This book was released on 2018-09-09 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Cone Production by Upper-Slope Conifers A total of 47 plots have been estab lished and studied since 1961, the majority now providing a 6 - year record of cone production. The location and elevation of these plots, characteristics of the sample trees, and period of observation are listed in table 1. The geographic distribution of study plots is illustrated in figure 1. The majority of plots are for key upper - slope species: Pacific silver fir (12 plots), noble fir (eight plots), mountain hemlock (seven plots), and western white pine (nine plots), one of which was lost to mountain pine beetle 2 years after establishment). The remainder are divided between grand, Shasta red, and subalpine firs and Engelmann spruce. In several instances, plots are located in the same stand, e.g., grand fir, subalpine fir, western white pine, and Engel mann spruce at Big Meadows Creek. No records of cone production by upper-slope Douglas-fir and western hemlock were taken. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: "What are the lives of trees, of conifers, like'. . . How do seedlings establish and develop into saplings? How do some seedlings stay alive for decades, marking time in the deep shade of the forest? How do the distinctive forms of saplings of the different species arise'. . . When, how, and where do cones come from? What is the sex life of a conifer? Where does pollen come from? What does pollen do?" - From the Introduction A comparative account of the coniferous trees indigenous to Northeastern North America Extensively illustrated with full-colour photographs, diagrams, and drawings by the author, Graham R. Powell's Lives of Conifers examines the complex and fascinating life cycles of the 12 coniferous trees that grow naturally in northeastern North America on both sides of the Canada-U.S. border. Tracing their development from seeds and seedlings, to saplings, through the pole stage to maturity, old age, and death, the book is designed to pro-vide a comparison of each species at each stage of life, thus aiding in the recognition and identification of species at all stages of their existence. It includes descriptions of developmental processes and how they differ among the species. The species covered in the book are: the balsam fir, eastern hemlock, tamarack larch, eastern white pine, jack pine, pitch pine, red pine, black spruce, red spruce, white spruce, eastern juniper, and eastern thuja. The book is based almost entirely on what is visible to the careful observer in the forest, and includes only the parts of trees that can be seen above ground. Lives of Conifers will appeal to forest scientists, forestry students, foresters, forest technologists, botanists, horticulturists, arborists, naturalists, and general readers interested in knowing more about their natural surroundings.
