Catalog No. <br />Scoring and Prioritization of Sites <br />Corps of Engineers, University of <br />Several classification systems were evaluated for suitability in <br />classifying and ranking bottomland habitats that were perceived to be <br />potentially valuable for providing endangered fish habitat (Cowardin et al. <br />1979; Brinson 1992; The Nature Conservancy 1992; Lyon 1993). Constraints of <br />time and personnel precluded using these detailed classification systems for <br />the bottomland inventory. Instead, a five-step procedure was developed in <br />1994 by a three-member team2 to score and rank bottomland sites. Prioritizing <br />sites assisted in identifying locations where staff gauges and river transects <br />would be established in 1994 to predict flows necessary to inundate a <br />bottomland site. The five steps were: <br />Step 1: Initially, criteria were developed to assist in discriminating <br />and prioritizing bottomland sites using available photographic imagery and the <br />most current biological information. The initial list included area, <br />ownership, proximity to razorback sucker use (historical and current), water <br />-------------------------------------------- <br />2 USFWS: Pat Nelson, Coordinator of the Floodplain Habitat Restoration Program, Region 6, Denver, Colorado; <br />Bob Burdick.,Fishery Biologist.
