#### About Ecosystem Modeling

An ecosystem model is an abstract, usually mathematical, representation of an ecological system, which is studied to gain a deeper understanding of the real system. Ecosystem models are formed by combining known ecological relations with data gathered from field observations. These model systems are then studied in order to make predictions about the dynamics of the real system. Often, the study of inaccuracies in the model (when compared to empirical observations) will lead to the generation of hypotheses about possible ecological relations that are not yet known or well understood. They also enable the simulation of ecological processes over very long periods of time. Ecosystem models have applications in a wide variety of disciplines, such as natural resource management, ecotoxicology and environmental health,agriculture, and wildlife conservation. (Wikipedia)

We are having a workshop in Auckland in 2 weeks to consider urban pressures on the horizon. The challenge is to think of new ideas, or issues poorly studied, rather than the usual problems or exacerbators of the usual problems. Your ideas would be welcome.
