Volunteer Information


The Western Monarch Count is a volunteer-powered community science effort to track the status of overwintering western monarchs & their habitat. Join us!

Volunteers for the Western Monarch Count (WMC) have been collecting data since 1997 to improve our understanding of overwintering monarchs in the West. The growing dataset has been utilized to inspire and inform numerous conservation and stewardship measures that support this beloved butterfly and its habitat. As a volunteer for the WMC, you will have the opportunity to contribute to this legacy while surveying one or more western monarch overwintering sites during the Thanksgiving Count and New Year’s Count monitoring periods.

Things to Know Before You Go:


Register before November 1st

New and returning volunteers, please complete the annual WMC volunteer registration form before November 1st, or as instructed by your regional coordinator. Individuals who register after November 1st are not guaranteed training or site coordination for the upcoming monitoring season. If you are unable to receive the required training and site coordination from a regional coordinator, we recommend that you review the educational resources on this website, sign up for volunteer communications and visit a few local sites so that you may join us next year! We appreciate your understanding.

Volunteer Safety

Volunteers are responsible for their own emergency and safety planning while engaging in all WMC volunteer activities. As with any outdoor or field activities, please ensure that you take proper precautions to plan for your safety and wellbeing while volunteering for the WMC. Be sure to bring enough water and food to sustain your activities, prepare for adverse weather conditions, and let a trusted emergency contact know when, where and with who you will be monitoring and when you plan to return.
