Monarch migration shows a big boost in numbers over a year ago
To get to the numbers of monarch butterflies that showed up in the west around Thanksgiving last year, take the previous year's number and multiply by about 123.
It's true; the distressingly low figure of monarchs from a year ago has been wiped off the board. Close to a quarter-million butterflies showed up for the annual migration in California and Arizona, fending off--for now--fears of a collapse of the species.
This does not count as a full recovery, not by a long shot. Portland-based Xerces Society keeps a close eye on the numbers.
