Geographic Variation in Forest Trees is the first book to examine this subject from a world-wide perspective. Following a historical review, the author discusses population genetic theory and genetic systems of native North American tree species as they interact with environments in the major climatic regions in the world. He then demonstrates how this knowledge is used to guide seed zoning and seed transfer in silviculture, basing much of his discussion on models developed in Scandinavia and North America. In the final chapter, the author addresses the issue of genetic conservation -- a subject of great concern in the face of accelerated forest destruction, industrial pollution, and climatic change.
This comprehensive, well-researched book makes a significant contribution to the knowledge of one of our most important renewable natural resources.
There are redwoods in California that were ancient by the time Columbus first landed, and pines still alive that germinated around the time humans invented writing. There are Douglas firs as tall as skyscrapers, and a banyan tree in Calcutta as big as a football field.
From the tallest to the smallest, trees inspire wonder in all of us, and in The Tree, Colin Tudge travels around the world—throughout the United States, the Costa Rican rain forest, Panama and Brazil, India, New Zealand, China, and most of Europe—bringing to life stories and facts about the trees around us: how they grow old, how they eat and reproduce, how they talk to one another (and they do), and why they came to exist in the first place. He considers the pitfalls of being tall; the things that trees produce, from nuts and rubber to wood; and even the complicated debt that we as humans owe them.
Tudge takes us to the Amazon in flood, when the water is deep enough to submerge the forest entirely and fish feed on fruit while river dolphins race through the canopy. He explains the “memory” of a tree: how those that have been shaken by wind grow thicker and sturdier, while those attacked by pests grow smaller leaves the following year; and reveals how it is that the same trees found in the United States are also native to China (but not Europe).
From tiny saplings to centuries-old redwoods and desert palms, from the backyards of the American heartland to the rain forests of the Amazon and the bamboo forests, Colin Tudge takes the reader on a journey through history and illuminates our ever-present but often ignored companions.
As vividly as John Krakauer puts readers on Everest, John Vaillant takes us into the heart of North America's last great forest.
Temperate and Boreal Rainforests of the World brings together leading scientists from around the world to describe the ecology and conservation of these lesser-known rainforests in an attempt to place them on par with tropical rainforests in conservation efforts. The book summarizes major scientific findings presents new computer models that were used to standardize rainforest definitions identifies regions previously not widely recognized as rainforest provides the latest estimates on rainforest extent and degree of protection explores conservation strategies
The book ends with a summary of the key ecological findings and outlines an ambitious vision of how we can conserve and manage the planet's remaining temperate and boreal rainforests in a truly ecological way that is better for nature, the climate, and ultimately our own welfare.
Temperate and Boreal Rainforests of the World is a call to action for an accord to protect the world's rainforests. It offers a global vision rooted in ecological science but written in common language useful for governments, decision makers, and conservation groups concerned about the plight of these remarkable forests.
One of the world's experts on how trees chemically affect the environment, Canadian scientist Diana Beresford-Kroeger is on a mission to save the planet- one newly planted tree at a time. In this new book, she skillfully weaves together ecology, ethnobotany, horticulture, spirituality, science, and alternative medicine to capture the magic spell that trees cast over us, from their untapped ecological and pharmaceutical potential to the roles they have played in our cultural heritage. Trees not only breathe and communicate; they also reproduce, provide shelter, medicine, and food, and connect disparate elements of the natural world. In celebrating forests' function and beauty, Beresford-Kroeger warns what a deforested world would look like. Her revolutionary bioplan proposes how trees can be planted in urban and rural areas to promote health and counteract pollution and global warming, maintaining biodiversity in the face of climate change.
Presented in short interconnected essays, The Global Forest draws from ancient storytelling traditions to present an unforgettable work of natural history. Beresford-Kroeger is an imaginative thinker who writes with the precision of a scientist and the lyricism of a poet. Her indisputable passion for her subject matter will inspire readers to look at trees with newfound awe.
From the Hardcover edition.
Through identification keys, descriptions, and life histories of the conifer tree species, the author emphasizes how different these plants are both biologically and evolutionarily from the hardwoods we also call "trees." Following this introduction to the essential conifers, the author's perceptive insights expand to include the interactions of conifers with other plants, fungi, mammals, birds, and amphibians.
The second edition, enriched by new illustrations by the author of woodland features and creatures, updates the text to include new topics including mycorrhizal fungi, soil, woodlice, bats, and invasive insects such as the hemlock woolly adelgid. Emphasis is given to the very real human-driven impacts that threaten the species that live in and depend on the vital and complex forest ecosystem. Pielou provides us with a rich understanding of the northern forests in this work praised for its nontechnical presentation, scientific objectivity, and original illustrations.
The Red Hills woodlands were thought of primarily as a healthful refuge for northern industrialists in the early twentieth century. When notable wildlife biologist Herbert Stoddard arrived in 1924, he began to recognize the area's ecological value. Stoddard was with the federal government, but he drew on local knowledge to craft his land management practices, to the point where a distinctly southern, agrarian form of ecological conservation emerged. This set of practices was in many respects progressive, particularly in its approach to fire management and species diversity, and much of it remains in effect today.
Using Stoddard as a window into this unique conservation landscape, Conserving Southern Longleaf positions the Red Hills as a valuable center for research into and understanding of wildlife biology, fire ecology, and the environmental appreciation of a region once dubbed simply the "pine barrens."
