Innovative approaches to regeneration on a California ranch
Since 2017 Mark Biaggi has been ranch Manager at TomKat Ranch, and 1800-acre cattle ranch and research center south of San Francisco, California. In this episode he talks about their Mediterranean climate, with six months of winter rain followed by six months of sun, and the necessity of managing first and foremost for water. Through healthy soil practices, including the careful moving and monitoring of livestock, he has helped the ranch increase water retention in the soil––which has led to healthier vegetation, including the return of perennial native grasses. He also talks about the importance of experimentation and a practice called “safe to fail,” which means trying new ideas that could lead to more success but also won’t hurt the business if they don’t work out. And he stresses the importance of reframing the idea of “waste” by repurposing materials once thought of as disposable and putting them to positive use.
