Marin Milkweed Monitors

The Marin Milkweed Monitors is a community science initiative to understand the extent and condition of monarch breeding habitat in public lands managed by One Tam partners. Our knowledge of wild native milkweeds in this area is incomplete—Is milkweed present in known historical sites? Are there sites we don’t know about? How are the milkweeds doing? Are monarch butterflies using them to raise their caterpillars? Learn more: https://www.onetam.org/marin-milkweed-monitors

The One Tam partnership mobilizes the resources of the National Park Service, California State Parks, The Marin Municipal Water District, Marin County Parks and Golden Gate National Parks Conservancy to ensure a vibrant future for Mt. Tamalpais. menos ↑
