Insects Lose as Trump Administration Weakens the Endangered Species Act
Published on August 29, 2019
Who really wants to live in and pass on a world without a diversity of butterflies to fill the sky, bees to pollinate our food and flowers, and fireflies to light up the night? Clearly, those who wrote and support these new rules think that is an acceptable future.
Community Science Powers New Western Monarch Studies

Working to Conserve Monarchs from Coast to Coast
Published on June 21, 2019
The migration of monarch butterflies (Danaus plexippus plexippus) is an awe-inspiring sight that heralds the changing seasons across much of North America. Sadly, these inspiring migrations have experienced significant declines in the past few decades. The Xerces Society is working across the U.S. to conserve this beloved species, and there are a number of ways you can help!
New iNaturalist Project Makes it Easier to Submit Data to the Western Monarch Milkweed Mapper
Published on June 7, 2019
Now you can submit data to the Western Monarch Milkweed Mapper using the iNaturalist app on a smartphone or tablet (iOS and Android are both supported). This new way of submitting data makes it easier to share photos and locality data—and we need all hands on deck this season, to better understand the hurdles facing the imperiled western monarch population!
How to Support Monarch Butterfly Conservation—During Earth Week and Beyond!
Published on April 27, 2019
Helping the monarch back to full health isn’t going to be easy or quick, but we can’t stand by and do nothing. If we all plant a small patch of milkweed and nectar plants, and all think about how we can change our actions to make things better for monarchs, together we can transform the landscape to allow the monarch to rebound—and give our children the gift of watching orange wings flap in the sunshine.
Community Scientists Can Help Support Imperiled Western Monarchs
Published on March 12, 2019
We encourage everyone to take some time while hiking in the California coast range, California Central Valley, and the rest of the West, to help researchers by submitting any and all monarch and milkweed observations this year to the Western Monarch Milkweed Mapper website.

Early Thanksgiving Counts Show a Critically Low Monarch Population in California
Published on November 29, 2018
The California overwintering population has been reduced to less than 0.5% of its historical size, and has declined by 86% compared to 2017. While western monarchs are facing unprecedented challenges right now, there is still hope that we can recover the population if we work quickly, strategically, and together.
Western Monarch Numbers Expected to Be Low this Year
Published on November 15, 2018
You may be asking “What can I do to help the monarch?” Besides protecting habitat, avoiding pesticide use, and planting gardens, another way is to contribute monarch and milkweed data to Xerces-led citizen science efforts—namely, the Western Monarch Thanksgiving Count and the Western Monarch Milkweed Mapper.
Keep Monarchs Wild!
Published on September 11, 2018
Instead of rearing—which is risky and unproven in helping monarchs—we should focus on more effective ways to conserve these glorious wild animals. Our tactics should address the reasons the species is in trouble to begin with. We can do this through taking action to protect natural habitat; to plant native milkweed and flowers; avoid pesticides; support wildlife-friendly, local, and organic agriculture; contribute to research efforts via citizen science; and organize ourselves to push for policy changes.
