2005 California Fish and Game Code Sections 4600 CHAPTER 6. BURROS

4600.  It is unlawful to kill, wound, capture, or have in possession
any undomesticated burro.
   An undomesticated burro is a wild burro or a burro which has not
been tamed or domesticated for a period of three years after its
capture.  The fact that a burro was killed, wounded, or captured on
publicly owned land, or on land owned by a person other than the
person who killed, wounded, or captured the burro is prima facie
evidence that the burro was an undomesticated burro at the time it
was killed, wounded, or captured.
   Neither the commission nor any other department or agency has any
power to modify the provisions of this section by any order, rule, or
regulation.
