Excerpt from Watershed Management Problems in the Northern Rocky Mountain Region<br/><br/>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.

Paperback. Zustand: New. Print on Demand. This book is a detailed analysis of the watershed management problems found in the Northern Rocky Mountain region. The Northern Rocky Mountain region is made up of portions of Idaho, Montana, South Dakota, and Wyoming. The author, a forester in the US Forest Service, writes that over 166 million acres in this region drain into the Columbia and Missouri Rivers. These rivers provide power and irrigation for a large expanse of the United States. However, the way humans use the land in the Northern Rocky Mountain area directly affects the flow of water in these rivers and can create problems such as flooding, erosion, and a decrease in water quality. The problems that plague the region are examined in detail, including the various ways that forests and grazing lands can better be managed to reduce erosion and prevent flooding. The author also discusses methods that can be used to improve water quality and quantity. The book concludes by highlighting the value of the Northern Rocky Mountain region as it relates to water resources and the impact that humans can have on these resources.
