Bees are undoubtedly the most abundant pollinators of flowering plants in our environment. The service that bees and other pollinators provide allows nearly 70% of all flowering plants to reproduce; the fruits and seeds from insect pollinated plants account for over 30% of the foods and beverages that humans consume.
Beyond agriculture, pollinators are keystone species in most terrestrial ecosystems. Fruits and seeds derived from insect pollination are a major part of the diet of approximately 25 percent of all birds, and of mammals ranging from red-backed voles to grizzly bears. However, many of our native bee pollinators are at risk, and the status of many more is unknown. Habitat loss, alteration, and fragmentation, pesticide use, and introduced diseases all contribute to declines of bees.
The Xerces Society is working to research and conserve these vital pollinators. Scroll down or use the search tools to view our profiles of at-risk bees.
