#15: Tora Rocha and Terry Smith - The Pollinator Posse on Monarchs, their Amazing Lifecycle, and Their Frightening Decline in the West - Part 1

1 hour 6 minutes

Today’s guests are Tora Rocha and Terry Smith, founders of the Oakland, California based Pollinator Posse. The Pollinator Posse creates pollinator-friendly landscaping and fosters appreciation of local ecosystems through outreach, education and direct action. They engage with municipalities, land owners, golf courses, garden groups, and the general public to help people become better stewards of the land.

Terry and Tora make a wonderful team, and have made a huge impact in northern California on a number of fronts. So much so that Tora was recently awarded the Jefferson Award.

Our conversation was wide ranging - and as a result I decided to divide it into two episodes! Today we discuss the origin of the Pollinator Posse and the good fortune that brought Tora and Terry together. We discuss a few of the Posse’s current areas of focus and how they engage the public, including their creative Tees for Bees program that raises awareness about the importance of sustainable landscape practices at golf courses.

Much of today’s episode focuses on the dire situation with the western population of the Monarch butterfly. Western monarchs have distinct behaviors from those seen in the eastern United States, and their population has crashed to frightening lows, well below what is thought to be sustainable. This crash has corresponded with surprising behavioral changes that the Posse is working to better document, along with their conservation partners.

We discuss the Monarch’s life cycle including their mind-blowing metamorphosis, what distinguishes the western population from the eastern population (east of the Rocky Mountains), how populations are even measured in the first place, why they migrate, and the odd behavioral changes suddenly observed in 2020. We also discuss what individuals and land owners can do to help, such as managing the divisive Tropical Milkweed

Next week’s part two continues the discussion of the dramatic decline of insects and what homeowners can do to create better habitat. We discuss the impact of systemic pesticides such as neonicotinoids and how to avoid purchasing plants that are pre-treated with these long lasting pesticides.

We also discuss how healthy habitat gardening is actually less work than maintaining a lawn or traditional garden, and the importance of leaving “messy” areas - which are important for the lifecycle of insects.
