Monarch butterfly populations are thriving in NorthAmerica universityofga
during the summer compensates for butterfly losses due to migration, winter weather and changing environmental factors.populations are in dire trouble, but we found that's not at all the case," said Andy Davis, corresponding author of the study and an assistant research scientist in UGA's Odum School of Ecology."It goes against what everyone thinks, but we found that they're doing quite well.
This study represents the largest and most comprehensive assessment of breeding monarch butterfly population to date. By carefully examining the monarch observations, the team found an overall annual increase in monarch relative abundance of 1.36% per year, suggesting that the breeding population of monarchs in North America is not declining on average. Although wintering populations in Mexico have seen documented declines in past years, the findings suggest that the butterflies' summer breeding in North America makes up for those losses.
"Everybody thinks monarch habitat is being lost left and right, and for some insect species this might be true but not for monarchs," Davis said. If you think about it, monarch habitat is people habitat. Monarchs are really good at utilizing the landscapes we've created for ourselves. Backyard gardens, pastures, roadsides, ditches, old fields—all of that is monarch habitat."
