Imagine raising an orphaned bear cub, carefully reintroducing her to the wild, then being welcomed back, almost daily, to observe her wild world for more than 17 years. Imagine visiting her in her feeding spots, watching her with her mates and her young, peering into her den, and, over time, observing the lives of all the other wild bears in her territory and surrounding ones. That is what happened to Ben Kilham.

Four decades ago, the areas around Yellowstone and Glacier National Parks sheltered the last few hundred surviving grizzlies in the lower 48 states. Protected by the Endangered Species Act, their population has surged to more than 1,500, and this burgeoning number of grizzlies now collides with the increasingly populated landscape of the 21st-century American West. Montana journalist Robert Chaney chronicles the resurgence of this charismatic species against the backdrop of the country's long history with the bear.

John Muir (1838 -1914) was an influential Scottish-American naturalist, author, environmental philosopher, and early advocate for the preservation of wilderness areas in the United States. In the late 1800s, Muir made several trips to the relatively unexplored territory of Alaska. Travels in Alaska, originally published in 1915, describes the beauty of the Alaskan wilderness and its inhabitants as observed during his travels between 1879 and 1890. In poetic prose, he describes the area’s magnificent glaciers and its animals like bears, bald eagles, wolves and whales.

First published in 1949 and praised in the New York Times Book Review as "full of beauty and vigor and bite", A Sand County Almanac combines some of the finest nature writing since Thoreau with an outspoken and highly ethical regard for America's relationship to the land.

A riveting history of America's most beautiful natural resources, The Quiet World documents the heroic fight waged by the U.S. federal government from 1879 to 1960 to save wild Alaska - ;Mount McKinley, the Tongass and Chugach national forests, Gates of the Arctic, Glacier Bay, Lake Clark, and the Coastal Plain of the Beaufort Sea, among other treasured landscapes - from the extraction industries.

In Eager, environmental journalist Ben Goldfarb reveals that our modern idea of what a healthy landscape looks like and how it functions is wrong, distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of "Beaver Believers" recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them.

In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we've learned of these key migrations is nothing short of extraordinary. This breathtaking work of nature writing also introduces listeners to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

When South African conservationist Lawrence Anthony was asked to accept a herd of "rogue" wild elephants on his Thula Thula game reserve in Zululand, his common sense told him to refuse. But he was the herd's last chance of survival: they would be killed if he wouldn't take them. In order to save their lives, Anthony took them in. In the years that followed he became a part of their family. And as he battled to create a bond with the elephants, he came to realize that they had a great deal to teach him about life, loyalty, and freedom.

The real stories behind the scenery of America’s national parks. For 12 years, Andrea Lankford lived in the biggest, most impressive national parks in the world, working a job she loved. She chaperoned baby sea turtles on their journey to sea. She pursued bad guys on her galloping patrol horse. She jumped into rescue helicopters bound for the heart of the Grand Canyon. She won arguments with bears. She slept with a few too many rattlesnakes. Hell yeah, it was the best job in the world! Fortunately, Andrea survived it.

In this riveting real-life adventure, Mark and Delia Owens tell the dramatic story of their last years in Africa, fighting to save elephants, villagers, and - in the end - themselves. The award-winning zoologists and pioneering conservationists describe their work in the remote and ruggedly beautiful Luangwa Valley, in northeastern Zambia. There they studied the mysteries of the elephant population’s recovery after poaching, discovering remarkable similarities between humans and elephants.

For listeners of Jane Goodall and Lawrence Anthony, this up-close, captivating look at bears traces our complex relationship to the animal throughout history. On Being a Bear draws on history, legends, scientific studies, and the author’s 30 years of observing bears around the world to offer a richly detailed biography of these iconic animals, including the many ways bears have figured in our lives and imaginations.

A hilarious, heartwarming, and heartbreaking memoir by the chief wildlife ranger in the number one most popular family vacation destination in the USA, the Great Smoky Mountains National Park. For over 30 years, Kim DeLozier acted as a referee in the wild, trying to protect millions of park visitors from one of the densest populations of wild black bears in America - and the bears from tourists who get too close.

Intelligent, majestic, and loyal, with lifespans matching our own, elephants are among the greatest of the wonders gracing the African wilds. Yet in the 1970s and 1980s, about 1,000 of these captivating creatures were slaughtered in Zambia each year, killed for their valuable ivory tusks. When biologists Mark and Delia Owens, residing in Africa to study lions, found themselves in the middle of a poaching fray, they took the only side they morally could: that of the elephants.

When the fishing vessel La Conte sinks suddenly at night in 100-mile-per-hour winds and record 90-foot seas during a savage storm in January 1998, her five crewmen are left to drift without a life raft in the freezing Alaskan waters and survive as best they can. One hundred fifty miles away, in Sitka, Alaska, an H-60 Jayhawk helicopter lifts off from America's most remote Coast Guard base in the hopes of tracking down an anonymous Mayday signal. A fisherman's worst nightmare has become a Coast Guard crew's desperate mission.
