 FR Doc 04-10426
The permit application includes a proposed Programmatic Southern Idaho Ground Squirrel Candidate Conservation Agreement with Assurances (Agreement) between the Service, the Idaho Department of Fish and Game, and the Idaho Governor's Office of Species Conservation.
Under the proposed Agreement, the parties would implement conservation measures for southern Idaho ground squirrels (Spermophilus brunneus endemicus) over approximately 1,046,569 acres in Adams, Washington, Payette, and Gem counties, Idaho.
The intent of the Agreement is to conserve southern Idaho ground squirrels (SIGS) by protecting and enhancing SIGS habitat and populations, and reintroducing SIGS into currently unoccupied suitable habitat, in a manner that is consistent with the non-Federal landowner's land use activities and the Agreement.
