Manual del contrafuego. EL manejo del fuego en la extinción de incendios forestales. 2ª ed. (Spanish Edition)

Practical, easy to understand, and up-to-date, INTRODUCTION TO FORESTRY SCIENCE, Third Edition provides readers with a comprehensive overview of the principles and practices of forest management that are commonly practiced in the United States. Appropriate for anyone interested in forestry or natural resources, this book is filled with visual aids and tools as well as career profiles which give readers an overview of what it might be like to work in the forest industry and demonstrate how concepts are applied in the real world. In addition to covering the basics of the biological processes necessary for the creation of forests, topics such as the economic impact of forests on the U.S. economy, government historical events and policies, regional differences in forests and forest management, and laws and regulations that govern the use of forests are presented.

Bears and bureaucrats, timber and telephone lines, poaching and predators, fires and families -- all these play a part in this fascinating and long-overdue study of Canadas National Park wardens. The Warden Service has been integral to Canadas National Parks from their earliest days. First established in Rocky Mountains Park (now Banff National Park) in 1909, the position of Fire and Game Guardian was the precursor of todays National Park Warden, whose duties now include resource management, law enforcement and public safety. Robert Burns traces the growth of the warden service from here, its formative years, and goes on to show how the role changed and developed according to the expanding park system, altered societal expectations, and technological change. Guardians of the Wild is a study of real people and their trials, triumphs and tragedies. This book creates a complete history where before there existed only sketchy accounts of single individuals and incidents. The need for such an account is undeniable; well-known historian Simon Evans describes this story as "one which deserves to be heard." Both a tribute to the enormous devotion to duty and dedicated labours of the park wardens, and a well-researched factual account of how our National Parks evolved, Guardians of the Wild is a singular study of the historical evolution of protection and management inside Canadas National Parks.
