We’ve heard in previous episodes what it’s like to live with invasive zebra and quagga mussels: the costs they can impose, the changes they bring, the clarity they leave in their wake. We learned how they spread, and how managers are working to stay in front of their advances into Big Sky Country. But what if they get here anyway? What are options then? And what does this invasion mean for the landscape? For us? Today in the fourth episode of SubSurface, we’re looking at Plan B, and thinking about what the mussel invasion tells us about ourselves. This is Active Resistance.
