In 2004, a proposal was submitted by Kenya to have B. worthingtoni listed on CITES Appendix II. The actual status of the species was unknown, but it was reasoned that the Kenyan proposal was justified due to the species' restricted geographic range, habitat loss, demand by reptile collectors and the existence of illegal trade.[9] In 2019, B. worthingtoni was listed as "Vulnerable" by the International Union for Conservation of Nature.[1]
