Wild Bees for the Win in Georgia’s Blueberry Crops

 

Penstemon smallii

A couple weeks ago I wrote about my garden’s new Penstemon species. They are still blooming – along with several other species of beardtongue – and the bumblebees are having a blast. Soon my St. John’s wort (Hypericum) shrubs will be in bloom and they’ll move on to it, following seasonal bloom cycles as if their life depended on it.

The bees are not just here to amuse me, they have a role to play. An article published this week by UGA CAES highlighted a study of the role of Georgia’s bees in our blueberry crops. Here are a couple of quotes from the article:

“The study, published in Environmental Entomology, recorded more than 5,000 wild bees, identifying 72 species across 26 genera — the most comprehensive survey of wild bees conducted in Georgia blueberry farms.”

“As part of a broader USDA Natural Resources Conservation Service (NRCS) project aimed at boosting blueberry yields by establishing pollinator- and predator-friendly flowering plants around fields, Sarah Rezende focused on how wild bee populations shift across space and time in southeast Georgia blueberry farms.”

This kind of data gives us an important tool to convince farmers and policy-makers that native plants and the insects that they attract can be significant contributors to their crop success. According to the article, “Georgia ranked third nationally in blueberry production.” The study also emphasizes that having flowering plants across all 3 growing seasons is important to maintain a robust population of those native bees.

“The most important thing farmers and residents can do is support a wide variety of flowering plants that bloom throughout the year. This not only helps sustain a diverse range of bees but also ensures their populations remain strong across seasons. Because different solitary and specialist bee species forage at different times, continuous blooms are essential.”

I've written about native bees before and you might find some of these previous posts helpful. They include resources such as books and lists of plants. And I’ll close with a photo of our spectacular specialist bee, the Southeastern blueberry bee. Georgia's farmers and gardeners can’t afford to lose her.
