Pollinators are essential to a functioning ecosystem. The Xerces Society, an international nonprofit organization that protects wildlife through the conservation of invertebrates and their habitats, reports that the ecological services pollinators provide are necessary for the reproduction of more than 85 percent of the world’s flowering plants, including more than two-thirds of the world’s crop species. 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 voles to bears to humans. In addition, pollinators are also a direct food source for many birds, bats and small mammals.
