Did you know it’s travel season for monarch butterflies? Each fall, millions of these black-and-orange butterflies journey south from their summer quarters in the United States to their winter homes, which for some is as far away as Mexico.

In honor of National Pollinator Week, the U.S. Forest Service joins organizations and individuals across the world to celebrate pollinators and share ways to help them survive and thrive.

Pollinators are vital to healthy ecosystems. Eighty percent of flowering plants require pollination by animals to successfully reproduce and produce seeds and fruits. Plants and pollinators together provide the basis for life by converting sunlight into food, materials for shelter, clean air, clean water, medicines, and other necessities of life.

Day and night, pollinators are at work all around us—and it's not just honey bees. Did you know that pollinators are responsible for one out of three bites of food we eat? If you'd like to learn more, we've pulled together five blogs from 2015 highlighting some surprising facts about these busy helpers and the many ways different USDA agencies, farmers, ranchers and other partners are working to keep all pollinators healthy.

The pollinator garden at our library in Princeton, Ill. is a popular rest stop for monarch butterflies on their cross-continental journey. My agency, USDA’s Natural Resources Conservation Service (NRCS), worked with local partners and businesses to create a 2,400-square-foot pollinator garden as a way to educate the public and provide needed pollinator habitat.

We planted the garden designed by our landscape architect Vicki Morrical in 2014. It features 28 plant species and more than 700 plants. Signs help visitors identify the different plants.

No matter where you grew up, you are likely familiar with monarch butterflies. You may have childhood memories from science class when you watched those peculiar green caterpillars transform into beautiful butterflies. Depending on where you live, you may have seen masses of their orange-and-black wings fluttering in the sky while the butterflies were on their annual cross-country migratory journey.

Today, the iconic monarch butterfly is under pressure. Habitat loss has led to a steady decrease in their numbers.

Last month, beautiful monarch butterflies floated across Chicago’s skyline as a part of their annual migration. During this year’s journey, they found more milkweed plants in several places along their paths because of an innovative program that connects urban communities with nature.

Area school kids, their families and teachers involved in an innovative project were thrilled: they had planted milkweeds in schoolyards and home gardens to attract more monarchs to the city … and it worked.  Many of the families are originally from Michoacan, Mexico, where the butterflies spend the winter.

An update to one of USDA’s Natural Resources Conservation Service (NRCS) key conservation programs will enable farmers and ranchers to aid the imperiled monarch butterfly. This year, NRCS updated its Conservation Stewardship Program to include incentives for farmers and ranchers who plant milkweed and other nectar-rich plants favored by monarch butterflies.

Monarch butterflies depend on milkweed to lay their eggs during their annual journey from Mexico to the United States to as far north as Canada. Data show that monarch populations have decreased significantly over the past two decades, in part because of the decrease in native plants, including milkweed, on which their caterpillars feed.

Tomorrow, USDA’s Natural Resources Conservation Service (NRCS) is joining the festivities at the sixth annual Pollinator Festival in honor of National Pollinator Week. Bees, butterflies, bats, birds, beetles and other animals play a critical role in the production of fruit or seeds, including plants that provide our nation’s food, fiber, fuel and medicine.

An estimated $15 billion worth of crops, including more than 90 fruits and vegetables are pollinated by honey bees alone. But despite their value, pollinator populations are dwindling due to threats of habitat loss, disease, parasites and environmental contaminants. That’s why farmers and ranchers are doing their part to improve the health of pollinators while providing benefits to the environment. Producers have worked with NRCS to voluntarily apply conservation practices on hundreds of thousands of acres of land because they know people and pollinators depend on each other for survival.

Cross-posted from the Department of Interior blog:

From birds and bees to butterflies, bats and beetles, pollinators are a diverse group and are critically important to terrestrial life on our planet. Without our help, however, their populations will continue to decline as a result of numerous stressors including loss of habitat, pests and pathogens, and exposure to pesticides.

Bees and other pollinators are essential to America’s agricultural economy and maintain the beauty of our iconic landscapes. Without them, we wouldn’t have most of our vegetables, flowers, fruits or nuts. Honey-bee pollinations alone contribute more than $15 billion in value to U.S. agricultural production each year, but beekeepers reported losing just over 23 percent of honey bee colonies last winter. Other pollinators that help sustain food production and the environment—such as native bees and bats—also are declining.

The buzz of a honey bee and the flutter of a butterfly bring happy thoughts of beautiful gardens. These pollinators are also hard at work providing vital services that are critical to our national and global food supplies. Honey bees to native bees and birds, bats and butterflies help ensure the production of plentiful fruits, nuts, and vegetables. Pollination by honey bees alone adds more than $15 billion in value to agricultural crops each year. Unfortunately, the number of pollinators has been declining in recent years due to many factors.
