In Table 13, the areas, area factors, multiplication factors, and scores for seasonally and permanently flooded swamp are reversed, but the total score in this example does not change. Replace the table with the following: Table 13: Scoring Swamps for Fish Habitat (Seasonally Flooded; Permanently Flooded) Swamp Present Total Area Factor Multiplication Score Containing (check) Area (from Table Factor Fish Habitat (ha) 8) Seasonally x 52.9 1.0 10 10 Flooded Swamp Permanently x 4.0 0.2 1 2 Flooded Swamp Total Score for Swamp (maximum 20 points) 12
