Pollinators play a crucial role in flowering plant

Pollinators, such as bees, birds, bats and insects, play a crucial role in flowering plant reproduction and in the production of most fruits and vegetables.

Examples of crops that are pollinated include apples, squash, and almonds. Without the assistance of pollinators, most plants cannot produce fruits and seeds. The fruits and seeds of flowering plants are an important food source for people and wildlife. Some of the seeds that are not eaten will eventually produce new plants, helping to maintain the plant population. Over 75% of all flowering plants are pollinated by animals.

Studies say that Honey bees pollinate approximately $15 Billion worth of crops in the U.S. each year. The value of pollination services provided by native bees and other wildlife is even greater. It is estimated that honeybees only pollinate 15% of the most common food crops worldwide.

A recent study of the status of pollinators in North America by the National Academy of Sciences found that populations of honey bees (which are not native to North America) and some wild pollinators are declining. Declines in wild pollinators may be a result of habitat loss and degradation, while declines in managed bees are linked to disease (introduced parasites and pathogens).
