Monarch Monitoring Blitz 

July 23-August 1, 2021 


Bees, bats, birds and butterflies do us an important service: As they visit flowers to feed on nectar, they carry pollen from plant to plant. This movement of pollen from a flower’s male stamen to its female stigma — or that of the next flower — fertilizes plants and produces fruits and seeds.

Most of the world's flowering plants and crops depend on the hard-working insects and birds we call pollinators. 

Without pollinators, we would miss out on many fruits, vegetables and nuts — not to mention chocolate and coffee.

But pollinators are in trouble.

 

Threats to Pollinators

For the past 25 years, many species of bees and other pollinators have experienced large drops in numbers. Among the causes:

Plight of the Monarch

The monarch butterfly, probably the world’s best-known butterfly, has become the symbol for a whole class of imperiled pollinators.

A monarch butterfly can travel up to 3,000 miles during fall migration. But the spectacular fall flight of millions of monarchs is threatened by loss of habitat in overwintering areas and throughout breeding and migration areas.

In recent decades, numbers of North American monarchs have plummeted. Both the eastern population (which overwinters in Mexico) and the western population (which overwinters in California) are down. Status reports are based on annual counts at overwintering sites.

From 1996 to 2020, the eastern monarch population dropped 88 percent, from an estimated 383 million to just under 45 million.  

Since the 1980s, the western overwintering population has dropped more than 99 percent, from 4.5 million to 1,914 monarchs.

On December 15, 2020, the Fish and Wildlife Service announced a 12-month finding on a petition to list the monarch butterfly under the Endangered Species Act. After a thorough review of the monarch’s status, the Service determined that listing is “warranted, but precluded” at this time because of higher-priority listing actions.

The Service is working with federal and state agencies, tribes and non-government groups to conserve monarchs. These efforts involve engaging the public in creating and restoring habitat for monarchs and other pollinators.

Some 70 pollinator species are so imperiled that they qualify as threatened or endangered under the Endangered Species Act. See the list.

 

How the Fish and Wildlife Service Helps Pollinators

The Fish and Wildlife Service leads many efforts to stabilize and improve pollinator status. For example:

How You Can Help

Here are some simple things you can do to help pollinators.

1) Plant a Pollinator Garden
 
To attract a variety of pollinators, include a selection of plants native to your region. Native milkweed is vital for monarch butterflies to grow, develop and reproduce. Check field guides to find out which plants local caterpillars eat. Find pollinator-friendly plants for your area. Contact your local or state native plant society for help. Your local agricultural extension service is also a good resource.

Other resources for native plants include the Lady Bird Johnson Wildflower Center, with lists of native plant suppliers and a resident horticulturalist to answer questions.

2) Provide Pollinator Nesting Habitat
Pollinators such as bees and hummingbirds need places to nest as well as plants to feed on. Creating these places is surprisingly easy. Overlook some bare patches at the edge of your lawn. Many native bees are ground nesters. They need well-drained bare soil to create burrows.

Other native bees are cavity nesters; they make their homes in dead wood or brush. Leave plant stems, fallen logs or stumps for bees, beetles and flies to use for nesting. Allow some twigs and leaf litter to remain where they fall to provide overwinter shelter for many insect pollinators.

More help on creating pollinator-nesting habitat.  

3) Avoid or Limit Pesticide Use
Make pesticides your option of last resort in battling weeds and crop and garden pests. Try these steps first.
