Selected waters from the high alpine zone within Grand Teton National Park, Wyoming, were analyzed for populations of indicator bacteria during the past three summers to determine the influence of various factors on the quality of these waters. In general the water quality was not significantly influenced by the presence or absence of human visitors but rather by the nature of the biological community through which the streams flowed. A minority of the coliforms that were recovered from all of the sites proved to be fecal coliforms. The fecal streptococci isolated were identified as the species that were found primarily in the fecal material of the native rodent and moose populations. It is concluded that management questions that relate to the carrying capacity of alpine areas should be approached with the aid of other biological parameters along with levels of indicator bacteria in the streams.
在过去三个夏天里，对怀俄明州大提顿国家公园内高山区的部分水域进行了分析，以确定指示菌数量，从而判定各种因素对这些水域水质的影响。总体而言，水质受人类访客的有无影响不大，而是受溪流流经的生物群落性质影响。从所有采样点回收的大肠菌群中，少数被证明是粪大肠菌群。分离出的粪链球菌被鉴定为主要存在于当地啮齿动物和驼鹿粪便中的物种。研究得出结论，与高寒地区承载能力相关的管理问题，应借助其他生物学参数以及溪流中指示菌的水平来解决。
