Monarch Numbers Up Slightly, But Butterfly Still at Risk of ExtinctionTuesday, January 27th, 2015
The annual overwintering count of monarch butterflies released today shows a modest population rebound from last year’s lowest-ever count of 34 million butterflies, but is still the second lowest population count since surveys began in 1993. The population was expected to be up this winter due to favorable spring and summer weather conditions in the monarch’s U.S. and Canadian breeding areas, as butterfly populations fluctuate widely with changing weather. But the 56.5 million monarchs currently gathered in Mexico for the winter still represents a population decline of 82 percent from the 20-year average — and a decline of 95 percent from the population highs in the mid-1990s.
