Book Description
Excerpt from U. S. Forest Service Research Pater Int-16 to Int-30, 1965-1966 Overstocking threatens production on more than 1 million acres of western larch (larix occidentalis Nutt.) in the northern Rocky Mountains Dense stands have developed on favorable seedbeds found on many large burns and cutover areas in this region. The great number of stems in many of these stands precludes Optimum growth and development of individual trees because growth is being distributed over too many stems per acre. These trees are likely to remain overcrowded for long periods if stands are unmanaged. Trees in such stands will not reach commercially desirable size within a reasonable time. The obvious solution to the over stocking problem is thinning. Few western larch stands have been thinned, and little information has been published on thinnings in larch. Forest managers are now guided principally by information developed in other forest types. This paper reports results of two western larch thinning studies located on the lo10 National Forest in western Montana. Briefly, the results show that diameter, basal area, height, and cubic-foot volume growth can be improved by thinning. Concentrating growth on fewer trees per acre will produce larger trees earlier.

Book Description
Fire managers need better estimates of fuel loading so they can more accurately predict the potential fire behavior and effects of alternative fuel and ecosystem restoration treatments. This report presents a new fuel sampling method, called the photoload sampling technique, to quickly and accurately estimate loadings for six common surface fuel components (1 hr, 10 hr, 100 hr, and 1000 hr downed dead woody, shrub, and herbaceous fuels). This technique involves visually comparing fuel conditions in the field with photoload sequences to estimate fuel loadings. Photoload sequences are a series of downward-looking and close-up oblique photographs depicting a sequence of graduated fuel loadings of synthetic fuelbeds for each of the six fuel components. This report contains a set of photoload sequences that describe the range of fuel component loadings for common forest conditions in the northern Rocky Mountains of Montana, USA to estimate fuel loading in the field. A companion publication (RMRS-RP-61CD) details the methods used to create the photoload sequences and presents a comprehensive evaluation of the technique.

Book Description
"Southern forests provide innumerable benefits. Forest scientists, managers, owners, and users have in common the desire to improve the condition of these forests and the ecosystems they support. A first step is to understand the contributions science has made and continues to make to the care and management of forests. This book represents a celebration of past accomplishments, summarizes the current state of knowledge, and creates a vision for the future of southern forestry research and management. Chapters are organized into seven sections: "Looking Back," "Productivity," "Forest Health," "Water and Soils," "Socioeconomic," "Biodiversity," and "Climate Change." Each section is preceded by a brief introductory chapter. Authors were encouraged to focus on the most important aspects of their topics; citations are included to guide readers to further information."

Book Description
Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.
