Dirty Backyard Biology with Damon Tighe

In this immersive three-part episode of 'Crime Pays But Botany Doesn't,' biologist and mycologist Damon Tighe takes listeners on a journey through the hidden worlds of backyard ecology, fungal biology, and regenerative practices. From his early days as an amateur mycologist to his current work with the California Fungal Diversity Survey, Tighe shares innovative, low-tech methods for harnessing nature’s power—such as using nanopore sequencing for community science, 'bathtub PCR' for field-based DNA analysis, and fermenting weeds to supercharge compost heat. He explores the eerie yet brilliant life cycle of the fly-zombie fungus *Entomophthora muscae*, highlighting its potential for natural pest control, while advocating for a 'build it and they will come' philosophy in composting, where soldier fly larvae and worms naturally colonize well-designed systems. Tighe also details practical techniques like inoculating biochar with urine to create odorless, nitrogen-rich soil amendments, cultivating native oyster mushrooms from wood chips using simple tools like an Instapot and solar cooker, and harvesting trichoderma from spent mushroom substrate to protect seedlings. His deep respect for regional biodiversity leads him to emphasize the importance of using native fungi and soil inoculants, especially for challenging species like Texas madrones that depend on obligate mycorrhizal relationships. Throughout, he champions community science through platforms like iNaturalist and DNA sequencing, urging listeners to reconnect with their local ecosystems and challenge ecological apathy. The episode culminates in a reflective conversation on human behavior, where Tighe and the host examine the evolutionary roots of tribalism and its modern manifestations in political polarization. They argue that the current 'winner takes all' culture has eroded the social and philosophical mechanisms that once helped manage conflict, calling instead for a return to mutual respect and dialogue. In a bold yet measured stance, Tighe advocates for the mindful, nature-based use of psychedelics—not as recreational drugs, but as tools for self-insight and ecological connection, challenging the stigma surrounding them, especially in conservative regions like Texas. The episode closes with a powerful call to action: engage directly with the living world, embrace scientific curiosity, and rebuild our relationship with nature through humility, collaboration, and wonder.
