Book excerpt: Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark pine populations require an understanding of all aspects of seed fate. In this paper, we review the literature on seed dispersal in whitebark pine. Clark's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and ultimately affect the ability of whitebark pine populations to regenerate. We also provide a general overview of the natural histories of the most influential species involved with whitebark pine seed fate: Clark's nutcracker and the pine squirrel.

Book excerpt: Describes a prototype whitebark pine seed scarifier developed by the Missoula Technology and Development Center that allows workers to nick (scarify) seeds three times as fast as if they were doing so by hand, with reduced risk of injury. Populations of whitebark pine have declined over the past century because of white pine blister rust, insect infestations, and fire suppression. Whitebark pine seeds are a favored food of the grizzly bear, a threatened species protected by the Endangered Species Act in the 48 contiguous States. Whitebark pine trees, which may be the only trees growing in some sub-alpine and alpine areas of the northern Rocky Mountains, also catch snow during the winter. The drifts melt more slowly than thinner snowpack in bare areas, extending runoff. The scarifier should help reduce the costs of growing whitebark pine seedlings, possibly allowing more whitebark pines to be planted. Seeds collected from white-bark pine trees resistant to blister rust are germinated in nurseries. The germination rate increases from about 5 percent to 60 percent or more if each seed has a 1-mm-deep nick. Workers can nick about 400 seeds an hour by hand, compared to 1,500 seeds an hour when using the prototype scarifier. The scarifier costs about $1,000 to fabricate. Fabrication drawings will be available from the Missoula Technology and Development Center.

Available in PDF, EPUB and Kindle. Book excerpt: Project Puffin is the inspiringstory of how a beloved seabird was restored to long-abandoned nesting colonies off the Maine coast. As a young ornithology instructor at the Hog Island Audubon Camp, Dr. Stephen W. Kress learned that puffins had nested on nearby islands until extirpated by hunters in the late 1800s. To right this environmental wrong, he resolved to bring puffins back to one such island—Eastern Egg Rock. Yet bringing the plan to reality meant convincing skeptics, finding resources, and inventing restoration methods at a time when many believed in “letting nature take its course.” Today, Project Puffin has restored more than 1,000 puffin pairs to three Maine islands. But even more exciting, techniques developed during the project have helped to restore rare and endangered seabirds worldwide. Further, reestablished puffins now serve as a window into the effects of climate change. The success of Dr. Kress's project offers hope that people can restore lost wildlife populations and the habitats that support them. The need for such inspiration has never been greater.

Book excerpt: The Geology, Ecology, and Human History of the San Luis Valley explores the rich landscapes and diverse social histories of the San Luis Valley, an impressive mountain valley spanning over 9,000 square miles that crosses the border of south-central Colorado and north-central New Mexico and includes many cultural traditions. Twenty-six expert scholars and educators—including geologists, geographers, biologists, ecologists, linguists, historians, sociologists, and consultants—uncover the natural and cultural history of the region, which serves as home to the Sangre de Cristo Mountains, the San Juan Mountains, Great Sand Dunes National Park and Preserve, and the Rio Grande headwaters. The first section, “The Geology and Ecology of the San Luis Valley,” surveys the geomorphology, hydrology, animal and plant life, conservation, management, and mining of the valley’s varied terrain. The second section, “Human History of the San Luis Valley,” recounts the valley’s human visitation and settlement, from early indigenous life to Spanish exploration to Hispanic and Japanese settlements. This section introduces readers to the region’s wide range of religious identities—Catholic, Latter-day Saint, Buddhist, Jehovah’s Witness, Amish, and Mennonite—and diverse linguistic traditions, including Spanish, English, Dutch, Danish, Japanese, and Mayan. The final section, “Travel Itineraries,” addresses recreation, specifically fly-fishing and rock climbing. The book provides a comprehensive overview of the endemic flora and fauna, human history of indigenous lifeways, and diverse settlement patterns that have shaped the region. The Geology, Ecology, and Human History of the San Luis Valley will appeal to students and scholars of geology, ecology, environmental history, and cultural history, as well as residents and tourists seeking to know more about this fascinating and integral part of Colorado and New Mexico.

Book excerpt: Meet the ladies: a flock of smart, affectionate, highly individualistic chickens who visit their favorite neighbors, devise different ways to hide from foxes, and mob the author like she's a rock star. In these pages you'll also meet Maya and Zuni, two orphaned baby hummingbirds who hatched from eggs the size of navy beans, and who are little more than air bubbles fringed with feathers. Their lives hang precariously in the balance-but with human help, they may one day conquer the sky. Snowball is a cockatoo whose dance video went viral on YouTube and who's now teaching schoolchildren how to dance. You'll meet Harris's hawks named Fire and Smoke. And you'll come to know and love a host of other avian characters who will change your mind forever about who birds really are. Each of these birds shows a different and utterly surprising aspect of what makes a bird a bird-and these are the lessons of Birdology: that birds are far stranger, more wondrous, and at the same time more like us than we might have dared to imagine. In Birdology, beloved author of The Good Good Pig Sy Montgomery explores the essence of the otherworldly creatures we see every day. By way of her adventures with seven birds-wild, tame, exotic, and common-she weaves new scientific insights and narrative to reveal seven kernels of bird wisdom. The first lesson of Birdology is that, no matter how common they are, Birds Are Individuals, as each of Montgomery's distinctive Ladies clearly shows. In the leech-infested rain forest of Queensland, you'll come face to face with a cassowary-a 150-pound, man-tall, flightless bird with a helmet of bone on its head and a slashing razor-like toenail with which it (occasionally) eviscerates people-proof that Birds Are Dinosaurs. You'll learn from hawks that Birds Are Fierce; from pigeons, how Birds Find Their Way Home; from parrots, what it means that Birds Can Talk; and from 50,000 crows who moved into a small city's downtown, that Birds Are Everywhere. They are the winged aliens who surround us. Birdology explains just how very "other" birds are: Their hearts look like those of crocodiles. They are covered with modified scales, which are called feathers. Their bones are hollow. Their bodies are permeated with extensive air sacs. They have no hands. They give birth to eggs. Yet despite birds' and humans' disparate evolutionary paths, we share emotional and intellectual abilities that allow us to communicate and even form deep bonds. When we begin to comprehend who birds really are, we deepen our capacity to approach, understand, and love these otherworldly creatures. And this, ultimately, is the priceless lesson of Birdology: it communicates a heartfelt fascination and awe for birds and restores our connection to these complex, mysterious fellow creatures

Book excerpt: A tale of one man's obsession with rainforest jewels, this is the story of an impossible dream: a quest to see every one of the world's most elusive avian gems--a group of birds known as pittas--in a single year. Insightful, compelling, and laugh-out-loud funny, this is more than a book about birds. It's a true story detailing the lengths to which a man will go to escape his midlife crisis. A travelogue with a difference, it follows a journey from the suburban straitjacket of High Wycombe to the steamy, leech-infested rainforests of remotest Asia, Africa, and Australia. Dangerous situations, personal traumas, and logistical nightmares threaten The Jewel Hunter's progress. Will venomous snakes or razor-clawed bears intervene? Or will running out of fuel mid-Pacific ultimately sink the mission? The race is on. . . . If you've ever yearned to escape your day job, wondered what makes men tick, or simply puzzled over how to make a truly world-class cup of tea, this is a book for you.
