Supplementary Notes. la. Ab&traet (Limit: 200 words)The Habitat Suitability Index (HSI) <strong>models</strong> presented in this publication aid inidentifying <strong>habitat</strong> variables important to the growth <strong>and</strong> survival of spotted bass(Micropterus punctulatus). Facts, ideas, <strong>and</strong> concepts obtained from the researchliterature <strong>and</strong> expert reviews are synthesized <strong>and</strong> presented in a format that canbe used for impact assessment. The <strong>models</strong> are hypotheses of species-<strong>habitat</strong>relationships, <strong>and</strong> model users should recognize that the degree of veracity ofthe HSI model, SI graphs, <strong>and</strong> assumptions will vary according to geographicalarea <strong>and</strong> the extent of the data base for individual variables.A brief discussion of selected Suitability Index (SI) <strong>curves</strong> as used in theInstream Flow Incremental Methodology (IFIM), <strong>and</strong> a discussion of SI <strong>curves</strong>available for the IFIM analysis of Spotted bass <strong>habitat</strong> are also inclUded.17.
