The Xerces Society for Invertebrate Conservation is an international nonprofit organization that protects the natural world through the conservation of invertebrates and their habitats. As a science-based organization, we both conduct our own research and rely upon the most up-to-date information to guide our conservation work. Our key program areas are: pollinator conservation, endangered species conservation, and reducing pesticide use and impacts. Scroll on to learn more about our work!
Resolve to Make a Difference in 2020
This year, you can empower people of all ages to take action for the life that sustains us. We are now accepting applications for volunteer Xerces Ambassadors; training will take place in the spring. Thank you for your interest in informing and inspiring new invertebrate advocates!
Help Us Save Western Monarchs
The western monarch population has reached an all-time low—an over 99% decline from historic levels, and an 86% drop from 2017. Join our efforts to stabilize and recover the population—including the Western Monarch Thanksgiving Count!
Conserving the Jewels of the Night
Fireflies are important components of natural ecosystems, and have immense cultural, biological, and economic value. Despite their significance, firefly populations appear to be in decline. Xerces is working to advance scientific knowledge of fireflies and the threats they face, and initiating conservation efforts.
