Monarch butterflies have been officially listed as Endangered on the IUCN Red List, indicating a high risk of extinction without significant intervention. Their populations are declining primarily due to habitat loss, particularly the eradication of milkweed, which is essential for their life cycle as it serves as both a food source for larvae and a site for egg-laying. The East Bay Area in Silicon Valley is noted for its migratory patterns of monarchs, with local parks providing winter refuge. Planting milkweed is crucial for supporting monarch populations and combating their decline. Conservation efforts are necessary to protect this iconic species and its habitat.
