Based on vegetative rather than floral characteristics, this practical guide gives anyone who works with plants the ability to identify weeds before they flower.- A dichotomous key to all the species described in the book is designed to narrow the choices to a few possible species. Identification can then be confirmed by reading the descriptions of the species and comparing a specimen with the drawings and photographs.- A fold-out grass identification table provides diagnostic information for weedy grasses in an easy-to-use tabular key.- Specimens with unusual vegetative characteristics, such as thorns, square stems, whorled leaves, or milky sap, can be rapidly identified using the shortcut identification table.The first comprehensive weed identification manual available for the Northeast, this book will facilitate appropriate weed management strategy in any horticultural or agronomic cropping system and will also serve home gardeners and landscape managers, as well as pest management specialists and allergists.

    Written by experts and endorsed by the American Horticultural Society, this is truly the most comprehensive gardening reference available.

    That’s right: growing more mushrooms may be the best thing we can do to save the environment, and in this groundbreaking text from mushroom expert Paul Stamets, you’ll find out how. The basic science goes like this: Microscopic cells called “mycelium”--the fruit of which are mushrooms--recycle carbon, nitrogen, and other essential elements as they break down plant and animal debris in the creation of rich new soil. What Stamets has discovered is that we can capitalize on mycelium’s digestive power and target it to decompose toxic wastes and pollutants (mycoremediation), catch and reduce silt from streambeds and pathogens from agricultural watersheds (mycofiltration), control insect populations (mycopesticides), and generally enhance the health of our forests and gardens (mycoforestry and myco-gardening).  In this comprehensive guide, you’ll find chapters detailing each of these four exciting branches of what Stamets has coined “mycorestoration,” as well as chapters on the medicinal and nutritional properties of mushrooms, inoculation methods, log and stump culture, and species selection for various environmental purposes. Heavily referenced and beautifully illustrated, this book is destined to be a classic reference for bemushroomed generations to come.

    Seeing Trees celebrates seldom seen but easily observable tree traits and invites you to watch trees with the same care and sensitivity that birdwatchers watch birds. Many people, for example, are surprised to learn that oaks and maples have flowers, much less flowers that are astonishingly beautiful when viewed up close. Focusing on widely grown trees, this captivating book describes the rewards of careful and regular tree viewing, outlines strategies for improving your observations, and describes some of the most visually interesting tree structures, including leaves, flowers, buds, leaf scars, twigs, and bark. In-depth profiles of ten familiar species—including such beloved trees as white oak, southern magnolia, white pine, and tulip poplar—show you how to recognize and understand many of their most compelling (but usually overlooked) physical features.

    Will temperatures rise by 2�C or 8�C over the next hundred years? Will sea levels rise by 2 or 30 feet? The only way that we can accurately answer questions like these is by looking into the distant past, for a comparison with the world long before the rise of mankind.We may currently believe that atmospheric shifts, like global warming, result from our impact on the planet, but the earth's atmosphere has been dramatically shifting since its creation. This book reveals the crucial role that plants have played in determining atmospheric change - and hence the conditions on the planet we know today. Along the way a number of fascinating puzzles arise: Why did plants evolve leaves? When and how did forests once grow on Antarctica? How did prehistoric insects manage to grow so large? The answers show the extraordinary amount plants can tell us about the history of the planet -- something that has often been overlooked amongst the preoccuputations with dinosaur bones and animal fossils.David Beerling's surprising conclusions are teased out from various lines of scientific enquiry, with evidence being brought to bear from fossil plants and animals, computer models of the atmosphere, and experimental studies. Intimately bound up with the narrative describing the dynamic evolution of climate and life through Earth's history, we find Victorian fossil hunters, intrepid polar explorers and pioneering chemists, alongside wallowing hippos, belching volcanoes, and restless landmasses.

    He sets out to explore the many, and particular, ways that he, and we, experience the natural world – beginning face down on the pavement outside his home then moving outwards to garden, local patch, wildlife reserve, craggy coastline and as far afield as the dark hills of Skye. He visits the haunts of famous nature lovers – reaching back to the likes of Charles Darwin, Etta Lemon, Gavin Maxwell, John Clare and Emma Turner – to examine their insatiable curiosity and follow in their footsteps.And everywhere he meets not only nature, but nature lovers of all varieties. The author reveals how our collective relationship with nature has changed over the centuries, what our actions mean for nature and what being a nature lover in Britain might mean today.

