A tragic bee-ginning to 2017

Tuesday the 10th of January was a notable day in American history. But not for a reason worth cheering about.

The rusty patched bumble bee (Bombis affinis) was placed on the Endangered Species List by the U.S. Fish and Wildlife Service, a first for the continental U.S. Other native bees may soon follow.

According to Tamara Smith, a biologist with the service, the bee was once so prevalent in Midwest cities, people used to shoo them away. 20 years later, even sharp-eyed scientists are having difficulty spotting one.


In fact, since the late 1990’s the rusty-patched bumble bee population has declined by 90 %. Once found in 28 states, the bee is now reported in only 13 states and 1 Canadian province: Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Minnesota, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, Wisconsin – and Ontario, Canada.


There is no one culprit when comes to the demise of bees:  habitat loss, climate change, exposure to pesticides, and disease all contribute.

For example, not long ago the grasslands and tallgrass prairies of the Upper Midwest and Northeast  were alive with bees. Sadly most of these habitats are now gone for a variety of reasons.

As for pesticides, the U.S. Fish and Wildlife Service says bees can absorb toxins directly through their exoskeleton and through contaminated nectar and pollen. Rusty patched bumble bees nest in the ground and may be susceptible to pesticides that persist in agricultural soils, lawns and turf.


 After the endangered bee was announced, the White House launched its strategy to improve the health of honeybees and other pollinators. This plan aims to reduce losses for commercial honeybees over the next decade. The White House will also ask federal agencies to help restore 7 million acres of pollinator-friendly habitat, so as to improve bee diets and make them more resilient.

This is something we should all applaud no matter which side of the aisle you prefer. Why? The USFWS sums it succinctly:



“As pollinators, rusty patched bumble bees contribute to our food security and the healthy functioning of our ecosystems. Bumble bees are keystone species in most ecosystems, necessary not only for native wildflower reproduction, but also for creating seeds and fruits that feed wildlife as diverse as songbirds and grizzly bears.

 Bumble bees are among the most important pollinators of crops such as blueberries, cranberries, and clover and almost the only insect pollinators of tomatoes. Bumble bees are more effective pollinators than honey bees for some crops because of their ability to “buzz pollinate.” The economic value of pollination services provided by native insects (mostly bees) is estimated at $3 billion per year in the United States.”

How you can lend a hand

Various species of bees, along with moths, butterflies, birds, bats and other animals are pollinators. The pollen (powderlike material from the male parts of flowers) they move between flowers of the same species results in fertilization, enabling plants to produce blooms, seeds or fruits. 

 
No room for a garden? Add flowering pots or a window box
Gardeners can play an important role in helping pollinators like bees increase their numbers by offering essential food, water and shelter. Even those who don’t have a garden can participate by planting window boxes and containers with bee favorites.

The first step is to choose plants for your garden that supply a diversity of nectar and pollen throughout the growing season.  Bees are partial to plants living in their own habitats, so choose wildflowers and natives whenever possible. Not sure which natives flourish near you? Visit the Pollinator Partnership and type in your zip code on the Planting Guide page, and you’ll be able to download a PDF with specific recommendations for your area. 

Bees love coneflowers

There is also a helpful Bloom Period guide so you can have something flowering from spring to fall.  Native plant societies can offer additional guidance.

Beyond natives
If natives aren’t readily available, you can find bee-approved choices at most local nurseries and garden centers. (Before buying, ask if their plants have been bred with neonicinoids, pesticides that can harm or kill bees.) Pesticide-free verbena, rudbeckia, yarrow, salvias, coneflowers and flowering herbs are all good choices. Catmints are particularly useful because they will continue to bloom deep into fall with regular trimming.


Heirlooms from grandmother’s garden such as daisies, hollyhocks, asters, and old-fashioned roses are especially attractive to bees. (Flat flowers like daisies and single roses make it easier for bees to collect pollen.) Even veggies can be part of the plan: pollinators will make a beeline for cucumber and squash flowers.

Colors and clusters
Yellow is mellow to bees
Entomologists studying bees have learned they can see four colors – yellow, blue, bluish green (which is how they view white) and violet. They perceive red as black. So when considering plant varieties, your palette should include the blue, yellow and purple flowers bees find appealing.

Choose a sunny location and set out your plants in groups. Again, be sure to stagger bloom times so there will be food available throughout the year. And avoid using pesticides that can be toxic to bees.

Water and shelter
Twigs keep bees from drowning
Although we rarely see them taking a drink, bees appreciate gardens that offer a source of water. It can be as simple as filling a shallow dish with small stones and twigs so bees can land and rest while drinking. A birdbath also offers a dependable destination for bees to take a sip when necessary. Be sure to use clean, chemical free water, and replace supplies regularly.

According to the USDA Natural Resources Conservation Service, there are over 5,000 different species of native or wild bees living in the US. These bees don’t live in hives like honeybees but in logs, dead tree limbs, even in holes in the ground. 

 
Home for solitary bees
As part of the garden, leave an area of bare dirt for ground nesters. You can even build your own shelter by drilling holes in an untreated wood block. The holes should be 3” to 5” deep and approximately ¼” in diameter. Allow an inch between each hole. Choose a site for your “nest” that is protected as much as possible from wind and rain, under the eaves of a shed, for example.

These habitats, along with access to water and bee friendly plants, will create an environment that will soon have your local pollinators buzzing.

And will help solve a bee-deviling problem

Excellent post! The bees thank you. ;-)

And I thank you so much for taking a look!

What excellent information! We sure don't want to try to garden without our pollinators! 🐝🦋🐝 Thanks Lynn!

Teresa, Einstein gives us four years after bees are gone. I will be working hard to make more people aware of what is happening with this worrying issue.

Hello Lynn, we hear so much about bee decline and how serious a problem it is one wonders just how bad it needs to get before there is a coherent and concerted effort driven from the top to help reverse it. For my own garden, it feels like a race to plant, cultivate and establish and ecosystem from soil to top predators. I simply can't garden fast enough and can't cram enough flowers in to do my bit.

Lynn Hunt said...

Sunil, I feel as though there is a more concerted effort to do something in the UK than here. In fact, the new administration appears to being going backwards when it comes to the environment. Your beautiful garden is a pollinator paradise. I tell folks who don't have a garden that even a hanging basket with the proper flowers can help. Believe me, you are doing way more than your "bit".

I hope warnings like this will help turn the tide, but I honestly feel as if it may be too late for many creatures. I welcome being proven wrong.

Lynn Hunt said...

Les, I fear you are right. If the rusty patched bumble bee cannot get on the list, the other three that were supposed to be named don't have a chance. I am trying to do my part to bring these facts to light, but people just don't seem to care as much as they should.

Thank you so much for your kind words, Mary. Hope you will stop by again!
