Tennessee Code Title 70. Wildlife Resources § 70-8-112

(1) Such species so closely resembles in appearance, at the point in question, a species that has been listed pursuant to such section that enforcement personnel would have substantial difficulty in attempting to differentiate between the listed and unlisted species;

(2) The effect of this substantial difficulty is an additional threat to an endangered or threatened species; and

(3) Such treatment of an unlisted species will substantially facilitate the enforcement and further the policy of this part.
