Researchers believe the Western Monarch butterfly's population floor is about 30,000. Anything below that number could make it impossible for the species to make a recovery.
And the Thanksgiving Count last fall showed fewer than 30,000 already. Organizations focused on preserving the Monarch put out a call to action to urge people to help the butterflies return to their former numbers.
Those include the Xerces Society, based in Portland.
