"Monarch production will not be replicated next year, experts warn, as above average temperatures will cause problems"

"The population of monarch butterflies wintering in central Mexico is up 144% over last year, according to new research.

The data was cheered but scientists quickly warned that it does not mean the butterflies that migrate from Canada and the United States are out of danger.

This winter, researchers found the butterflies occupying 14.95 acres (6.05 hectares) of pine and fir forests in the mountains of Michoacan and Mexico states – an increase from 6.12 acres a year ago."
