research

The only population estimate that I have found suggests that there are about 14
million A. cervicornis colonies in
the Florida Keys (Miller et al 2008). Given the broad distribution of the
species in the Western Atlantic and what I have seen and read about,  there are perhaps over a hundred million colonies
in existence throughout its range. Although they have declined in many locations, I am still having a hard time wrapping my head around these
numbers and wonder how the general public would react.

Scientist: We are
listing ____ as an endangered species.
Citizen: That’s awful.
How many are left?
Scientist: A hundred million. 

Citizen: Oh.

Is population size a factor in the determination of
threatened / endangered species and how does the population size of A. cervicornis compare to other corals
or other listed species (low? high?) For example in the Florida Keys, A. palmata is much less abundant.