    Leopold, expert in horticulture, botany, forestry, and ecology No other single volume on native plants has such comprehensive horticultural coverage as Native Plants of the Northeast: A Guide for Gardening and Conservation. Nearly seven hundred species of native trees, shrubs, vines, ferns, grasses, and wildflowers from the northeastern quarter of the United States and all of eastern Canada are included. Each plant description includes information about cultivation and propagation, ranges, and hardiness. An appendix recommends particular plants for difficult situations, as well as attracting butterflies, hummingbirds, and other wildlife.

    The Rocky Mountains are home to a diversity of plant species that have helped native peoples and settlers survive through the centuries. EDIBLE AND MEDICINAL PLANTS OF THE ROCKIES describes 333 common trees, shrubs, flowers, ferns, mosses and lichens that have been used by people from ancient times to the present. This comprehensive guide contains: * More than 700 color photographs and illustrations * An introduction explaining the use of wild plants, including gathering, preparing and cooking * Food, medicinal and other uses for each species * Clear descriptions of the plants and where to find them * Warnings about plant allergies, poisons and digestive upsets * A special section at the end detailing 46 of the more common poisonous plants in the Rockies region.

    Since that time he has answered thousands of questions about birds, both at his store and while walking down the aisles of the supermarket. The questions have ranged from inquiries about individual species ("Are flamingos really real?") to what and when to feed birds ("Should I bring in my feeders for the summer?") to the down-and-dirty specifics of backyard birding ("Why are the birds dropping poop in my pool?"). Answering the questions has been easy; keeping a straight face has been hard.Why Don't Woodpeckers Get Headaches? is the solution for the beginning birder who already has a book that explains the slight variation between Common Ground-Doves and Ruddy Ground-Doves but who is really much more interested in why birds sing at 4:30 A.M. instead of 7:00 A.M., or whether it's okay to feed bread to birds, or how birds rediscover your feeders so quickly when you've just filled them after a long vacation. Or, for that matter, whether flamingos are really real.

    They attracted followers ranging from Thomas Jefferson, who laid out mastodon bones on the White House floor, to twentieth-century doctors who used their knowledge of new species to conquer epidemic diseases. Acclaimed science writer Richard Conniff brings these daredevil "species seekers" to vivid life. Alongside their globe-spanning tales of adventure, he recounts some of the most dramatic shifts in the history of human thought. At the start, everyone accepted that the Earth had been created for our benefit. We weren't sure where vegetable ended and animal began, we couldn't classify species, and we didn't understand the causes of disease. But all that changed as the species seekers introduced us to the pantheon of life on Earth—and our place within it.

    In this beautiful new one-volume edition, modern readers are introduced to one of the best nature writers of the last century. More than one hundred of the original illustrations by Paul Landacre highlight the eloquent and entertaining accounts of American trees. As we read Peattie's descriptions, we catch glimpses of our country's history and past daily life that no textbook could ever illuminate so vividly.Here you'll learn about everything from how a species was discovered to the part it played in our country’s history. Pioneers often stabled an animal in the hollow heart of an old sycamore, and the whole family might live there until they could build a log cabin. The tuliptree, the tallest native hardwood, is easier to work than most softwood trees; Daniel Boone carved a sixty-foot canoe from one tree to carry his family from Kentucky into Spanish territory. In the days before the Revolution, the British and the colonists waged an undeclared war over New England's white pines, which made the best tall masts for fighting ships. It's fascinating to learn about the commercial uses of various woods -- for paper, fine furniture, fence posts, matchsticks, house framing, airplane wings, and dozens of other preplastic uses. But we cannot read this book without the occasional lump in our throats. The American elm was still alive when Peattie wrote, but as we read his account today we can see what caused its demise. Audubon's portrait of a pair of loving passenger pigeons in an American beech is considered by many to be his greatest painting. It certainly touched the poet in Donald Culross Peattie as he depicted the extinction of the passenger pigeon when the beech forest was destroyed. 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.
