Pollinator diversity, especially in urban environments, has rapidly declined in recent years. Pollinators — including bees, wasps, butterflies and ants — are crucial components of functioning ecosystems. They are prime examples of ecosystem service providers, benefiting people by pollinating food crops globally and supporting California’s $21 billion agricultural industry. Understanding what variables affect pollinator distribution, abundance and visitation is critical to the health and well-being of everyone on this planet. In collaboration with the Theodore Payne Foundation, our team will assess whether California native plants affect pollinator abundance and diversity.
