Comparison with the 1987 List. Of the 30 species on the 1987 list, 24 are retained (including 17 for which minor inter-Regional changes are made) and 6 are deleted (3--roseate tern, black-capped vireo, golden-cheeked warbler--because of Endangered or Threatened species listing throughout their ranges since 1987; 3--Harris' hawk, gull-billed tern, ladder-backed woodpecker--because of lack of convincing evidence that continued listing is warranted). Ninety-eight species are added to the list, resulting in a net gain of 92 species and a current (1995) list of 122 species.

Table 3 provides a side-by-side comparison of the data sources, participants, and selection criteria used in developing the 1987 and 1995 lists.

Comparison with Other Lists. Of 122 species on the 1995 National list, 44 are also of high priority on one or more PIF regional lists and 41 are listed as Category 1 or 2 "candidates" in one or more regions. In other words, 44 (17%) of the 254 PIF species (Research Working Group 1992) and 41 (67%) of the 61 bird "candidate" species (USFWS 1994) also qualify as species of management concern. A "preliminary list of species deserving additional conservation measures" found in a 1990 report to Congress (U.S. Department of the Interior 1990) includes 72 species that fall within the focus of this exercise, and 48 (67%) of them qualify as species of management concern.

Fifteen (79%) of the 19 species on the National Audubon Society's "Blue" list (Tate 1986) are listed here as species of concern, as are 13 (41%) of 32 "Special Concern" species and 4 (21%) of 19 "Local Concern" species. Of 30 species that Graham (1990) suggested "won't be with us" in the year 2001 without renewed conservation attention, 13 (43%) are also on the management concern list (and 15 others are Federally listed as Endangered or Threatened).
