None of the provisions of this Part shall be construed to apply retroactively or to prohibit importation into the state of wildlife which may be lawfully imported into the United States or lawfully taken and removed from another state or to prohibit entry into this state or the possession, transportation, exportation, processing, sale or offer for sale or shipment of any wildlife which has been determined to be an endangered or threatened species in this state but not in the state where originally taken if the person engaging in such activity demonstrates by substantial evidence that such wildlife was lawfully taken and lawfully removed from such state. Provided, however, that this section shall not be construed to permit the possession, transportation, exportation, processing, sale or offer for sale or shipment within this state of species of wildlife determined, pursuant to the Federal Endangered Species Act to be an endangered or threatened species, except as permitted by Subsection G of Section 1904 of this Part.
