Want to Help Bees? Grow Your Own Food!

Anthony and I have considered carefully how much of the garden we want to allocate to native plants that aren't a direct food source for ourselves vs. traditional orchard and vegetable plants that do feed us. So far we've tried to learn as much as we can about native edibles and have designed the garden to include them.

But it was exciting to learn through the Shutterbee program (read more about that here) that native bees can make great use of traditional vegetable and herb flowers as a pollen source. That's right: As part of my training as a citizen scientist conducting bee studies in my own yard, I was instructed not to overlook the vegetable patch and herb garden.

Most efforts to promote pollinator habitats focus on native flowers such as milkweed and coneflower, which are terrific additions to the garden that we've definitely incorporated. But this is the first I've heard that food plants could support native bees! That's an exciting finding because it means the annual vegetables we're growing get an added "stacked function." In permaculture, that means it has more than one use in the garden - here as both food source for us and a pollen and nectar source for bees. There's even a specialized 'squash bee' that is so-named because it prefers the flowers of squash plants.

For my first official foray into the farmyard to record bees, I was pleased to find that indeed, native bees were busy taking advantage of the flowering vegetable plants. I'd left the arugula standing when it bolted in the summer heat, and it's popular with tiny sweat bees.

So that's one more compelling reason to grow food in your yard. The list was already pretty long, but here's what we've got now. By growing your own food, you will:

  1. Save money, especially if you grow from seeds. You could also get a secondary set of money savings from a reduced need for medicinal interventions, whether that's from traditional medicine or alternatives.
  2. Eat healthier, as your food won't lose integrity via shipping and storing, and if you grow organically, you'll cut out pesticide contamination. You're also likely to eat more veggies because they're fresh and tasty.
  3. Get more in touch with the cycle of life as you take part in it as a mulcher, composter, and seed-sower.
  4. Enjoy a motivating daily workout as you put sweat equity into something that yields more than a toned physique.
  5. And now we can add: Help pollinators by providing them a much better food source than turf grass!

Of course, if you want pollinators to take advantage of the flowers, you need to leave them there. The broccoli I started from seed indoors mostly faltered, but a few took off, and then quickly bolted (next year, we try a different approach). The flowers are pretty, so why not let them go? Ditto the chervil and arugula, both of which love cool weather and are pretty much done now that it's 90+ degrees here in June. That reminds me, the arugula is about to go to seed, so I better get out there and snag the remaining leaves...

Happy yardening! I wish you mulch success!

Beecoming a Citizen Scientist in St. Louis' Shutterbee Program

This spring I joined with 186 other participants in a research project called Shutterbee. Without needing to meet in person, we will conduct a study of the bee populations in our gardens. It basically works like this:

  • Shutterbee ecologists train us in their research techniques and protocol.
  • We learn how to identify, photograph, and record our bee populations using a phone app called iNaturalist.
  • Every two weeks, we spend at least 20 or 30 minutes taking a walking survey of our gardens, photographing bees using the protocol.
  • We then upload our findings to iNaturalist for both Shutterbee's and the general community's ID and record.

I've already gone through the two-stage training sessions, about five hours of education and practice spread over two weekends. Due to COVID-19, the trainings were held online, making this low-touch research project even less-touch. Researchers at Webster University and Saint Louis University are trying to determine whether non-invasive photo surveys can adequately take the place of traditional netting. Normally, bee researchers head out into the field, capturing bees with nets for study. This project explores whether or not photo surveys by citizen scientists can take the place of netting, or at least contribute to it.

This bee on wild garlic is still awaiting ID.

The answer to that seems to lie with us, the program participants. Based on previous years, what researchers have seen is that while the richness and diversity of bee recordings carries across to the citizen scientist findings, we amateurs in the field often miss the rare bee sightings. So Shutterbee has asked us to keep an eye out for bees that seem to break the bee mold, so to speak. For me, being a good citizen scientist means learning as much as I can to think and act like an ecologist, getting to know the bees in my garden and the plants they prefer.

The focus of this study is native bees, not the honeybee, which is a non-native, domesticated insect considered by many to fall into the livestock category. While colony collapse disorder in the European honeybee population is of concern to agriculture, it's the decline in native bee populations that fuels this research project. Native pollinators are important because:

  1. 87% of flowering plants are animal-pollinated
  2. 1 in 3 bites of food we eat is made possible by pollinators
  3. Many of our most nutritious foods need pollinators*

I've already learned a lot from this study, such as how to tell bees from flies or wasps. You might think that's a simple task, but you should think again. Many flies have evolved to mimic the look of bees as a defensive mechanism.

Daisy fleabane
Looks like a bee, but it's a hoverfly called 'margined calligrapher,' here on daisy fleabane growing in our wild patch.

After a few test-walks through the garden, I've also learned that all the work to remove invasive plants and exotics and replace them with native plants is worth it. During my surveys, it was the flowering natives that drew the bees for me to photograph, as shown in all of the photos on this page.

I'm excited to take part in this program, offered jointly by Webster University and Saint Louis University. I served as visiting professor in the game design department at Webster during the 2017-18 school year, and one of my students was our first full-time hire at Brunette Games. Not only is Saint Louis University my undergrad alma mater, but we also recently hired two more students from SLU's English department to our Brunette Games staff.

Professor Nicole Miller-Struttmann has been an awesome educator and evangelist so far in her leadership of Shutterbee, and I look forward to meeting everyone in the program in person, hopefully, in the future. If you're in the St. Louis area and interested in participating, you still can next year. While the program is at capacity for now, it's a multi-year study, and Shutterbee plans to train more people in 2021.
