Western Monarch Milkweed Mapper


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!

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.
