> Wilson at Appalachian State Univ. in NC did his doctoral work surveying
> several NC populations in the 1990s and observed a dramatic decline, both
> during his field work and especially compared to earlier surveys from the
> 1970s. The species may actually be four species, all of which currently
> exist as isolated "population islands". Several populations exist on public
> lands. Both scientific and hobbyist/pet-trade collecting appear to have
> contributed to destabilizing increasingly vulnerable populations (so-called
> stochastic processes, or in this case, decline through random events).
