Entity_and_Attribute_Overview:
Each individual watershed has been evaluated by biologists for the presence of those perturbations, and if present those perturbations have been scored on a scale of 1 - 3 (1 being High: life cycle component eliminated, 2 - Medium: life cycle component reduced but not eliminated, or 3 - Low: general threat, no documented loss or reduction in life cycle component). This table is related to other tables in the EBTJV: allmetrics, ebtjv_subwatersheds, final_categories, model_results, node_prob_pruned, node_probabilities, perturb_biologists_ratings. The relationship is through the field called "HUC_CODE" (the unique HUC identification of the watershed).
