“Populations of the charismatic orange and black monarch butterfly have plummeted in recent years. To help with conservation efforts, scientists have calculated the extinction risks for the eastern migratory population of monarchs, which overwinter in Mexico and migrate up through North America during warm spring and summer months. Their new data suggest that these butterflies have a 11–57% chance of going quasi-extinct if new efforts are not taken to protect them. The study was published in Scientific Reports on March 21, 2016. Eastern monarch populations have declined by about 80% over the last decade, primarily because of the destruction of important breeding sites inhabited by milkweed in the U.S. ” To read more click here.
