内容説明
Rocky Mountain National Park was established in 1915, one year before the creation of the National Park Service. The mandate of the National Park Service is to preserve and protect areas of exquisite beauty and cultural value for the benefit and enjoyment of future generations. National parks mean many things to many people, and, in often stirring words, a National Parks and Conservation Association report states the National Park System is a magnificent and uniquely American gift to the American people and the world. In the early years of the Service, park superintendents actively promoted and developed parks to accommodate visitors. Then, as now, parks represented a democratic ideal, that even the greatest treasures should be available to all. Seventy five years ago, however, park managers saw little need for active management of natural resources, unless it was to enhance visitors' experience. And few managers saw the need for a stable and independent research program on which to base management decisions. Thus began a legacy of erratic, often passive, resource management based more on politics and in-house studies than on validated scientific informa tion. The world is a different place than it was 75 years ago. Human population growth, changes in land use, and ever more sophisticated technology affect the very fabric of life on Earth. As local-, regional-, and global-scale changes occur from human tampering with the environment, the integrity of natural ecosystems is threatened worldwide.

内容説明
This is a presentation of the Loch Vale Watershed study, which was initiated to help understanding of biogeochemical pathways as well as the effects of acid deposition in the alpine and subalpine environment of the Rocky Mountain National Park. The study characterizes precipitation, bedrock, soils, lakes and streams, aquatic organisms and woody vegetation. Amongh the topics addressed are sources and seasonal variations in acidic deposition, buffering of surface waters through soil processes, geochemical mass balance, the chemical composition of surface waters and nutrient and growth dynamics of old-growth spruce-fir forests. Methodological considerations are also discussed.
