Science Friday Book Club: The Comfort of a Backyard Year, Rewilding with Native Plants

Overview

In the podcast, Science Friday host Flora Lichtman chats with Margaret Renkle about her November book club pick, The Comfort of a Backyard Year. The author blends personal backyard observations with broader questions about biodiversity, climate change, and how our green spaces can support wild neighbors. The conversation also features Douglas Tallamy, who provides a framework for using native plants to foster resilient backyard ecosystems.

Key Insights

• Backyards as ecological laboratories for understanding and mitigating environmental change
• Practical steps to reduce lawn and plant natives that feed local fauna
• Ethical considerations around intervention in wildlife and predation
• Tallamy’s native-plant philosophy as a guide for restoration

Overview

The podcast invites listeners into a conversation about The Comfort of a Backyard Year, a book that uses Margaret Renkle's own yard to explore how humans and wildlife become kin rather than distant observers. The discussion touches on the emotional terrain of reconciling love for nature with the realities of habitat loss, climate change, and the need for active conservation in everyday spaces.

Backyard as a Living Laboratory

Renkle describes a yard that began as a stark, almost sterile landscape dominated by invasive honeysuckle. Through a series of low-cost, nature-friendly changes, she demonstrates how a garden can become a thriving habitat. The mowers’ blade height was raised, leaves were left to over winter, and a native-plant strategy inspired by Douglas Tallamy began to take shape. Native trees like sugar maples, big white oaks, and white pines fostered a food web that supports caterpillars, which in turn feed birds and other wildlife. The process was gradual but deeply rewarding, turning observation into action and wonder into stewardship.

The Tallamy Connection

Douglas Tallamy, described as the godfather of the native-plant movement, is featured in the show. He emphasizes that biodiversity hinges on feeding the food web with plants that native herbivores evolved to eat. His work, including Bringing Nature Home and Oaks, provided Margaret with a clear path for her yard and a broader argument about the role of gardeners in conservation. The conversation emphasizes that restoration is not a failure but an ongoing practice that yields tangible ecological benefits and emotional rewards.

Ethics of Intervention

The podcast delves into the ethics of intervention, balancing a gardener’s desire to help with the recognition that some ecological processes are natural and others are human-influenced. Margaret discusses protecting skinks from feral cats and the broader issue of cats as an invasive species. The dialogue also covers predation as a natural part of ecosystems and how to navigate difficult choices when human actions increase risks for wildlife.

Practical Steps for Listeners

Experts urge listeners to start with small, visible wins. Take stock of lawn area, reduce lawn where possible, plant oaks and leafy understories, and focus on establishing a viable food web. The host also highlights online resources for selecting native plants suitable to local conditions, and redefines the “hell strip” and balcony plantings as valuable wildlife habitat. The show closes with encouragement to view any patch of earth as part of a larger ecological network and to experience the immediate satisfaction of seeing wildlife thrive in response to thoughtful stewardship.

Takeaways

• Small, incremental changes can rapidly transform a yard into habitat.
• Native plants support a complete food web, from caterpillars to birds and beyond.
• Interventions should consider ecological balance and ethical implications.
• Backyard restoration is a practical path to climate resilience and biodiversity.
