345 commenserate with the amount of energy that went into their production. If this is true, then a top consumer in the food chain such as the Wood Stork must have a very high value to the ecosystem of which it is a part. Harvesting high concentrations of fish in drying pools, which obviates fish kills and maintains species diversity (Kushlan, 1976), is one way in which the Wood Stork is of serve to the ecosystem that supports it. Wood Storks and other colonial-nesting wading birds also contribute to the ecosystem by collecting minerals such as nitrogen over widespread areas in the food they catch and transporting it to the rookery area, where it becomes concentrated as excrement, with the potential of enhancing plant growth, the capturing of the sun's energy through the photosynthetic process. The Wood Stork in the south Florida ecosystem has a special value to man because it is an indicator of the healthy functioning of a regional ecosystem and processes that also support man in his agriculture and cities. The Wood Stork has demonstrated that exploitation of oscillating water patterns can be profitable. The bird might serve as an example to man that greater return per energy (and money) investment might be gained by learning to utilize the oscillating water patterns of south Florida than by trying to damp or destroy them. In the past 6 yrs (1971-76) Wood Storks in southwest Florida have demonstrated a resiliency that suggests that
