Hi Mike and all,
As with all these kinds of things, expanding #s of geese is not an
unmitigated good thing. If you look up some info on snows and ross's,
you'll see they are actually damaging their own breeding habitat in some
areas of the arctic and subarctic with dramatically increased feeding areas
on sensitive tundra.

Management of these species is difficult, for a complicated set of reasons:
