The Arizona Monarch Collaborative (AMC) is a statewide partnership of agencies, tribes, non-profits, consultants, museums, nurseries, botanical gardens, and universities working to conserve monarch butterflies and native pollinators in Arizona.
We support science-based conservation, information sharing, and on-the-ground action to improve habitat, better understand monarch use of Arizona landscapes, and connect people to meaningful ways to help.

2025 Western Monarch Count Results
2025 Western Monarch Count Results
Each year the Xerces Society for Invertebrate Conservation leads the Western Monarch Count, an annual volunteer-driven, community science initiative that monitors overwintering western monarch butterflies along the Pacific coast. Its primary purpose is to track population health, identify trends, and inform conservation actions to protect the western migratory monarch butterfly population.
Approximately 12,260 monarchs were counted across 249 sites during the most recent count held this winter during November and December 2025. While this is an increase from the 9,119 monarchs counted in the previous year, it remains the 3rd lowest tally since the count began in 1997.
