Bees pollinate about 1/3 of the crops we eat and drink. Without enough bees or other pollinators, there wouldn't be enough food. Not enough almonds or apples. Far fewer blueberries and oranges.
Most of the conversation surrounds honeybees but it is not just those insects which are in trouble. Our native bees and other pollinators, including wasps, hummingbirds, flies, butterflies and moths)
"are also in great trouble due to habitat loss, pesticides and other actions by humans."
A pollination disaster and resulting food shortage will affect all of us - not just gardeners or farmers. Everyone who likes to eat will be impacted by shortage of certain crops and/or sky high prices. So what is a food-eating person supposed to do?
The sign at the entrance to our back garden.
1) Don't Use Pesticides: Pesticides are a trigger for the dramatic demise of pollinators. One class of pesticides - neonicotinoids - have been in the news lately as being particularly deadly to bees, other pollinators, birds and aquatic life.
This class of pesticides is so deadly that the American Bird Conservancy ("ABC") claims it has the potential to impact entire food chains. ABC commissioned a study which found that a single kernel of corn coated with neonicotinoids can kill a songbird and are water sources are already beyond the threshold found to kill many aquatic invertebrates.
Unfortunately, it is not simply neonicotinoids that are killing our pollinators.
"There are hundreds of other chemicals used in conventional agriculture that are also responsible for poisoning bees." Herbicides and fungicides are responsible for negatively impacting bees and other pollinators as well as "regular" pesticides.
The best thing to do is to stop using ALL pesticides, herbicides and fungicides. Research organic alternatives. Get the beer out for the slugs. Employ
white vinegar,
boiling water,
baking soda. And
accept less than perfection in the garden.

2) Buy Organic: In addition to not using pesticides at home,
it is important to support those farmers who eschew pesticides when they grow our food. If you go to the farmers' market, ask if the farm uses pesticides. Many farms do not use pesticides but either cannot afford organic certification or are in the process of becoming "organic."
3) Plant for Pollinators: Habitat destruction is another primary cause of the pollinator demise. What was once fields of wild flowers are now rows of neatly mowed lawns. Dead branches and entire trees used to stand - or fall - where they may. Now, we lop off branches, cut down trees, and grind them in to mulch. Most yards - including mine! - are filled with non-native and sometimes invasive species. I recently read, though, that
"our wildlife gardens are the one of the last lines of defense to protect . . . native pollinators."
Nasturtium, borage and other pollinator friendly flowers in between raised beds increase pollination of your veggies and provide forage for pollinators.
With that in mind, I decided to
roll out the welcome mat to pollinators and other wildlife. Pollinators need
three things: food, a place to live and water.
Plant flowers and flowering plants to provide pollinators with the food they need. Natives are best - though times are desperate for pollinators and habitat is limited. Don't beat yourself up if the seeds you sow or the perennials you stuff into the ground are not native. Also, look for plants that bloom in spring, summer and fall and go for a mix of perennials and annuals so that pollinators can forage almost year round.
Native California poppies reseed themselves throughout our garden - to the delight of pollinators.
Make a home for pollinators. A popular way is to build or buy a
mason bee house. I haven't had much luck with my bee house but
this site has some very promising - and fun - ideas. Create a
brush pile and
leave some ground bare (no mulch, no plastic!) for ground dwelling bees. Last, put up
birdhouses.
My wall of birdhouses. Some have been occupied by birds. Two are currently occupied by bumble bee colonies.
You read that right! I've bought up every birdhouse I come across at garage and estate sales. Mostly because I like the look. Unfortunately, you cannot clean out a bird nest from of some birdhouses. No worries! Bumble bees will thank you for it. I currently have three birdhouses that are host to three different bumble bee colonies. I know I'm not alone. Check out this
an article about a colony of bumbles in another birdhouse.
A birdhouse with an abandoned bird's nest becomes home to a bumble bee colony and my veggie garden and fruit trees get pollination galore!
Even pollinators get thirsty. I have a small container water garden that has hosted many a bee on its lily pads but I'd like to put in a larger water garden later this year.
Another option is to fill a saucer with wine corks or pebbles and water.
My mini container water garden - the easiest garden I ever planted.
4) Speak Up for Our Food Supply: The European Union recently banned neonicotinoids, the deadly pesticide discussed above. In the United States, however, the EPA has decided on a wait and see approach -
even though the USDA says that we do not have enough bees to pollinate America's crops. If you don't think wait and see is going to cut it,
tell the EPA to immediately suspend the use of pesticides suspected to be responsible for large bee die-offs which scientists study the matter further.
While you are at it,
ask Home Depot and Lowes, the nation's two biggest home care retailers, to stop selling neonicotinoids.
Now that you know what to do, go forth and bee happy. Because pollinators
and food are awesome!
