About Project Monarch Health
Monarch Health is a community science project in which volunteers sample wild monarch butterflies to help track the spread of a protozoan parasite across North America.
Our mission is to understand host -parasite interactions in monarchs and to enhance awareness of monarch biology and conservation through the coupling of community members and scientists.
Monarch Health Newsletter
During summer 2020 and through spring 2021, 166 volunteers from 33 US states and 2 Canadian provinces submitted 6,417 samples to Project Monarch Health. This was down from our peak year of 2018, when > 12,000 samples were submitted. The average number of samples per volunteer in 2020 was 38. Infection prevalence by the protozoan OE was 24.8% across all samples tested, which is slightly higher than in 2019 (20%).
We've highlighted the trends we saw during 2020-21 in our annual newsletter, which can be downloaded from our RESULTS page.
