Excerpt from Predicting Equilibrium Moisture Content of Some Foliar Forest Litter in the Northern Rocky Mountains Foliar litters consisting of grasses, deciduous leaves, and conifer needles were collected in western Montana and northern Idaho for study. One sampling was done in the fall after the current-year leaf and needle cast, col leeting only the recently cast dead foliar litter. Another sampling was done in the late spring collecting just the weathered foliar litter. The general areas of sampling are shown in figure 1, with the following specific collections: western white pine (pinus monticola Dougl.) at the Priest River Experimental Forest in northern Idaho; lodgepole pine (pinus contorta Dougl.) and Douglas-fir (pseudotsuga menziesii [mirb.] Franco), in the headwater drainages of fish Creek in Montana; Engelmann spruce (picea engel mannii Parry), subalpine fir (abies lasiocarpa [hook] N western redcedar (thuja plicata Bonn), and grand fir (abies grandis [dougl.] in the general area of the Powell Ranger District in Idaho. Litter samples col lected in the vicinity of Missoula, mt, were ponderosa pine (pinus ponderosa Laws), quaking aspen (populus tremuloides western larch (larix occidentalis and cheatgrass (bromus tectorum The fuels were brought to the Intermountain Fire Sciences Labora tory in Missoula, mt, where they were mechanically sorted, cleaned without washing, and placed in cool, dry storage until the testing was done.

Excerpt from Timelag and Equilibrium Moisture Content of Ponderosa Pine Needles Sorption studies of ponderosa pine (pinus ponderosa Laws.) needles and litter beds of current year cast show a shorter response time and lower equilibrium moisture contents than most other conifer needle data in the literature. For conditions below fiber saturation, the response time is described best by considering the time for 95 percent of the total change in moisture content. Equilibrium moisture content can be esti mated by an equation based on temperature and humidity, but type of vegetation must be considered. Analysis of moisture response at the test conditions indicates that the moisture diffusivity of the needles and beds remains nearly constant for both adsorption and desorption.

Excerpt from Watershed Management Problems in the Northern Rocky Mountain Region It also contains large areas of range land where many livestock and big game animals graze. The method of managing these forests and ranges can have far reaching effects upon the condition of the vegetation and soil, and, hence, upon the quality, amount, and rate of water delivered to creeks and rivers. Since 1905, when the national forest systefi was created, methods of managing the timber and forage resources have been improved. Most of these improvements were developed mainly in the interest of better production of timber and forage. Few were directed specifically at betterment of watershed conditions although some have effected improvement incidentally. Management problems concerning the influence of various resource use activities on water and soil continue to arise. Some of these problems involve methods of main taining effective control of water and soil movement under continued timber harvesting, grazing, and recreational uses. Others are concerned with re storing control over water and soil on watersheds where it has been lost through overuse, abuse, or some catastrophe such as wildfire. Still others involve the management of timber and forage resources to improve water yielding characteristics of watersheds, especially the amount and quality of water and the time of year when it appears as streamflow.

This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

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.
