We are taking a break over the holidays in order to finish up our series about national parks. We’ll be back in your feed on January 7 with a visit to Glacier Bay National Park in southeast Alaska. We’ll learn how the trickles of chilly glacial meltwater are creating a flourishing ecosystem.

But in the meantime, I wanted to share an episode from a podcast I think you’ll really like called How Wild. It’s from our friends at KALW Public Media and the NPR Network. The podcast looks at the meaning of wilderness, sixty years since the passage of the Wilderness Act of 1964.

The law set aside areas within national parks and forests and other federal public lands for an extra level of protection. These wilderness areas have to be “undeveloped” and “natural” and they have to have opportunities for “primitive, unconfined recreation” and “solitude.”

But so much has changed since the passage of the Wilderness Act. In this episode, host Marissa Ortega-Welch looks at solitude and what that means these days with so many people hitting the trails.

It started as a glacier. Then, about 13,000 years ago, it was a trickle, then a stream, and eventually a rushing river meandering through the Olympic Peninsula. For thousands of years, life thrived off the ecosystem served by the Elwha River that fed into to the Strait of Juan De Fuca. Then it stopped. A century ago, a dam was built to harness the power of the water and convert it into electricity. The salmon that the Lower Elwha Klallam Tribe relied on were cut off from their spawning grounds.

Ten years ago, that dam was taken down. In this special reprise episode, we look at the impact of the dam removal and how life in and around the Elwha is fighting its way back.

Nature writer Leigh Ann Henion has spent countless hours uncovering mysteries of the darkness that unfold while we’re asleep. She’s explored bats, moths, glow worms, spotted salamanders, and she’s written a new book about it called Night Magic: Adventures Among Glowworms, Moon Gardens, and Other Marvels of the Dark.

Today, Chris talks with Leigh Ann Henion about what we can find in the darkness and how we can preserve it, even from our own back porch.

Once a year they come out, by the thousands. Fireflies. But these aren’t just any fireflies. These are Photinus Carolinas, also known as synchronous fireflies They blink on and off together. It’s an amazing site. On this episode, I head to Great Smoky Mountains National Park to experience the synchronous fireflies and learn how light from human development is threatening the future of these delicate, glowing insects and what the park is doing to try to protect them.

Four times in the past decade Lake Abert has completely dried up, a barren lakebed encrusted with salt. Salt lakes are among the world's most threatened ecosystems. Lack of water could lead to many of these lakes permanently drying up in the American West.

But there is one tiny bird that could change all that. The Wilson’s Phalarope depends on salt lakes on their 6500-mile migration between North and South America. There is a movement to get the phalarope listed as a threatened species by the federal government as a way to protect the habitat they need to survive.

Caroline Tracey is an environment reporter who grew up in the American West - a place that flows through so much of her work. She recently signed a book deal for a memoir about her love of salt lakes - these often-ignored ecosystems that are crucial to the world’s water cycle, migratory bird populations, and human health.

In the Florida Everglades, the Burmese python is an invasive species that's close to triggering an ecological collapse. We'll head out with python hunters who track down these massive snakes for a bounty. Then we wade through the waste deep murky waters of the Everglades to see what researchers are learning about Burmese pythons in their waning hopes to remove them from this fragile tropical wilderness.

Cuyahoga Valley National Park is nestled between Akron and Cleveland, Ohio. It once was an industrial wasteland, filled with debris from the nearby auto factories. The Cuyahoga river was so polluted that it literally caught fire. That fire was a moment that sparked an environmental movement. But I'm headed upstream. I'm going to follow the river and its story from its grim past to becoming a national park.

We’ll look at how a toxic dump was transformed into a national park and a thriving ecosystem, teaming with life.
