Yellowstone National Park was once home to an abundance of wild wolves - but park rangers killed the last of their kind in the 1920s. Decades later, the rangers brought them back, with the first wolves arriving from Canada in 1995. This is the incredible true story of one of those wolves.

Empire of Shadows is the epic story of the conquest of Yellowstone, a landscape uninhabited, inaccessible, and shrouded in myth in the aftermath of the Civil War. In a radical reinterpretation of the 19th century West, George Black casts Yellowstone's creation as the culmination of three interwoven strands of history.

Yellowstone is a land of extreme diversity. Nowhere else will you find wolves, bison, and grizzlies living among the largest concentration of hot springs and geysers in the world. The park’s 2.2 million acres is an incongruous landscape of bubbling hot, lunar-like geothermal features, lush green rolling meadowlands, snow covered mountain peaks, colorful canyons, waterfalls, lakes and untamed rivers. It is a park so large, so complex and so fascinating it seems fitting that it owns the title as our world’s first national park! Travel Audios’ park approved audio tour will help you understand what you are seeing and smelling! It is not a mile-by-mile guide; it can be listened to anywhere. It features an impressive group of knowledgeable Park Ranger geologists, biologists and naturalists who explain the geological processes that created the landscape and why this area in Wyoming is such a geothermal hot spot. They’ll tell you about their studies and observations of the park’s wildlife and their experience with massive forest fires.

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.

This best-selling, groundbreaking exploration of the Far North is a classic of natural history, anthropology, and travel writing.

From a Wall Street Journal best-selling author and wildlife photographer whose award-wining Yellowstone imagery is displayed in the Smithsonian.

From award-winning writer Leila Philip, Beaverland is a masterful work of narrative science writing, a book that highlights, though history and contemporary storytelling, how this weird rodent plays an oversized role in American history and its future. She follows fur trappers who lead her through waist high water, fur traders and fur auctioneers, as well as wildlife managers, PETA activists, Native American environmental vigilantes, scientists, engineers, and the colorful group of activists known as beaver believers.

Visiting it almost daily for one year to trace nature's path through the seasons, he brings the forest and its inhabitants to vivid life. Each of this audiobook's short chapters begins with a simple observation: a salamander scuttling across the leaf litter; the first blossom of spring wildflowers.

A Natural History of North American Trees gives us a picture of life in America from its earliest days to the middle of the last century. The information is always interesting, though often heartbreaking. While Peattie looks for the better side of man's nature, he reports sorrowfully on the greed and waste that have doomed so much of America's virgin forest.

Interweaving her own first-hand experiences in the field with the compelling research of premier scientists, Goodall illuminates the heroic efforts of dedicated environmentalists and the truly critical need to protect the habitats of these beloved species. At once a celebration of the animal kingdom and a passionate call to arms, Hope for Animals and Their World presents an uplifting, hopeful message for the future of animal-human coexistence.

It's accepted wisdom today that human beings have permanently damaged the natural world, causing extinction, deforestation, pollution, and of course climate change. But in Inheritors of the Earth, biologist Chris Thomas shows that this obscures a more hopeful truth - we're also helping nature grow and change. Human cities and mass agriculture have created new places for enterprising animals and plants to live, and our activities have stimulated evolutionary change in virtually every population of living species.

From one of the finest scientists and writers of our time comes an engaging record of a life spent in close observation of the natural world, one that has yielded marvelous, mind-altering insight and discoveries. In essays that span several decades, Bernd Heinrich finds himself at his beloved camp in Maine, plays host to annoying visitors from Europe (the cluster fly) and more helpful guests from Asia (ladybugs), and unravels the far-reaching ecological consequences of elephants in Botswana bruising mopane trees.

In this poetic audiobook, hear the words of legendary outdoorsman John Muir's entreaty to the American people imploring them to develop, as he did, a connection to their national parks. An ardent outdoorsman, a gifted writer, a dedicated preservationist, and a spiritual beacon, John Muir worked in his life and in his writing to inspire everyone to find a love for the wilderness and to become invested in its preservation.

In One Wild Bird at a Time, Heinrich returns to his great love: close, day-to-day observations of individual wild birds. Heinrich's observations lead to fascinating questions - and sometimes startling discoveries. A great crested flycatcher bringing food to the young acts surreptitiously and is attacked by the mate. Why? A pair of northern flickers hammering their nest-hole into the side of Heinrich's cabin delivers the opportunity to observe the feeding competition between siblings.

Thoreau gives an account of three canoe and hiking journeys - by himself and with others - through the mostly uninhabited forests of Maine in the 1850s. Identifying birds, trees and plants by their botanical as well as their common names, he also records the Indian names of lakes, rivers and plants. He investigates the connections between waterways and trails, and provides detail on camping, fishing and hunting in the woods, using whatever is at hand. Extolling the beauty of the wilds that he encounters, Thorough’s narrative is also imbued with elements of his philosophy.

From the author of Apocalyptic Planet, an unsparing, vivid, revelatory travelogue through prehistory that traces the arrival of the First People in North America 20,000 years ago and the artifacts that enable us to imagine their lives and fates. This book upends our notions of where these people came from and who they were.

The bald eagle is regal but fearless, a bird you’re not inclined to argue with. For centuries, Americans have celebrated it as “majestic” and “noble,” yet savaged the living bird behind their national symbol as a malicious predator of livestock and, falsely, a snatcher of babies.

When President Thomas Jefferson acquired the Louisiana Purchase - the vast, unknown lands between the Mississippi River and the Rocky Mountains, from Canada to the Gulf of Mexico - he promptly established an expedition to map America's new frontier. Meriwether Lewis and William Clark outfitted the "Corps of Discovery," and on May 14, 1804, 45 men in 3 boats set off up the Mississippi.

For millennia, lions, tigers, and their man-eating kin have kept our dark, scary forests dark and scary, and their predatory majesty has been the stuff of folklore. But by the year 2150 big predators may only exist on the other side of glass barriers and chain-link fences. Their gradual disappearance is changing the very nature of our existence. We no longer occupy an intermediate position on the food chain; instead we survey it invulnerably from above - so far above that we are in danger of forgetting that we even belong to an ecosystem.

Are there any genuinely wild places left in Britain and Ireland? Or have we tarmacked, farmed and built ourselves out of wildness? In his vital, bewitching, inspiring classic, Robert Macfarlane sets out in search of the wildness that remains.
