Monarch Conservation & the Power of Community Science

Want to help the monarch butterfly? Join us and the Xerces Society for an inspiring science talk on the western monarch population. Learn about these butterflies' incredible migration to our California coastline, their fragile ecology, and the simple steps we can all take to help them recover. While actions are urgent, the opportunities for impact are great. You'll leave with fun facts, local community connections, and a clear vision of your role in the monarch's comeback story.

Based in Sonoma County, California, Isis works to protect western monarch butterflies across their breeding, migratory, and overwintering ranges. She provides technical assistance and training to land managers and the public on habitat restoration, monitoring and data collection, and pollinator conservation. She also manages community science programs, including the Western Monarch Count and Western Monarch Milkweed Mapper, and coordinates the International Monarch Monitoring Blitz with several national partners. Isis is an experienced outdoor educator and holds a bachelor of science degree in environmental management and protection from Cal Poly, San Luis Obispo

Policy and Advocacy for Birds and their Habitats

November 3, 2026 Election

Madrone Audubon Society SUPPORTS:

Measure H

A YES vote on Measure H supports renewing a sales tax of 0.125% with revenue dedicated to the protection of parks, water supplies, and fish and wildlife habitat; reduction of wildfire risk; and expansion of walking, hiking, and biking trails. 2/3 needed to pass.

Measure H reads: Without raising taxes, to improve and protect Sonoma County’s regional and neighborhood parks; safeguard water supplies, streams, rivers; reduce future wildfire risk; preserve fish and wildlife habitat; conserve natural areas for future generations; expand walking, hiking, and biking trails.

Measure H would mean that Sonoma County continues a one-eighth-cent special transaction and use tax (sales tax) countywide until ended by voters, providing approximately $15.5 million annually, with community oversight, public disclosure, and annual audits.

Madrone Audubon Society OPPOSES:

Prop 45

Prop 45 would amend the California Environmental Quality Act (CEQA). A NO vote on this measure means: Public and private projects would continue to use existing project review and court challenge procedures under CEQA.

Prop 45 would limit the environmental and public review of projects currently required under CEQA and make it more difficult to enforce CEQA’s protections. Since created in 1970, CEQA has required that development and infrastructure projects reduce or mitigate impacts to communities and the environment, and that the public and decision makers are notified in a timely manner in advance of project approval.

Prop 45 would undermine CEQA’s protection by imposing unreasonable time constraints on public input, even for very large-scale infrastructure projects, eliminate key environmental analyses and reduces legal avenues available to members of the community to ensure developers comply with CEQA.

Madrone Audubon’s 59th Annual West Sonoma County Christmas Bird Count (CBC) will be on Sunday, December 27, 2026.

Observers of all experience levels are welcome! Details on how to participate will be posted in November.

National Audubon's Christmas Bird Count is the longest running Citizen Science survey in the world. Started by Frank Chapman in Boston and New York in December, 1900, it provides critical data on population trends across North America, Hawaii, and now areas in Central and South America as well. By participating in a CBC you make an important contribution to conservation. Audubon and other organizations use the data collected to assess the health of bird populations, which helps to guide conservation action.
