How Hemp Crops Can Help Us Save the Bees
With the conversation surrounding climate change becoming even more urgent than ever, it’s no secret that declining bee populations are wreaking havoc on ecosystems around the globe. In recent years, research has pointed to hemp crops as a potential savior for at least some bee populations. Learn more with myCBD.org!
How Hemp May Help Save Bees
Just two years ago Time magazine reported that more than 700 species of bees in North America are in a continuous decline. While the decline of honeybees in the US and other places of the world has been well-documented in recent years, there are more than 4,000 species of bees who could be looking at the same fate.
Looking at the Decline of Bee Populations
Before we discuss why bees are so important to our ecosystem, it’s important to understand why bee populations have been declining in the first place. It’s speculated that one of the biggest threats to bee populations is the widespread use of pesticides in industrial agriculture.
One study found that almost two-thirds of honeybee hives that were surveyed in the US and Canada contained at least one synthetic pesticide. Scientists are the most worried about a group of insecticides known as neonicotinoids, that are frequently coated on crop seeds such as canola, which many honeybees depend on for pollen. Neonicotinoids have shown to disrupt the instincts of bees, such as navigation and memory.
Another reason bee populations are declining is the varroa mite, which was accidentally introduced to Florida in the mid-1980s from Asia. Most honeybee lines in North America stem from the European honeybee, which has no natural immunity to the varroa mite. Essentially, the varroa mite draws out the bees’ “blood” while at the same time transferring a virus that deforms the bees’ wings.
Poor nutrition, increased suburban development and monocultural farming (the agricultural practice of planting a single crop) are also to blame for the bees’ lack of “better” food choices. Like us, Bees gravitate toward junk food; unfortunately, that means the sugar and corn syrup bees ingest does not contain pollen that increases their resistance to certain diseases.
Why Should I Care About Bees?
Though small, bees are one of, if not the, most important species on our planet. Not only are they responsible for pollinating 70 of the nearly 100 crops that feed the entire global population, but their extinction could also account for the loss of all the plants they pollinate and the animals that eat these plants to survive.
If the bee population continues to dwindle to the point of extinction, we’d have roughly half of the fruits and veggies to choose from when shopping at the grocery store. Some of the most common crops bees are responsible for pollinating include:
- Brussel sprouts
Aside from pollinating many of the foods we eat every day without giving it another thought, there are several species of wild plants that depend on bees to thrive as well. Bees’ pollinating role is also vital in the habitat building of other animals and insects. They’re also responsible for the growth of rainforests, temperate deciduous forests, and savannah woodlands. Bees support the growth of other plants, flowers, and trees and contribute to the complex interconnected ecosystem on which every species on the planet depends on to thrive.
How Can Hemp Help Save Bees?
From restoring depleted soils through phytoremediation, freeing our dependency on fossil fuels, replacing plastic, providing food, reduce the effects of carbon emissions, and preventing deforestation, hemp has a lot of potential to bring some balance back to our highly-unstable world.
So how does this apply to bees?
In 2018, a paper presented at an entomology conference in November by University of Colorado student, Colton O’Brien, reported on 23 different bee species living in Colorado had been caught in traps placed in a hemp field during a one-month period that took place in August.
In his paper, “What’s with all the buzzing?”, O’Brien outlined his experiments at two hemp farms in northern Colorado, where hemp tends to flower between late July and late September. Hemp flowering happens after other species of plants have completed their blooming cycle, which can ultimately lead to a shortage of nutritional pollination sources for bees during these months.
According to the O’Brien’s paper “hemp becomes a valuable pollen source for foraging bees, giving it the potential to have a strong ecological value.”
According to Colorado State University entomologist, Dr. Whitney Cranshaw, it’s “shocking how valuable hemp is as a pollen resource for all kinds of bees.”
Cranshaw told Civilized reporters in 2018 that in areas of the country that don’t have strong populations of flowering plants, hemp production could do wonders to save declining bee populations.
“In this part of the country where there’s not a lot of alternative flowering plants, hemp is a godsend for bees,” Cranshaw says. “I don’t think it’s that big a deal if you’re on the East Coast where there’s lots of other flowers, but you grow it in an arid place like Colorado—particularly in a drought year like this year—I mean the bees are going nuts in the hemp. It’s a wonderful resource.”

With the passing of the 2018 Farm Bill, hemp production throughout the US is expected to expand exponentially. What this means for dwindling bee populations remains yet to be seen, however, the emerging evidence does indeed suggest that hemp can help us save the bees.
