Pollination: An Essential Ecosystem Service

BEST PRACTICES AND CONSERVATION STRATEGIES FOR
POLLINATORS AND POLLINATION SERVICES
Pollination An Essential Ecosystem Service
2
An estimated one out of every three bites of
food we eat comes from a pollinator.              
In the U.S., pollination by insects produces
40 billion worth of products annually.           
    Worldwide, of the estimated 1,330 crop
plants grown for food, beverages, fibers,spices,
and medicines, approximately 75 are pollinated
by animals.

Habitat Needs of Wild Pollinator
Species Nesting sites undisturbed
areas Protective cover diverse perennial
cover Adequate, clean water few pollutants,
source flow/recharge, water access Access to
territory functional corridors All-season food
access diverse food sources Predator-prey
balance diversity, protection Interdependent
species patches of natural vegetation, avoid
unnecessary disturbance
