Researchers say that the population of western monarch butterflies wintering along the California coast has rebounded for a second year in a row.
A monarch butterfly perches on a branch at the Butterfly Farms in Encinitas, Jan. 13, 2022.
“I think we can all celebrate,” said Emma Pelton, a conservation biologist at the Xerces Society, a nonprofit environmental organization that focuses on the conservation of invertebrates. “It’s a sign we have a second chance.”Pelton said it’s not clear why the population has rebounded but one explanation could be that eastern monarch butterflies, which tend to spend the winter in Mexico, could be mixing with their western counterparts.
On the eastern side of the Rocky Mountains, another monarch population travels from southern Canada and the northeastern United States across thousands of miles to spend the winter in central Mexico. Scientists estimate the monarch population in the eastern U.S. has fallen about 80% since the mid-1990s, but the drop-off in the western U.S. has been even steeper.
