A Look at the Science of Insect Conservation.

Western monarchs migrate to California annually to overwinter in coastal groves. In her study, Schultz analyzed data reported by the Xerces Society, collected from 1997 to 2016, about monarch populations in the coastal groves, as well as some older data. Schultz found that the average abundance of the western monarch in 2016 was less than 5 percent of the abundance in the 1980s. “What we think we’re seeing is a long-term decline related to threats of habitat loss and pesticides,” she says.
