When honey bees are in short supply, native bees can act as an insurance policy when their habitat is present.

Native bees pollinated approximately $3 billion of crops in the year 2000.

Fifty-one species of native bees have been observed visiting watermelon, sunflower, or tomato in California.

Over forty-five species of bees have been recorded pollinating berry crops in Maine and Massachusetts.

Sixty-seven species of native bees visit blueberries in Nova Scotia.

Native pollinators have been shown to nearly triple the production of cherry tomatoes in California.

Wild native bees improve the pollination efficiency of honey bees in hybrid sunflower seed crops by causing them to move between male and female rows more often.

Using native pollinators to pollinate crops and protect habitat

Conservation focused on pollinators is a way to conduct cooperative habitat protection and restoration in working lands.

A win-win for all.

Plants and wildlife

About 70% of the world’s plants require a pollinator

Fruits and seeds are a major part of the diet of about 25% of birds, and many mammals

Pollinators themselves are food for wildlife

Importance of natural areasIf more than 30% of the area within 1.2 km of a field is natural habitat, growers can achieve full pollination of watermelons by native bees in the Central Valley, California

In the absence of honey bees, canola growers make more money on their land if 30% is in natural habitat, rather than planting it all

pollination service• Effectiveness of restoring habitat for native bees

• >50 species visit crops in Yolo County, CA

• Native bees alone provided significant pollination for watermelon farms close to natural habitat

• Native bees shown to increase production of sunflowers and tomatoes

Fully integrating native pollinators into Farm Bill programs can have a wide impact.

The Environmental Quality Incentives Program (EQIP) allocated over $1 billion in financial and technical assistance to farmers in 2006.

Conservation Reserve Program (CRP) retired over 36 million acres of farmland, 4.5 million specifically for wildlife.

Collaboration with NRCSCollaboration with NRCS

Engaging with the NRCS—local level

Engaging with the NRCS—state level

• Help develop regional pollinator technology notes (focus on plant information)

• Training their conservationists

• Engaging in state tech advisory committees to help pollinators stay on the radar

• Help develop pollinator restoration projects


• Working to include pollinators as a priority in NRCS conservation programs

• Current legislation (e.g. Pollinator Habitat Protection Act)
