Many Western monarch butterflies are migrating to California this winter, and biologists are cautiously optimistic that this is just the beginning of their resurgence.
In the 1980s and 1990s, these butterflies would make their way to the shore in flocks, with biologists and volunteers counting over a million each year. Due to the use of pesticides and habitat loss, numbers have been steadily declining – just 30,000 were counted in 2019 and just 2,000 in 2020. Things are going on in 2021, with over 100,000. monarch butterflies have been counted so far this year.
This is encouraging, biologists say, and the number is expected to grow, as counts continue through December 5. Richard Rachman, Thanksgiving coordinator annual Los Angeles County Invertebrate Conservation Society, tell NPR It’s “magical” to see so many monarch butterflies at once, and with his partner, he spotted more than 100 butterflies near the beach in one morning.
It’s too early to tell why there are more monarch butterflies in California this year, and although she warned the butterflies weren’t out of the woods yet, she feels that’s it, says biologist Emma Pelton of the Xerces Society. “Nature gave us a second chance.” More monarch butterflies are “a really good reason to keep in mind that there may still be time to make a difference,” she told NPR, adding that if residents of the western US wanted to help help butterflies, they can grow native plants. succulents and flowers in their yard.
