Table 1. Rationale for the holistic ecosystem health indicator weighted point system. Source: Aguilar (1999). Weight Category or indicator characteristics High Measures key resources and interactions, i.e., structure and function, in the social-ecological system and reflects the management objectives of the area. Indicators that reflect a greater correlation between the measurement and the actual health of the system receive a higher score. Intermediate Measures critical factors in the function and persistence of the system, but they are not central goals of the management strategy of the area Low Interactions between the indicator and ecosystem health are still unclear or the methods are not well developed. As the individual tests improve and information on their relevance to ecosystem health becomes clearer, these can be allocated a greater weight.
