Let’s explore the world of the Nordic honeybee, or Apis mellifera mellifera, a subspecies that once flourished across Southern Scandinavia, Central, and Western Europe. Today, in Sweden, a mere 1,000 of the 160,000 hives still house these native bees, highlighting a pressing need for conservation efforts. Mats Niklasson brings his unique background in forest history and ecological restoration to the conversation, offering an insightful perspective on the Nordic honeybee, and the importance of biodiversity, conservation, and the intricate balance of our ecosystems.

What are the indirect effects of honey bee introductions on native bee populations and plant pollination patterns? Dr. Maureen Page joins us to share the unique roles that native bees play in our ecosystems, highlighting their differences from their honey-producing cousins and how these distinctions are vital for the health of our planet. The common camas herb, a key focus of the study, will serve as a prime example of how native bees outperform honey bees in pollination effectiveness, thanks to their unique traits and behaviors.
