Mountain lions are slipping through our neighborhoods under the cover of darkness, radically altering their behavior just to avoid us. In this episode, Chris Wilmers, UC Santa Cruz professor of wildlife ecology, pulls back the curtain on the cryptic world of our region's apex predators. From a toothless "old man" puma targeting local livestock to the hidden ways backyard rat poison disrupts local food webs, Wilmers breaks down the true cost of human coexistence. As concrete barriers slice ancient habitats into fragments, local conservationists are fighting back with innovative wildlife crossings. Can these modern solutions truly mend a fractured landscape, or will a dominant male's desperate attempt to cross Highway 17 end in disaster?

How does science actually become law? In this episode current Santa Cruz Mayor, Fred Keeley, reflects on his legendary career rewriting California’s ocean protection rules. From body surfing through literal oil slicks as a nine-year-old to passing the historic Marine Life Management Act at the final midnight hour of a governor's term, Keeley shares what it really takes to build a "Blue Wall" for the coast. But with old political battles over offshore drilling and seabed mining rearing their heads once again right here in the Monterey Bay, the stakes have never been higher. As one of our region’s most iconic policymakers prepares for retirement, he passes the baton to a new wave of local coastal leaders who must now defend these waters.

The California coast is witnessing a silent crash in peregrine falcons that threatens to outpace the devastating legacy of DDT. In this guest-hosted episode, Zeka Glucs, Director of the UC Santa Cruz Predatory Bird Research Group leads us into the field to track the invisible killer: bird flu. From the studio to the windswept bluffs of Devil's Slide, we witness the frontlines of an ecological battle against a virus these apex predators simply can't outfly. As Zeka's team monitors this unfolding crisis, we’re forced to confront the fragility of a recovery we once thought was permanent. We’re left to wonder: can these icons survive a second near-extinction, or are we witnessing the final flight of the peregrine on the Santa Cruz coast?

The morning of April 2nd gave Santa Cruz a sharp reminder that the ground beneath our feet is never truly still. In this episode, we use that recent shake to uncover the seismic secrets lurking under our feet with Emily Brodsky, an earthquake scientist and UC Santa Cruz professor. From the legacy of the 1906 disaster to modern earthquakes triggered by geothermal energy and fracking, we explore the chain reactions that link tremors across the globe. As human activity shifts the stress on these deep-seated faults, we investigate if we are unknowingly triggering a cycle we can't stop. Is it possible to predict the next big shake, or will the next shift in the California coast, like the one on April 2nd, catch us all by surprise?

Santa Cruz is squeezed between the mountains and the sea, there is simply no more land to expand roads for more cars. Matt Miller, Director of Mobility Transformation at Ecology Action, is navigating this bottleneck through the Complete Streets Initiative: a plan to prioritize people over pavement. From the total makeover of Bay Street to new designs in Capitola, this conversation examines a future where streets function less like speedways and more like shared community spaces. But as the city begins to prioritize safety over speed, will these changes be enough to redefine the local relationship with the road, or will the friction of change prove too much for Santa Cruz to handle?

Santa Cruz city planners are moving fast, but the Pacific Ocean is moving faster. This week, Tiffany Wise-West, the Sustainability and Resiliency Officer for the City of Santa Cruz, dives deep into the ambitious 30-year roadmap to preserve our iconic coastline. She explains how different combinations of coastal adaptations from nature-inspired tech like “living” sand dunes, harder armoring and maybe even offshore artificial reefs might be utilized to combat rising sea levels as they bring in massive wave energy and swallow our shores. We also explore the possible future of "managed retreat"—the difficult conversation about relocating infrastructure before it falls into the sea. Even with the city attempting to proactively manage our coastline, is a 30-year plan enough to save West Cliff, or is time slipping away too quickly?

Ever wonder who’s behind the new trails you hike or the wildlife crossings you drive over? Eric Lombardo, the Land Trust of Santa Cruz County's Director of External Affairs, joins us to pull back the curtain on how conservation actually works in our backyard. From public farms to wildfire-resilient forests, we discuss how protecting the 831 isn’t just about 'keeping people out,' it’s about inviting the community in. Tune in for a blueprint on how we can save our ecosystems, promote community, and still have a place to play.

Marine ecologist and UC Santa Cruz professor Kristy Kroeker unravels the dramatic chain reactions triggered when the sea gets too hot. From the collapse of California’s iconic kelp forests to the surprising takeover by zombie sea urchins, she reveals how the loss of key predators like the sunflower star can flip entire ecosystems on their head. But this isn’t just a story of loss; it’s also one of action and hope. Kristy spotlights bold, hands-on efforts to bring kelp forests back to life, showing how scientists and local communities are teaming up in creative ways to restore balance beneath the waves. With a deep belief in nature’s resilience, she reminds us that when people come together, real change is possible for our oceans.
