The primary goals were: (1) to determine if there are relationships (dependence) between the two data sets of surface water biota and multiple landscape metrics, (2) to determine if the relationships are significant between the landscape metrics and surface water properties, (3) to quantify the strength of relationships, and (4) to define the key landscape variable(s) that contributes to surface water quality. Therefore, the objectives were: (1) to explore the relationships among chemical and biological surface water properties and landscape data sets, (2) to quantify the magnitude of the relationship between each of the chemical and biological variables with the landscape metrics, and (3) to investigate the possibility of using chemical data, which is less expensive and easier to measure, as a surrogate for biological data to examine changes in landscape and related effect in water quality metrics.
