October 1985 Vol. X No. 10 Department of interior. U.S. Fish and Wildlife Service Technical Bulletin Endangered Species Program, Washington, D.C. 20240 New Notice Identifies Vertebrate Listing Candidates In the September 18, 1985, Federal Register, the Fish and Wildlife Service (FWS) issued a "Review of Vertebrate Wildlife," replacing and updating an ear- lier version that appeared in 1982. The main purpose of the new notice is to identify those native U.S. vertebrate taxa—fish, amphibians, reptiles, birds, and mammals—that are considered candidates for possible addition to the Federal List of Endangered and Threa- tened Wildlife, and to request comments and information that may assist in deter- mining whether or not to actually pro- pose such addition. The identified animals are placed in one of three categories that reflect their biological status: m Category 1 comprises taxa for which g the FWS currently has substantial a information on hand to support the S biological appropriateness of prop- osing to list as Endangered or Threatened. The golden-cheei<ed warbler fDendroica chrysopariaj is one of the 515 vertebrate (continued on page 12) taxa identified as candidates for future listing.

However, the MAD agreed to reroutethe ditch to avoid the population and to pre- clude public access, which under cur- rent conditions was resulting in significant trampling of the plant. The SESO staff, in cooperation with the U.S. Forest Service and California Department of Fish and Game (CDFG), participated in a site investigation of the Silver King Creek watershed in Alpine County, California.
