Western North American Juniperus Communities

In North America, Juniperus woodlands occupy approximately 55 million hectares, an area larger than the state of Texas. This title addresses various aspects of the biology, ecology, and management of Juniperus woodlands and savannas, synthesizing past and current research findings as well as proposed research. The book provides ecologists, land managers, and foresters with a solid foundation in Juniperus ecosystems, enabling them to manage the communities for maximum sustained productivity and diversity.

This book is mostly about the plant communities of a very large area in south-central Texas called the Edwards Plateau where a number of plant communities come together. This area is a physiographicregion and a confluence of many divergent and discontinuous communities. Many of the plant communities in this area have never been described and nothing is published about them and I plan to rectify this. Work on the species and communities of this area are scattered throughout the literature. I plan to bring this work together in one place. Much of what has been said in the past about this large general region of Texas is hearsay or speculation and much is incorrect and will be corrected here. Communities and factors responsible for allowing the communities to develop and persist will be examined including species present, light levels, herbivory, fire frequency, availability of soil water and soil nutrients. The limits of plant species and communities in this area are difficult to understand including why a community is located where it is and what caused it to be there, how it interacts with other communities and the factors or condition that control the distribution and how the communities interact will be carefully examined and explained in light of recent research.

Includes our current knowledge of the invasion or encroachment and cause of population growth and spread of some dry land, arid zone woody legumes. Community structure, population growth, and competition of these woody legumes will also be examined. These species and ecosystems are both extensive and dynamic. They occur worldwide, but mainly in the arid zones of the tropics and sub-tropics. The cause of the growth and spread of these species and communities has long been claimed to be caused by distal factors rather than proximal ones. However, these species appear to be influenced and perhaps controlled by anthropogenic factors, specifically grazing and fire or lack of fire. Their overall worldwide distribution has probably changed little in the recent past, but their populations have expanded into grasslands and their density has increased in many places. Some associated communities have shown dramatic changes in response to recent large-scale droughts and the loss of most of the dominant overstory species. However, changes in the woody legume communities and their species are generally unknown. ​

Black-tailed and mule deer represent one of the largest distributions of mammals in North America and are symbols of the wide-open American West. Each chapter in this book was authored by the world’s leading experts on that topic. Both editors, James R. Heffelfinger and Paul R. Krausman, are widely published in the popular and scientific press and recipients of the O. C. Wallmo Award, given every two years to a leading black-tailed and mule deer expert who has made significant contributions to the conservation of this species. In addition, Heffelfinger has chaired the Mule Deer Working Group sponsored by the Western Association of Fish and Wildlife Agencies for more than 15 years. This working group consists of the leading black-tailed and mule deer experts from each of 24 states, provinces, and territories in western North America, putting them at the forefront of all conservation and much of the research on this species. The book represents all current knowledge available on these deer, including how changing conditions such as fires, habitat alteration and loss, disease, climate change, socio-economic forces, energy development, and other aspects are influencing their distribution and abundance now and into the future. It takes a completely fresh look at all chapter topics. The revisions of distribution, taxonomy, evolution, behavior, and new and exciting work being done in deer nutrition, migration and movements, diseases, predation, and human dimensions are all assembled in this volume. This book will instantly become the foundation for the latest information and management strategies to be implemented on the ground by practitioners and to inform the public. Although this book is about deer, the topics discussed influence most terrestrial wildlife worldwide, and the basic concepts in many of the chapters are applicable to other species.

A coherent, readable summary of the technical information available on savannas, barrens and rock outcrop plant communities.

Global Application of Prescribed Fire provides a first-hand perspective of the various methods and ways people around the world view and use prescribed fire. It covers the logistics, constraints and social dynamics surrounding the intentional use and application of fire by humans, and demonstrates how, why, when and where prescribed fire is used in different regions. Written by international experts, the book has four key objectives: explore new techniques, ideas and thoughts on how to apply prescribed fire from a global perspective; provide regional case studies covering issues that may constrain or enhance prescribed fire projects; stimulate cross-cultural conversations about how fires function in ecosystems; and relate prescribed fire to wildfire regimes with implications for protecting life and property, as well as sustaining local fire cultures and unique fire-dependent flora and fauna. Global Application of Prescribed Fire enhances our understanding and knowledge about the application of prescribed fire. This comprehensive book will provide fire practitioners, researchers, agencies and policymakers with key ecological and managerial insight of how prescribed fires are conducted around the globe.

Bringing together ecology and management of invasive plants within natural and agricultural ecosystems, this book bridges the knowledge gap between the processes operating within ecosystems and the practices used to prevent, contain, control and eradicate invasive plant species. The book targets key processes that can be managed, the impact of invasive plants on these ecosystem processes and illustrates how adopting ecologically based principles can influence the ecosystem and lead to effective land management.
