SEC. 2. PURPOSE.
The purpose of this Act is to establish a risk assessment process to prevent the introduction into, and establishment in, the United States of nonnative wildlife species that will cause or are likely to cause economic or environmental harm or harm to other animal speciesÃ"¢ health or human health.
SEC. 3. RISK ASSESSMENT PROCESS FOR IMPORTATION OF NONNATIVE WILDLIFE SPECIES.
(a) In General- The Secretary of the Interior, acting through the United States Fish and Wildlife Service, shall promulgate regulations that establish a process for assessing the risk of all nonnative wildlife species proposed for importation into the United States, other than nonnative wildlife species that are included in the list of approved species issued under section 4.
(b) Factors To Be Considered- The regulations promulgated under subsection (a) shall include consideration of--
(1) the identity of the organism to the species level, including to the extent possible specific information on its subspecies and genetic identity;
(2) the native range of the species;
(3) whether the species has established or spread, or caused harm to the economy, the environment, or other animal species or human health in ecosystems in or ecosystems that are similar to those in the United States;
(4) the likelihood that environmental conditions suitable for the establishment or spread of the species exist in the United States;
(5) the likelihood of establishment of the species in the United States;
(6) the likelihood of spread of the species in the United States;
(7) the likelihood that the species would harm wildlife resources in the United States;
(8) the likelihood that the species would harm native species that are rare or native species that have been listed as threatened species or endangered species in the United States under the Endangered Species Act of 1973 (16 U.S.C. 1531 et seq.);
(9) the likelihood that the species would harm habitats or ecosystems in the United States;
(10) the likelihood that pathogenic species or parasitic species may accompany the species proposed for importation; and
(11) other factors important to assessing the risks associated with the species, consistent with the purpose under section 2.
