The annual western number of western monarchs have declined rapidly in recent years, observing the 9,119 peak population in California in California.
The count of XERCES SOCIETY invertebrates is the second lowest since the program was launched in 1997. In 2020, less than 2,000 were observed.
Every year from 2021 to 2024, more than 200,000 people were observed, and sharp drop -offs were endured.

“We are very concerned about the size of the population,” said Emma Pelton, a biologist of Xerces Society’s extinction Species species for the preservation of invertebrates. “We know that small groups are particularly vulnerable to environmental fluctuations. I think that happened this year. The late summer and drought records in the western summer. It is likely that it has contributed to a significant decrease in the third and fourth breeding generations.
The Santa Barbella site owned by Nature Conservance had more than 33,000 monarchs last winter. There were only 198 people this year.
According to the American Fish Wildlife Bureau, the extinction of the west monarch’s butterfly could occur with a 95 % chance by 2080. The service suggests that the monarch’s butterfly is listed to the federal government as an extinction Species species.
“Many people care about the monarchs. The Western monarch coordinator Isis Howard said:” But these actions are not enough. Help the monarch will recover. Therefore, we need to work on a large scale and deal with a wide range of issues such as pesticide pollution and climate change.
