ABSTRACT
This chapter provides case studies that have been created to allow for individual and group analysis, as well as creating talking points between students and instructor in a shared learning environment. Environmental decisions that involve watershed management are particularly interesting because they include considerations of both terrestrial and aquatic resources; they span interactions on land and water. Fertilizers for agricultural and residential uses make up the majority of the nutrients leaching into the watershed river system, ultimately aggregating into the Gulf of Mexico. A survey of the watershed shows residential fertilizer application occurs 25% of the time by private party and 75% of the time by contracted services. Only a few communities along the watershed require buffer zones. Buffer zones are used to limit the amount of runoff from developed sites that are near waterways.
