As pollinators of native plants, bumble bees play a key role in structuring ecosystems, and they are critical pollinators of agricultural crops. Bumble bees are negatively impacted by habitat loss, agricultural practices, and climate change, with one-quarter of species native to North America now threatened with extinction. California is a bee biodiversity hotspot and the California Bumble Bee Atlas is a community science project to inventory these important pollinators. Please join us for a fun field walk as we learn to catch and identify bumble bees and explore how we can promote their populations.
