The opinion stated by Woyt is that the "demand for life (sic) coral is
devastating the reefs". That may be true or it may not be. Perhaps
someone has actually done some field work to determine the effects of
collecting and its long-term impacts on reefs. By this I mean systematic,
long-term monitoring of collected reefs, "before", "after" and
"after-after" (ie, do the reefs recover in time?). Are some
species/habitats more vulnerable than others to harvesting?
I believe this is being tested in Fiji now, but everything else I've heard
is pretty much anecdotal. Seems to me that it would be a very interesting
problem to tackle -- how quickly will corals recolonize a reef that has
been "devastated" by harvesters? Are the data consistent with storm
damage recovery, or, because corals are havested selectively, is the
end-result something different?
