In the February 2003 issue (vol. 17, no. 1, p. 116 ) of Conservation Biology, Kent Redford's email address should have been revised by the publisher to read, and he is affiliated with the Wildlife Conservation Society; only Michael Wright is affiliated with The John D. and Catherine T. MacArthur Foundation. David Olson's current address is in Suva, Fiji. Additionally, on page 117, reference to the U.S. Fish and Wildlife Service is incorrect. It should read U.S. Forest Service. In Table 1, incorrect reference is made to U.S. Code of Federal Regulation under the column “Organization.” It should read U.S. Forest Service. The authors thank Joseph Dudley for pointing out their mistake. For the analysis of the U.S. Forest Service, the authors relied on the National Forest System Land and Resource Management Planning Rule, which was adopted 9 November 2000 (Federal Register 65:67514). Subsequent to the acceptance of the manuscript, the U.S. Forest Service proposed a number of changes to this rule. These proposed changes were published on 6 December 2002 in the Federal Register (67:72770-72816).
