Sample Index of Biotic Integrity (IBI) sites SAA Version 3.0 Version Date: 3/21/96 ------------------------------------------------------------ Identification Information Data Layer Name: ibi_fish Sample Index of Biotic Integrity (IBI) sites Description: This coverage was developed to illustrate the quality of riparian benthic habitat of a limited area of the SAA area. The sample sites were scatered all over the SAA area but primarily in Tennessee Keywords: index, biotic, integrity, fish, IBI Citation: Native Data Set Environment: Unix; Arc/Info 7.1 pathname: //ibi_fish.e00 Scale: 1:2,000,000 File Format: The data layer is in one Arc/Info point coverage and is available in compressed Arc/Info export format. Use Restrictions: Data set must be cited when used.

This code resulted from combining some of the condition codes listed above. 1 = not impaired; includes "e" and "ge" 2 = slightly impaired; includes "g" and "fg" 3 = moderately impaired; includes "f " and "pf " 4 = severly impaired; includes "p", "vpp", and "vp" Entity: Definition: Attributes: Entity: Definition: Attributes: ------------------------------------------------------------ Status Information Data Set Status: Available Release Date: ------------------------------------------------------------ Metadata Reference Information Date: 21 March 1996 Review Date: Contact: Neil Burns, EPA, 345 Courtland St., NE Atlanta, GA 30365 (404) 347-7109 ------------------------------------------------------------ Distribution Information Distribution Contact: Distribution Liability: File Compression Technique: UNIX compress, Arc/Info export format Transfer Size: ------------------------------------------------------------ Contact Information Contact Person: Neil Burns Contact Mail Address: EPA, 345 Courtland St., NE Atlanta, GA 30365 Contact Phone: (404) 347-7109 Contact Fax: (404) 347-1043 Contact email: NBB01@R4DGCOASTAL.R04.EPA.GOV ------------------------------------------------------------
