Current (September 2005) Congressional Evaluation of the Endangered Species Act of 1973
There are now 50 bills in the 109th Congress dealing with Endangered Species Policy. A complete list, text, and discussion of these can be found at http://thomas.loc.gov/ Search for the word phrase "endangered species" to find them. An excellent source of information about important bills and the views of congress can be found on the web pages of relevant committees:
Of greatest significance is Rep. Pombo’s (R-Cal) latest proposed reauthorization (and rewriting) of the ESA. To track this bill search for the status of HR 3824. As of this writing it is just emerging from The House Committee on Resources hearing. The Thomas site above allows you to track the activity of a bill.
