Abstract
Biosphere reserves are internationally recognized landscapes that have been set aside to protect various ecological characteristics. The monitoring of ecological change within such reserves is a central component of biosphere reserve management, and traditional methods have proven difficult and costly. This paper explores an alternative technique using social indicators to monitor biophysical change. The technique may provide a practical “early warning system” for reserve managers. The paper reviews biological and sociological monitoring techniques and provides a theoretical framework for experimenting with social indicators. Several indicators of Olympic National Park Biosphere Reserve are developed to illustrate the potential of social indicators for monitoring biosphere reserves.

Biosphere II's water systems became polluted with too many nutrients. The crew had to clean their water by running it over mats of algae, which they later dried and stored. Also, as a symptom of further atmospheric imbalances, the level of dinitrogen oxide became dangerously high.
