SEC. 2. FINDINGS.

    The Senate finds and declares the following:
            (1) The majority of American property owners recognize the 
        importance of protecting the environment, including the habitat 
        upon which endangered and threatened species depend.
            (2) Current Federal tax laws discourage placement of 
        privately held lands into endangered and threatened species 
        conservation agreements.
            (3) The Federal Government should assist landowners in the 
        goal of conserving endangered and threatened species and their 
        habitat.
            (4) If the environment is to be protected and preserved, 
        existing Federal tax laws must be modified or changed to 
        provide tax incentives to landowners to attain the goal of 
        conservation of endangered and threatened species and the 
        habitats they depend upon.
