Colorado Wildlife Federation The Habitat Stamp reauthorization bill, S 09-235, passed the General Assembly on May 1. Earlier it passed House Appropriations on April 29 and House Agriculture, Livestock and Natural Resources Committee on April 22, with an amendment 10-1. The amendment unfortunately provides that the legislature may pass a different bill by June 1, 2010 in lieu of this bill. The bill differs from the Senate bill. The current habitat stamp will expire at the end of 2010 and therefore, a reauthorization bill is necessary. The bill can be found by clicking the Legislation tab on the CWF home page.
