Requires the Secretary to publish a description of additional scientific and commercial data that would assist in the preparation of a recovery plan.

Directs the Secretary to: (1) solicit recommendations from the National Academy of Sciences and develop a list of qualified reviewers to participate in independent scientific review actions; and (2) appoint from such list three individuals who shall report on the scientific information and analyses on which final action is based.

Requires the Secretary, when consulting with a Federal agency to determine whether agency action will jeopardize an endangered or threatened species or destroy the critical habitat of such species, to: (1) consider information provided by affected States; and (2) allow any person who has sought agency authorization or funding for an action to participate in related consultations.
