"We know the population sizes, we know the rate of decline, and we know the threats between Mexico where they're threatened by forest loss in just the few acres that they occupy add up to the breeding range where we know the threats can range from use of pesticides, herbicides, habitat loss and climate change."

"Given the threats, it's really unsurprising that populations are declining and declining as fast as they are. And we need to do things now to protect monarchs and keep them from falling further. The listing on the IUCN Red List is a good step in that direction because it draws more attention to the decline of monarchs and the need to promote their recovery."

STORYLINE:
Migrating monarch butterflies have fluttered closer to extinction in the past decade – prompting scientists to officially designate them as "endangered," the International Union for the Conservation of Nature announced on Thursday.
The IUCN estimates that the iconic orange and black butterflies have declined between 22% and 72% over ten years.
"Given the threats, it's really unsurprising that populations are declining and declining as fast as they are. And we need to do things now to protect monarchs and keep them from falling further," said Nick Haddad, a conservation biologist at Michigan State University.
In North America, the butterflies undertake the longest migration of any insect species known to science. After spending winters in central Mexico, the first generation migrates north toward Texas. While the butterflies only live a few months, their offspring and grand-offspring continue the journey for thousands of miles, reaching southern Canada, before turning back to repeat the cycle.
A smaller population in North America spends winters in coastal California, then disperses in spring and summer across several states west of the Rocky Mountains. This population has seen an even more precipitous decline than the eastern monarchs.
"The listing on the IUCN Red List is a good step in that direction because it draws more attention to the decline of monarchs and the need to promote their recovery," Haddad said.
Nonmigratory monarch butterflies in Central and South America were not designated as endangered.
